[0003] Abrasion of the outer layer or epidermis of the skin is desirable to smooth or blend scars, blemishes, or other skin conditions that may be caused by, for example, acne, sun exposure, and aging. Standard techniques used to abrade the skin have generally been separated into two fields referred to as dermabrasion and microdermabrasion. Both techniques remove portions of the epidermis called the stratum corneum, which the body interprets as a mild injury. The body then replaces the lost skin cells, resulting in a new outer layer of skin. Additionally, despite the mild edema and erythema associated with the procedures, the skin looks and feels smoother because of the new outer layer of skin.

[0075] FIG. 1 illustrates one embodiment of a skin treatment system 10. As noted herein, in some arrangements, the system 10 is configured to be used as a self-administered system by a subject undergoing skin treatment (e.g., dermabrasion or exfoliating procedure). However, in other embodiments, the system 10 may be used by someone other than the individual being treated (e.g., by an aesthetician, a dermatologist, another skincare professional, etc.) to perform a skin treatment procedure, as desired or required. In some embodiments, the system 10 is used to perform a procedure as a stand-alone treatment and/or as part of an overall treatment scheme (e.g., one that includes visits to an aesthetician or other professional).

[0076] In some embodiments, the system 10 can be used to perform one or more skin treatment procedures on a subject's skin by the subject itself. Such procedures or treatments can be performed between visits to a skin treatment professional and/or facility. For example, the various embodiments disclosed herein can be used to perform such intermediate treatments.

[0077] In some arrangements, self-administered or intermediate treatments are performed by the various embodiments disclosed herein, whereas professional treatments may be performed using a different device or system. However, in other arrangements, professional treatment can use the same device or system, as desired or required. In some embodiments, although the same system is used by both the subject and a skin treatment professional or other administrator of the procedure, the settings of the system can be modified. For instance, the system can be used to provide a greater suction or vacuum when used by the professional or other r user.

[0078] With reference to FIG. 1, the system (e.g., the handpiece, the handheld device, etc.) 10 can include a main body portion 20. The main body portion 20 can comprise an outer housing that the user grasps and manipulates during operation of the system. In the illustrated arrangement, the main body portion 20 comprises an outer housing 20A, 20B that encloses and protects the internal components of the system. As illustrated, the housing can include two separate portions 20A, 20B that are configured to secure to one another along a connection interface 20C. In other arrangements, however, a system 10 can include a single or unitary housing and/or more than two portions (e.g., 3, 4, 5, more than 5, etc.) that are configured to secure to each other to form the outer housing, as desired or required. As illustrated in the embodiment of FIG. 1, the housing of the system can include a clamshell design.

[0079] The two or more portions 20A, 20B of a housing can be configured to be removably secured to each other via one or more releasable connections or methods. For instance, housing sections or portions 20A, 20B can be coupled to one another using one or more friction fit, press fit or snap fit connections. In other embodiments, glues or other adhesives, other mechanical fasteners (e.g., screws, rivets, flanges, tabs, other interlocking features, etc.) and/or any other securement method or technology can be used to couple two or more housing sections or portions of a system, as desired or required.

[0080] In alternative arrangements, the housing can include a single, monolithic structure. The housing can include a recess or opening into which one or more internal components may be inserted. By way of example, such a recess or opening can be located along the top or distal end of the system. In other embodiments, a recess or opening for a monolithically designed housing can be located along any other portion or area of the housing (e.g., the bottom or proximal end, a side, etc.), either in lieu of or in addition to an opening along the top or distal end. One or more caps or other sealing portions and/or another component of the system can be used to close any recesses or openings after the system is assembled and ready for use.

[0081] According to some embodiments, the housing and/or other external components of the system 10 comprise one or more thermoplastic materials that provide the desired or required resistance to elements that the system may be subjected, such as, for example, water or other liquids, chemicals or other substances, temperature variations, inadvertent dropping, vibration and/or other mechanical impact, etc.

[0082] In some configurations, at least a portion of the housing and/or other exterior areas of the main body portion 20 include surface texturing to facilitate with the handling of the system by a user. Such surface texturing can improve the overall feel and/or comfort of the system in the user's hand, reduce the likelihood of slippage and/or provide any other benefits or advantages. In some embodiments, such surface texturing can be included as a result of the manufacturing process in the component that will be exposed to the exterior of the system. Alternatively, such texturing can be applied after manufacture of the corresponding component(s) via the application of coatings or layers, roughening and/or the like. Thus, the texturing can be created while the housing components are being molded or otherwise formed or it can be created after formation of the components, as desired or required.

[0083] In some embodiments, the system is manufactured to be at least partially waterproof or water resistant. For instance, the system can be designed and otherwise manufactured to satisfy certain waterproofing standards. By way of example, the system can be configured to meet the requirements of IPxx, the ingress protection (IP) protection grade system drafted by IEC (International Electrotechnical Commission), which classifies electrical appliances according to their dust and moisture resistance. In some embodiments, the system complies with one or more IPxx standards (e.g., IP22).

[0084] As noted above, the system can be designed, manufactured and otherwise configured to meet certain standards with respect to drops, impacts, vibrations and the like. Further, in some embodiments, the system and/or its components (e.g., housing, internal components, etc.) are configured to include a temperature resistance of not only reasonably expected ambient conditions (e.g., 10 to 40 degrees C.), but also relatively extreme temperature conditions (e.g., −10 degrees C to 50 degrees C. or higher). Further, the system can be configured to provide the necessary resistance to oils, chemicals and/or other materials to which a user may expose the system. For instance, the system 10 can be adapted to protect the housing and/or other system components against liquids and/or other fluids or materials used during the cleaning or sanitization and/or other maintenance of the system. According to some embodiments, the system is configured to sustain a drop from 1 meter or more (e.g., 1 m, 1.5 m, 2 m, 0 m to 1 m, 0 m to 2 m, 1.5 to 2 m, values between the foregoing ranges or values, etc.). In other arrangements, the system is configured to sustain a drop from greater than 2 meters (e.g., 2 m to 2.5 m, 2.5 m to 3 m, 2 m to 3 m, 2 m to 4 m, greater than 4 meters, distances between the foregoing values and ranges, etc.).

[0085] With continued attention to the embodiment illustrated in FIG. 1, the system 10 can include a waste container 200 that is configured to be removably secured to a side or area of the main body portion 20 (e.g., at least partially, to the housing). As shown, the waste container can be shaped, sized and otherwise configured to match the slopes, contours, lines and/or other exterior features of the adjacent components (e.g., the main body portion 20) of the system. As a result, the system 10 can include a smooth and seamless overall shape. Such a configuration can enhance the feel to the user and/or the look of the system. According to some embodiments, waste container and/or other portions of the system comprise, without limitation, one or more of the following materials: acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polypropylene (PP), thermoplastic elastomers (TPE) and/or the like. However, in other arrangements, one or more components and/or portions of the system include other materials (e.g., other thermoplastic materials, metals or alloys, glass, other natural or synthetic materials, etc.), either in lieu of or in addition to the specific thermoplastic materials listed herein.

[0086] In some embodiments, some or all portions of the waste container 200 that are exposed to the exterior of the system 10 are at least partially transparent or translucent to permit a user to view inside the waste container 200 (e.g., during use of the system, between procedures, etc.). The waste container 200 can comprise one or more thermoplastic materials that are transparent or translucent, as desired or required. In the depicted arrangement, the entire waste container 200 or substantially the entire waste container 200 is transparent or translucent. However, in alternative configurations, only a portion of the waste container is transparent or translucent. For example, the waste container can include a window or other area that is transparent or translucent, while the remainder of the waste container is not transparent or translucent (e.g., is opaque, solid, etc.). The area of the window or other viewable portion can be 5% to 40% (e.g., 5 to 40, 10 to 40, 10 to 30, 10 to 20, 5 to 25, 10 to 20%, percentages between the foregoing values or ranges, etc.) of the overall exterior surface area of the system. In other embodiments, the area or size of the window or viewable portion is less than 5% or greater than 40% of the overall exterior surface area of the system. In other embodiments, the waste container does not include any transparent, translucent and/or other viewable portions.

[0087] As discussed in greater detail below, the system 10 can include one or more illumination sources (e.g., LED) that provide light to the interior of the waste container 200. Such illumination can serve one or more purposes and/or provide one or more benefits or advantages to the system and the user. For instance, illumination of the waste container can facilitate in assessing or otherwise evaluating (e.g., qualitatively, quantitatively, comparatively, etc.) the effectiveness of a skin treatment procedure. In some embodiments, the turbidity or cloudiness of the spend fluid and other waste collected within the waste container 200 can provide certain insight to a user regarding how well a treatment procedure (or a step or portion of a procedure) was performed and/or regarding some other aspect of a procedure itself and/or the person who is undergoing the procedure (e.g., how much dirt, sebum and/or other materials were removed from the subject, the effectiveness in removing certain types of materials, etc.).

[0088] In some embodiments, the system can include one or more sensors to help analyze and quantitatively assess the contents of the waste container 200. For example, the system 10 can include a turbidity sensor or similar sensor adjacent one or more portions of the waste container 200. Such sensors can be built into the system and/or can be external to the system, as desired or required. In some embodiments, such sensors are light-based sensors that determine how cloudy or clear the contents collected in the waste container are. In other arrangements, other types of sensors can be used, such as, for example, pH sensors, temperature sensors, sensors that are configured to detect or at least approximate the presence of certain components (e.g., salts, oils, etc.) and/or the like.

[0089] With continued reference to FIG. 1, the system 10 can additionally include a tip 300 located along the top or distal end of the system 10. In some arrangements, as depicted in FIG. 1, the tip 300 is angled relative to a vertical or longitudinal axis of the system. As illustrated in FIG. 9A, such an angle Al between the vertical or longitudinal axis L of the device and the tip 300 can be 5 to 50 degrees (e.g., 5 to 50, 5 to 25, 25 to 50, 10 to 40, 10 to 30, 15 to 30, 20 to 30, 20 to 45, 15 to 45 degrees, angles between the foregoing angles and ranges, etc.). In other arrangements, the angle Al can be less than 5 degrees or greater than 50 degrees, as desired or required. The angled design of the distal end of the tip 300 can facilitate the user (e.g., the subject undergoing a self-administered treatment procedure, an aesthetician or other professional performing a procedure on a subject, etc.) during the execution of a treatment procedure. An angled distal end of the tip 300 can effectively increase the surface area of the portion of the tip that actually contacts the skin surface being treated, enhance the ability of the user to maintain contact with the targeted skin surface, improve the comfort and ergonomic features for the user and/or provide one or more additional advantages or benefits, as desired or required.

[0090] As shown in FIG. 1, the tip 300 can be sized, shaped and otherwise configured to maintain a smooth or substantially smooth outer shape of the system 10. In other words, the exterior lines and overall shape of the system 10 can be generally smooth with continuous (e.g., uninterrupted) contours or lines. Additional details regarding the tip 300 are provided below.

[0091] The system 10 can be configured to receive a pod, vial or other container 400. In some embodiments, such a pod 400 contains one or more treatment serums, other liquids and/or other treatment materials. The contents of the pod 400, once the pod 400 has been secured to the system 10, can be placed in fluid communication with one or more portions (e.g., fluid conduits or passages, other internal portions or components of the system, etc.) to selectively transfer the contents from the pod to the tip (e.g., by activating a fluid pump or otherwise generating a vacuum or suction force along the tip).

[0092] As is the case with the tip 300 in the illustrated embodiment, once secured to the system 10, the pod or other container 400 can be angled relative to a vertical or longitudinal axis of the system. With reference to FIG. 9A, such an angle A2 between the vertical or longitudinal axis L of the device and the longitudinal axis of the pod or other container 400 (and thus, the longitudinal axis of the receiving area of the system that receives the pod or container) can be 5 to 50 degrees (e.g., 5 to 50, 5 to 25, 25 to 50, 10 to 40, 15 to 45 degrees, angles between the foregoing angles and ranges, etc.). In other arrangements, the angle A2 can be less than 5 degrees or greater than 50 degrees, as desired or required. Therefore, in some arrangements, both tip 300 and the pod or container 400 (once secured to the system) are angled relative to the longitudinal axis of the system and/or to one another, as desired or required. In some embodiments, the overall shape of the system forms a “Y.” This becomes more evident when a pod or other container 400 and a tip 300 are secured to the system (e.g., handpiece, handheld device) 10. See, for example, FIGS. 1 to 3B, 7A, 7B, 9A and 9B. Thus, in some embodiments, the system 10 comprises a “Y” shape with the upper portion of the “Y” formed by the tip and the container, and the lower portion of the “Y” formed by the main body portion (which may include a waste container).

[0093] As discussed in greater detail below, the system 10 can include a battery (e.g., an internal rechargeable battery) to selectively energize the various electrical components of the system (e.g., fluid pump, lights, sensors, processors, etc.). Accordingly, in some embodiments, as depicted in FIG. 1, the main body portion 20 is sized, shaped and otherwise adapted to fit within a docking station 90 and/or vice versa. The docking station 90 can include a recess or opening located in a base 94 for receiving the main body portion (e.g., the bottom of the main body portion). In some arrangements, the docking station is configured to securely maintain the main body portion, and thus the system, in an upright or vertical orientation when the main body portion is placed therein and secured thereto.

[0094] With continued reference to FIG. 1, the docking station 90 can include a base 94 (e.g., into which the main body portion 20 is configured to be positioned). As shown, a cable or other electrical connector 98 can electrically couple the base 94 to an electrical energy source (e.g., AC power). In other embodiments, the system is configured to receive one or more batteries (e.g., individual battery(ies), battery packs, etc.) that can be replaceably removed from the system for recharging (e.g., using a separate charger or other charging device), replacement, etc., as desired or required.

[0095] FIGS. 2A and 2B illustrate different perspective views of the skin treatment system 10 of FIG. 1. As illustrated in FIG. 2B, the system (e.g., handpiece, handheld device, etc.) 10 can include one or more controllers 30 along its exterior surface (e.g., along the outer housing of the main body portion 20). In the depicted embodiment, the system 10 comprises an ON/OFF button 32 and “plus” and “minus” buttons 34, 36 to control the pressure, flowrate and/or other properties associated with a liquid pump situated within the system. In other embodiments, the controllers include switches, dials, a touchscreen (e.g., on the device and/or a separate device that is operatively coupled to the device, etc.). Additional information regarding the liquid pump and other internal components of the system are provided below.

[0096] In some embodiments, the buttons or other controllers 30, 32, 34, 36 are positioned such that a user can easily press or otherwise manipulate the controllers while grasping and using the system 10 (e.g., using a single hand to both grasp the device/system and make changes to an operational parameter of the device/system using one or more controllers). For example, the position, orientation, configuration and/or other details regarding the controllers can advantageously permit a user to adjust the controllers using a single hand while performing a skin treatment procedure (e.g., while still grasping and manipulating the system). In other embodiments, however, the operation and/or control of the system 10 can be performed differently (e.g., without the use of buttons or other controllers incorporated into the main body portion 20 or other surface of the system), as desired or required. For instance, the system 10 can be configured to be operatively coupled (e.g., using one or more wireless or wired connections) to a separate computing device, such as, a smartphone, a tablet, a personal computer, etc. In such configurations, the separate computing device can be adapted to allow a user to make the necessary adjustments via a user interface (e.g., an application, program, etc.).

[0097] With further reference to FIG. 2B, the system 10 can also include one or more indicators or other output 40. For example, the system 10 can comprise one or more status lights, displays and/or the like that provide information to the user. In some embodiments, the outputs 40 are light emitting diodes (LEDs) that are configured to inform the user of certain conditions or occurrences, such as, for instance, whether the system is powered on, the current pressure/vacuum level of the internal fluid pump, the flowrate of the fluid being transferred from the pod or other container secured to the system to the tip, the battery life of the battery or other power source of the system, the system temperature, elapsed time or remaining time for a procedure and/or the like. As noted herein, the system 10 can be operatively coupled (e.g., wirelessly, using a wired connection, etc.) to a separate computing device (e.g., smartphone, tablet, personal computer, network, cloud or similar infrastructure, etc.) that can display such information to the user, either in lieu of or in addition to any indicators or outputs 40 positioned on the system (e.g., the main body portion 20) itself.

[0098] In some embodiments, one or more of the controllers and/or the indicators associated with a specific device or system are provided on a separate device, component and/or system. For instance, such a separate device can include, without limitation, a smartphone, a tablet, a main or system component to which the system can operatively couple (e.g., a tower or console, a main processing unit, etc.), another computer device (e.g., a personal computer, a network, a cloud infrastructure, etc.), a separate input/output device, etc., as desired or required.

[0099] FIGS. 3A and 3B illustrate different side views of the system 10 of FIG. 1. Likewise, FIGS. 4A and 4B illustrate front and rear views of the system 10 of FIG. 1. Further, FIG. 5 illustrates a top view of the system 10 of FIG. 1. As illustrated in the bottom view of the system 10 in FIG. 6, the system 10 can include an electrical pad or other electrical contact area 70 along or near the bottom end. Such an electrical pad or contact area 70 can be sized, shaped, positioned and otherwise configured to contact a corresponding electrical contact area (not shown) of the charging/docking station 90. Thus, the battery(ies), battery pack, other rechargeable power source, etc. included in the system (e.g., handpiece) 10 can be advantageously charged once the main body portion is docked. In other embodiments, such electrical pads or contact areas can be positioned along different portions of the system and/or the docking station 90, as desired or required. In some arrangements, the battery or batteries of the system 10 can be charged using a hardwired connection that plugs into the main body portion or other section or component of the system 10, using inductive charging technology and/or the like. In yet other embodiments, the system 10 can be adapted to receive disposable or non-rechargeable batteries.

[0100] FIG. 7A illustrates a partially exploded perspective view of the treatment system (e.g., handpiece, handheld device, etc.) 10 of FIG. 1 with the waste canister 200 separated from the main body portion 20. As shown, the main body portion 20 can include upper and lower recesses or openings 26, 28 that are shaped, sized and otherwise configured to receive corresponding portions (e.g., tabs, extensions, etc.) 210, 220 of the waste container 200. In some embodiments, for example, a lower tab or extension 220 of the waste container 200 can include a reflector portion that is configured to be placed adjacent one or more LEDs (and/or other light emitting device or sources) of the main body portion 20 once the waste container 200 has been properly secured to the main body portion. Such a reflector portion can help at least partially disperse and/or distribute the light from the LEDs or other light source to create a desired illumination effect within, around and/or the vicinity of the waste container 200. Further, the upper portion 210 of the waste container 200 can include the necessary hydraulic and/or other fluidic connections and/or components to facilitate the delivery of waste materials (e.g., spent fluid, removed tissue, other waste, etc.) into the interior of the waste canister or container 200, as desired or required. In some embodiments, the waste container or canister 200 is configured to reversibly lock relative to the main body portion 20 of the system 10 to ensure that waste materials are predictably delivered into the waste container 200. In some embodiments, the container includes an air bleed opening or other venting feature (e.g., to facilitate with transfer of fluids to the container). Further the container can include one or more markings, such as, for example, volume graduation marks, a maximum fill line and/or the like.

[0101] FIG. 7B illustrates a different exploded perspective view of the skin treatment system 10 of FIG. 1 with the waste canister or container 200 secured to the main body portion 20, but the tip 300 and a pod or other treatment material container 400 separated from the main body portion 20. As shown by the arrows in FIG. 7B, the tip 300 can be secured to a corresponding tip-receiving area 50 of the main body portion 20, and the pod or other container 400 can be secured to a corresponding receiving area 60.

[0102] In some embodiments, the system can be activated and used (e.g., to perform a desired skin treatment procedure) once the tip and container (e.g., pod) have been secured to the housing or main body portion 20 of the system. In some arrangements, the system will not be permitted to be electrically activated (e.g., to turn on) unless both the tip and a container are appropriately secured to the system. In some embodiments, the system includes sensors (e.g., RFID or other identification tag readers) that help ensure that appropriate tip and/or container (e.g., pod) have been secured to the system. In some arrangements, the system can be configured to turn on only when acceptable tips and/or containers have been secured to the corresponding portions of the system. This can help improve efficacy and safety of a skin treatment procedure being performed using any of the embodiments of the system disclosed herein or equivalents thereof.

[0103] With continued reference to FIG. 7B, the tip-receiving area 50 can include a protruding portion (e.g., a circular protruding portion) that is shaped, sized and otherwise configured to receive a removable (e.g., disposable) tip 300. The tip-receiving area 50 can include one or more fluid delivery ports or openings 54 and one or more waste ports or openings 52. Such ports or openings 52, 54 can be positioned, sized, shaped and/or otherwise adapted to align (e.g., or substantially align) and be placed in fluid communication with corresponding fluid passages and/or ports of the tip 300. Further, one or more O-rings and/or other sealing members 58 can be used at or near the tip/tip-receiving area interface to prevent or reduce the likelihood of leaks of treatment fluid/materials and/or waste materials between transferred to and/or from the tip 300 during operation of the system.

[0104] As depicted in the cross-sectional view of FIG. 9B, the receiving area 60 of the main body portion 20 can include a spike or other piercing or penetrating member or feature 62 that is configured to penetrate or otherwise undermine a septum, membrane or other portion of the pod or container 400 that is positioned within the receiving area. Such a piercing member 62 can be cannulated to access the interior of the pod 400 and to provide a fluid pathway from the interior of the pod to one or more conduits or other fluid passages of the system once the pod is secured to the system (e.g., within the receiving area). Accordingly, pods or other treatment material containers 400 configured for use with the system 10 can comprise a membrane, septum and/or other penetrable portion or member to access its interior portion and contents. Such membranes or other members can include one or more flexible, semi-rigid and/or rigid materials and/or construction, such as, for example, thermoplastic materials, rubber, metal or alloys (e.g., aluminum) and/or the like. Additional details regarding pods and other containers 400 for use with the system 10 are provided below.

[0105] FIG. 8 illustrates a perspective view of the treatment system (e.g., handpiece or handheld device) 10 of FIG. 1 with one portion of the housing removed to expose at least some of the interior components of the system. In the illustrated embodiment, one of the two clamshell pieces that make up the main body portion or housing of the system has been hidden or eliminated. As shown, the system 10 can include a cylindrical member or portion 150 along the receiving area 60. In some embodiments, the cylindrical member 150 is sized, shaped and otherwise configured to receive a similarly shaped pod or other container (not shown in FIG. 8). As noted above, the system 10 can include a piercing member 62 within the interior of the receiving area (e.g., at or along the bottom of the cylindrical member 150) to access the interior of the pod or other container that is properly secured therein.

[0106] With continued reference to FIG. 8, the interior of the main body portion can include a circuit board and/or other electronics 110 that are configured to house the various components (e.g., electronic components) of the system, including without limitation, indicator lights and/or other outputs 40, controllers 30, 32, 34, 36 (e.g., ON/OFF button, pressure modification buttons, etc.), processor and/or the like. The interior of the system 10 can also include one or more batteries or other power sources 120 and one or more pumps (e.g., liquid pumps) 130, as desired or required.

[0107] As noted herein, batteries 120 included in the system 10 can be rechargeable to permit a user to recharge the battery or batteries between procedures. For instance, in some embodiments, such batteries 120 can be recharged by positioning the main body portion in a docking station 90 (see, e.g., FIG. 1) that is electrically coupled to AC power or another electrical power source. In alternative configurations, the battery(ies), battery pack(s) and/or other power source are configured to be removably positioned within a portion or area of the system. Thus, such batteries can be removed for replacement, disposal, recharging (e.g., in a separate charger or charging device), inspection and/or the like.

[0108] In some arrangements, the pump (e.g., liquid pump) 130 included in the system 10 is in fluid communication with the waste conduit system 144, 146 of the system. As shown, the waste conduit system can include at least one conduit or line 144 that extends from or near the tip receiving area 50 to the pump 130 and at least one conduit or line 146 that extends from the pump 130 to or near the waste container or canister 200.

[0109] According to some configurations, the pump 130 comprises a liquid pump that contacts (e.g., directly or indirectly) spent liquid and/or other waste materials being transferred from the tip to the waste canister 200. This is contrasted with alternative designs that utilize an air pump to create vacuum within a waste conduit system, but do not actually contact the waste stream being removed. However, for any of the system embodiments disclosed herein, an air pump can be used, either in lieu of or in addition to a liquid pump.

[0110] In some embodiments, the pump 130 comprises a diaphragm pump. However, in other embodiments, a different type of pump can be used, as desired or required. For instance, the pump 130 can include, a peristaltic pump (disc-based peristaltic diaphragm pump), a piezoelectric pump, a gear pump, a piston pump, a syringe, another type of micro pump and/or the like. In some embodiments, the pump is able to reliably transfer fluids to and/or from the working end (e.g., from a pod or other container to the tip, from the tip to a waste bin or container, etc.) regardless of the position or orientation of the system (e.g., handpiece, handheld device).

[0111] In some embodiments, the use of a liquid pump (e.g., a pump that comes in direct contact with the waste stream being removed from the tip of the system) can allow the pump to create a desired pressure and/or suction effect along the tip of the system during use. For example, the use of such pumps (e.g., diaphragm pump) can allow the system to operate using lower pressures and vacuums. Accordingly, the resulting skin treatment procedure can be more gentle, safer and/or pleasant to the user.

[0112] However, in other embodiments, non-liquid based pumps are included in the system (e.g., handpiece), either in lieu of or in additional to liquid pumps. In some embodiments, non-liquid pumps comprise air-based pumps (e.g., pumps that are configured that move air, either continuously or intermittently).

[0113] According to some embodiments, the pump (e.g., liquid pump) 130 is configured to create a maximum pressure or vacuum within the waste conduits or lines 144, 146, and thus along the tip 300, of 5 pounds per square inch (psi). In some arrangements, the amount of pressure or vacuum that is generated by the pump can be between 0 and 5 psi (e.g., 0 to 5, 0 to 4, 0 to 3, 0 to 2, 0 to 1, 1 to 5, 1 to 4, 2 to 5, 3 to 5 psi, values between the foregoing, etc.). However, in other embodiments, the liquid pump 130 is configured to generate a maximum pressure or vacuum greater than 5 psi (e.g., 5 to 6, 6 to 7, 7 to 8, 8 to 9, 9 to 10 psi, values between the foregoing, values greater than 10 psi, etc.), as desired or required.

[0114] In some embodiments, the system 10 is configured to include two or more (e.g., 2, 3, 4, 5, more than 5, etc.) specific pressure or vacuum levels or values at which the pump 130 can operate. However, in other arrangements, the system 10 can be adapted to permit a user to select any specific pressure or vacuum range. For example, in such configurations, the system can include a dial or other modifiable controller that is not limited to specific (e.g., stepwise) levels of pressure or vacuum. Regardless of the exact configuration of the pump and its operational parameters, the system can include one or more controllers 30 to permit a user to easily and predictably make changes to pressure (e.g., positive or negative) during use of the system. In some embodiments, the system 10 can also be configured to permit a user to modify one or more other operational aspects of the pump 130, such as, for instance, flowrate, pulse rate (e.g., if fluid and/or the associated pressure/vacuum is delivered discontinuously), etc.

[0115] According to some embodiments, a pump of the system can be configured to deliver or transfer fluid and/or other treatment materials from a container (e.g., pod) to the tip or working end of the system (e.g., along the system-skin surface interface during use). This can be done in lieu of or in addition to using a pump to draw waste fluids away from the working end (e.g., to a waste bin, canister or other container). In some embodiments, at least one pump is used help deliver fluids and/or other materials to the skin from a treatment material source (e.g., pod, other container, etc.) while at least one pump is used help transfer waste from the working end to a waste container or canister.

[0116] With further attention to FIG. 8, as noted above, the system 10 can also include one or more identification tag readers 160. As shown, the reader 160 can be positioned at or near the receiving area 60 for the pod or other container (not shown). For example, the reader 160 can be located immediately adjacent the cylindrical member 150 into which the pod or other container is positioned. In some embodiments, the identification tag reader 160 is configured to read and/or write to a RFID or other type of tag. However, the reader 160 can be configured to read and/or write to any other type of identification tag, as desired or required. The use of identification tags and readers could also be incorporated into any other removable portions or components of the system, such as, for example, the tips, the waste container, etc. The use of such identification systems can enhance the performance, efficiency, safety and/or other aspects related to conducting a skin treatment procedure using any of the system embodiments disclosed herein or equivalents thereof. For example, such technologies can ensure that the proper type of treatment tip (at least a portion of which will contact skin during a treatment procedure) is being used, that the proper materials will be delivered to the skin during a procedure, and/or the like.

[0117] As illustrated in FIG. 10, a pod or other container 400 can include an identification tag, e.g., RFID tag, along one or more of its surfaces or portions. In some embodiments, the pod 400 includes a flattened portion 416 that is sized, shaped and otherwise arranged to receive an automatic identification tag, such as, for example, a RFID tag or chip, a barcode, etc. Such tags can be used to advantageously store information regarding the specific pod or other treatment material container 400 that may be used in the system 10. For example, the tag can include information regarding the contents of the container, expiration date, manufacturing date, size, lot number, skin procedure with which the contents are intended to be used, other limitations or restrictions on use (e.g., counter-indications, adverse effects, other fluids with which the contents should not be combined, etc.).

[0118] The RFID or other identification tag can be read or otherwise detected (e.g., automatically, manually, etc.) by one or more readers or detectors 160 of the system. For example, as shown and discussed above, in some embodiments, the reader 160 is positioned at or near the receiving area 60 of the pod to automatically detect the identification tag of the pod once the pod has been secured to the system. Accordingly, the RFID or other type of reader 160 can advantageously detect and identify the RFID tag of the pod or other container.

[0119] According to some embodiments, the RFID or other identification tag reader 160 of the system 10 is configured to both read and write data and/or other information to the tag positioned on the pod or other container. Thus, the information included in the identification tag of the pod or other container 400 can be updated (e.g., continuously, periodically, etc. updated) by the system, as desired or required.

[0120] In circumstances where the detected identifier (e.g., whether it is from the pod or container and/or another removable/replaceable component, such as, the tip) is inconsistent with the proper, predicted, safe, appropriate and/or approved operation of the system, the system can be configured to discontinue use of the system (e.g., to prevent fluid and/or other treatment materials included within a pod or other container from being directed to the tip).

[0121] The use of the RFID or other identification tags on the pods or other containers 400 and/or other components of the system (e.g., tips) can provide one or more other advantages or benefits. The collection of data regarding use of and/or related to the corresponding container (e.g., pod) can be gathered or otherwise collected to generate reports for billing, reordering and/or other purposes. In some embodiments, the number of times that a pod can be removed and reinserted within a manifold or handpiece or handheld assembly can be limited (e.g., 1, 2, 3, 4, etc.), as desired or required. For example, such limits can help prevent or reduce the likelihood of contamination of the fluid, to prevent the incorrect treatment fluid from being used and/or to provide one or more other benefits, goals and/or advantages. In some embodiments, the automatic identification of the pod or other container being secured to the system can allow the system to determine if a rinse, flush and/or other steps or actions are required before the fluid from that container can be used and/or any other action can be taken in connection with use of the system.

[0122] According to some embodiments, the use of RFID or other identification tags can facilitate the execution of a particular skin treatment protocol by the system. For instance, the system can include various pods containing fluids necessary to carry out any one of a number of various skin treatment procedures. For example, a treatment sequence can be configured for use in procedures for periodic or normal microdermabrasion treatment, anti-aging, anti-acne, skin lightening, oily skin treatment and/or the like. Each of the sequences, protocols or modes can include the delivery of one, two or more various serums and/or other fluids or materials that are contained in the pods or other containers.

[0123] With continued reference to FIG. 8, the cylindrical member 150 can include a unique shape such that the pod or other container 400 can only be positioned within the member 150 in a particular direction or orientation. For example, as noted above, the cylindrical member 150 can include a flattened portion that corresponds to the flattened portion of the pod. This helps ensure that the RFID or other identification tag reader 160 of the system 10 will be immediately adjacent the corresponding RFID or other identification tag 416 of the pod 400 once the pod has been secured to the system.

[0124] In other embodiments, however, the pod or other container 400 need not include a flattened portion or any other unique design or feature. For example, the system can be configured to receive vials with generally continuous cylindrical bodies. Such vials or other containers can be standard or non-standard (e.g., with respect to size, diameter, other dimension, overall shape, etc.). In arrangements where identification tags are utilized, tags can be positioned along any portion of a standard or non-standard vial or container, such as, for example, the neck or top portion, along the exterior of the main cylindrical or other main portion, the bottom, etc.

[0125] As with other electrical components of the system 10, the RFID or other identification tag reader (e.g., reader/writer) can be operatively coupled to a circuit board and/or other electronics 110 of the system. Further, as discussed above, any internal electrical components of the system 10 can be operatively coupled (e.g., directly or indirectly, wirelessly or via a wired connection, etc.) to one or more internal components of the system (e.g., processors, memory, controllers, etc.) and/or external computing devices or networks (e.g., a smartphone, a tablet, a personal computer, a separate computing network, a cloud network or infrastructure, a separate skin treatment device or system, etc.) to facilitate processing of data collected by the RFID or other identification tag reader.

[0126] FIGS. 9A and 9B illustrate one embodiment of a fluid flow diagram for the skin treatment systems disclosed herein. For example, the schematic flow diagram of FIG. 9A shows the waste conduits, pathways or other lines 144, 146 that place the tip 300 in fluid communication with the liquid pump 130 and the waste container or canister 200. Further, the schematic shows the treatment fluid supply conduit or line 142 that places the pod or other container 400 in fluid communication with the tip 300.

[0127] According to some embodiments, once the tip 300 is placed against a user's skin surface and the pump 130 is activated, suction is generated along the tip and the skin surface of the subject undergoing a treatment procedure. If the tip is securely placed along the subject's skin surface, the suction force generated along the tip (by activating, e.g., a liquid pump) will help transfer fluids and/or other treatment materials from the pod 400 to the tip 300 (e.g., via the fluid delivery conduit or line 142). Thus, during operation of the system 10, waste (e.g., spent fluid, exfoliated skin tissue, etc.) can transferred from the tip 300 to the waste canister or container 200. As noted herein, the pump 130 can include a liquid pump that comes in contact (e.g., directly, at least partially, etc.) with the waste material being transferred to the waste canister 200. For example, the pump can be configured such that only certain components and/or portion of the pump actually come in direct contact with the waste being transferred to the waste container. In some arrangements, the pump can include one or more removable or replaceable components, features or portions. Such removable or replaceable components can be configured such that they are entirely, largely or at least partially responsible for coming in direct contact with waste and other materials being transferred to the waste container. In some configurations, the use of such a liquid pump (e.g., a diaphragm pump) can permit the system to operate at lower, more gentle pressure/vacuum levels to create a more pleasant and gentle skin treatment experience for the user.

[0128] In some embodiments, the pump is configured such that it is activated or initiated (e.g., automatically) once the tip or other distal portion of the system contacts skin tissue. Relatedly, the pump can be deactivated once the tip or other distal portion of the system no longer contacts skin (e.g., is lifted off the skin surface of the subject being treated). Deactivation can occur immediately or following a time delay, as desired or required. In other arrangements, the system is configured to prevent activation of the pump if contact between the system (e.g., the tip, other distal portion, etc.) and skin is not detected. In order to accomplish the foregoing, one or more sensors (e.g., contact sensors, pressure sensors, temperature sensors, etc.) can be positioned at or near the tip or other distal portion of the system.

[0129] FIG. 9B illustrates, in cross-sectional view, one embodiment of a skin treatment system 10. The various internal components of the system 10, including the fluid conduits or lines 142, 144, 146, the pump 130, the waste canister or container 200, the tip 300 and the pod or other container 400 can be seen with representation of fluid flow using arrows. At least a portion of the illustrated internal configuration can be incorporated into any of the system embodiments disclosed herein or equivalents thereof.

[0130] With continued attention to FIG. 9B, activation of one or more pumps or other fluid transfer devices of the system can generate a vacuum or suction force along the tip or other distal portion 300 of the system. As a result of such vacuum or suction along or near the tip, fluid conduits, pathways or other lines hydraulically coupling the tip or distal end 300 with a fluid pod or container 400 can transfer serums, fluids and/or other materials from the interior of the pods or other containers secured to the system to and/or near the tip or distal end. Spent fluids or other treatment materials, exfoliated skin tissue, materials removed from the skin surface being treated (e.g., oils, sebum, blackheads, etc.) and/or other waste materials can be transferred from the tip or distal end 300 of the system to a waste container 200.

[0131] The embodiment illustrated in FIG. 9B and discussed above is only one configuration of the system's hydraulic network, which includes one or more of the following: fluid conduits, pumps, valves, etc. Alternative ways of transferring treatment material to the tip or other working end and/or removing spent fluids and waste materials from the tip or other working end can be incorporated into any of the embodiments of the system disclosed herein or equivalents thereof.

[0132] As noted above, FIG. 10 illustrates one embodiment of a pod or other container 400 configured to be used in the skin treatment system 10. The pod 400 can include a main container portion 410 for containing or housing the serum or other treatment fluid or material. The main container portion 410 can include a tag or label 410. Further, as discussed above, the main container portion 410 can include a flattened or other unique area or portion 416 that is sized, shaped and otherwise adapted to receive a RFID or other identification tag. The container can include a RFID and/or any other type of identification tag or feature along any portion or area (e.g., at, near or along the neck 432 and/or cap 434, its main container portion 410, its bottom portion, etc.), as desired or required. Such tags can be permanently secured to the pod or other container. However, in alternative embodiments, the tags are removably secured to the pod or container, as desired or required.

[0133] With further reference to FIG. 10, the pod 400 can include an upper portion 430 that extends from or adjacent the main container portion 410. The upper portion 430 can include a neck 432 and a cap 434. In some embodiments, the cap 434 includes a septum, membrane or other penetrable member 438 along its upper surface 436. As noted herein, such a member 438 can be penetrated or otherwise accessed to selectively place the internal contents of the pod or other container 400 in fluid communication with the system (e.g., fluid delivery conduit, the tip, etc.) once the pod 400 is secured to the receiving area of the system.

[0134] According to some embodiments, placement of a pod or other container 400 within the designated recess, slot or other opening of the system aligns the septum or other portion of the pod or container configured to be penetrated or otherwise compromised (e.g., to access the internal contents contained within the pod) with a spike or other protruding member of the system. This can place the contents of the pod or container with one or more fluid conduits, pathways and/or other hydraulic features or components of the system to enable the contents to be selectively delivered to the tip or other distal end of the system.

[0135] FIGS. 11A and 11B illustrate different side views of the pod 400 of FIG. 10. Further, FIGS. 12A and 12B illustrates front and rear views of the pod 400 of FIG. 10. Finally, FIGS. 13A and 13B illustrate top and bottom views of the pod 400 of FIG. 10.

[0136] FIGS. 14 to 17 illustrate a tip 300 configured to be secured to and used with any of the skin treatment embodiments disclosed herein (e.g., the skin treatment system 10 of FIG. 1). As shown, the tip 300 can include a top or distal end 302 and a bottom or proximal end 304. In some embodiments, the tip 300 is configured to secure to the tip receiving area 50 (FIG. 7B) of the main body portion 20. As shown, the tip can include a fluid delivery structure 320 that defines a fluid delivery passage 322 through which serums and/or other treatment materials (e.g., from the pod 400) can flow toward the distal end 302 of the tip. In some embodiments, the fluid delivery structure 320 extends proximally (e.g., past the remaining portions of the tip) in order to facilitate securement of the tip to the main body portion to the tip receiving area 50.

[0137] As depicted in FIG. 17, the rollerball can be secured within the rollerball housing structure 330 by a series of vanes 334 along its proximal end and one or more retaining lips or members 338 along the distal end. Accordingly, the rollerball 350 can be maintained within the structure 330 and permitted to selectively turn or rotate during use. For example, the rollerball 350 and the adjacent surfaces of the rollerball housing structure 330 can be configured to permit the rollerball to rotate when the rollerball 350 contact skin tissue and is moved relative to said skin tissue. Further, the inclusion of vanes 334 or similar structures along the proximal end of the rollerball 350 can help maintain additional moisture from the treatment fluid along the rollerball during use.

[0138] In other embodiments, the tip illustrated in FIGS. 14 to 17 can be modified to exclude a rollerball or similar component or feature. In some embodiments, one or more abrasive structures or portions can be provided in the area where the rollerball is depicted in the illustrated embodiments. Therefore, in such arrangements, the tip can include one or more protrusions, recesses and/or other non-planar features along one or more of its portions or areas.

[0139] With continued reference to FIGS. 14 and 17, the tip 300 comprises a rollerball 350 that is securely positioned within a rollerball housing structure 330. As illustrated, the rollerball 350 is placed in fluid communication with the fluid delivery passage 322 of the fluid delivery structure 320. Accordingly, serums and/or other treatment liquids or materials passing through passage 322 can be directed to the rollerball 350. In some embodiments, the rollerball is solid and comprises one or more metals and/or alloys. For instance, the rollerball can include a solid stainless steel construction. However, in other embodiments, the rollerball 350 can be at least partially hollow (e.g., not solid). Further, the rollerball 350 can include any other type of metal or alloy and/or other material, as desired or required.

[0140] With reference to the top view of the tip 300 illustrated in FIG. 15A, the tip 300 can include a peripheral lip 310 that extends along the outer perimeter along the distal end 302 of the tip. The peripheral lip 310 can be sized, shaped and otherwise configured to contact skin tissue when the skin treatment system 10 is being used. As discussed herein, in some embodiments, the activation of the fluid pump 130 of the system helps create sufficient suction or vacuum along the distal end of the tip so that the peripheral lip 310 can engage tissue during a treatment procedure. This can occur despite the fact that, in some embodiments, such as those illustrated herein, the rollerball extends distally past the distal-most portion of the peripheral lip 310. Thus, in some arrangements, once the liquid pump of the system is activated, the vacuum or suction created along the distal end 302 of the tip 300 can help form at least a partial seal between the peripheral lip 310 of the tip 300 and the skin surface of the subject undergoing a treatment procedure.

[0141] As noted above, in some embodiments, the rollerball 350 is sized, shaped and otherwise configured within the tip to extend distally past the distal most portion of the peripheral lip 310. In some arrangements, the rollerball extends 0.8 to 1 mm (0.8 mm to 0.85 mm, 0.85 mm to 0.9 mm, 0.9 mm to 0.95 mm, 0.95 to 1 mm, 0.7 mm to 1 mm, 0.7 mm to 1.2 mm, 0.5 mm to 1.5 mm, less than 0.5 mm, more than 1.5 mm, values between the foregoing, etc.) distally past the peripheral lip 310. According to some embodiments, the rollerball 350 to extend distally past the distal most portion of the peripheral lip by 0.1% to 30% (e.g., 0.1 to 1, 1 to 5, 5 to 10, 10 to 15, 15 to 20, 20 to 25, 25 to 30, 0.1 to 5, 0.1 to 10%, values between the foregoing ranges, greater than 30%, less than 0.1%, etc.) of the diameter or other cross-sectional dimension of the rollerball.

[0142] With the application of vacuum along the distal end 302 of the tip (e.g., via activation of the fluid pump of the system), the delivery of treatment fluid from the pod via the fluid delivery conduit, the passage 322 and the rollerball/rollerball housing structure 330 can be enhanced. The arrow 326 in the cross-sectional view of FIG. 17 schematically illustrates the direction of fluid flow through the tip.

[0143] With further attention to FIGS. 14, 15A and 17, the tip 300 can additionally include at least one interior baffle or wall 316. Such a baffle or wall 316 can prevent or reduce the likelihood of the short-circuiting of fluid passing through the rollerball 350 to the distal end 302 of the tip 300. In other words, the baffle or wall 316 can create a more tortious pathway of fluid from the rollerball (e.g., fluid passing around the rollerball 350) to the one or more waste ports or outlets 342. FIG. 15A schematically illustrates using arrow 360 fluid passing around the baffle or wall 316 to reduce the amount of flow circuiting of treatment fluid making its way to the distal end 302 of the tip 300. This can advantageously increase the contact time between the treatment fluid and the skin surface being treated during a procedure, thereby enhancing the effectiveness of the procedure.

[0144] With continued reference to FIG. 17, waste materials (e.g., spent fluid, skin debris, etc.) can be directed through one or more waste ports or openings 342 and removed from the tip 300 using the vacuum or suction force generated by the pump (e.g., liquid pump). As noted herein, such waste can be transferred from the tip 300 to the waste canister or container 200 using the waste fluid network, 144, 146 and the pump.

[0145] According to some embodiments, the tips 300 include one or more plastic materials. In some arrangements, the tips 300 are at least partially translucent or transparent. In some embodiments, the tips 300 are disposable. However, in other arrangements, the tips 300 can be reusable, as desired or required.

[0146] As illustrated in FIGS. 14 to 17, the tips can include angled side walls 308. The angles side walls 308 can assist with enhancing the overall look and feel of the treatment system 10 once the tips are secured thereto. For example, as illustrated in FIG. 1, the side slopes of the tip can create a smoother overall look for the assembled system 10.

[0147] With continued attention to FIG. 17, the top or distal portion of the tip 300 can be angled relative to a plane P perpendicular to the longitudinal axis of the tip 300 (and the system 10). Such an angle Θ can assist with manipulating the system 10 during use. For example, the angle of the tip 300 can permit the user to tilt the entire system 10 during use provide for a more ergonomic and comfortable execution of a skin treatment procedure. According to some embodiments, the angle Θ is between 2 and 10 degrees (e.g., 2 to 3, 3 to 4, 4 to 5, 5 to 6, 6 to 7, 7 to 8, 8 to 9, 9 to 10, 2 to 5, 5 to 8, 8 to 10 degrees, angles between the foregoing ranges and values, etc.). However, in other embodiments, the angle Θ is less than 2 degree or greater than 10 degrees, as desired or required.

[0148] In some embodiments, the peripheral lip and/or the internal baffle or wall can be configured to at least partially abrade skin tissue as the system 10 is moved (e.g., translated) relative to a subject's skin tissue. The abrasion can be enhanced with relatively higher suction forces applied by the pump (e.g., liquid pump) to the tip.

[0149] According to some embodiments, the various embodiments of a skin treatment system disclosed herein can be self-administered by a user on his or her own (e.g., at home). Such a skin treatment protocol can be a stand-alone procedure to improve the skin health of a subject. However, in other embodiments, the skin treatment embodiments disclosed herein are intended to be used in conjunction with a larger skin treatment regimen that includes periodic professional treatments (e.g., by an aesthetician or other skin treatment professional). For instance, in some arrangements, the skin treatment systems described herein can be used once or twice (or more often) between visits to a skin treatment professional.

[0150] According to some embodiments, the skin treatment system 10 disclosed herein can include different treatment steps or phases. For example, in one arrangement, the first step includes a cleansing step. This can be followed up by a secondary hydration step. In some embodiments, additional steps or phases can be used. In some embodiments, different pods can be used for various steps or phases. Therefore, the user may need to remove a first pod or treatment material container 400 from the system and replace with a different one, and vice versa, as desired or required.
