The guide line component 11 illustrated in FIG. 7 has a circular profile 114. The circular profile 114 may have a solid construction. A hollow or tubular construction having a central aperture 1140, shown in phantom, is also considered to be well within the scope of the present invention.

[00053] In accordance with embodiments of the present invention, the distal end of the guide line component 11 may have a linear orientation, as shown in FIG. 11. Alternatively, the distal end of the guide line component 11 may have a bent configuration 41, as shown in FIG. 12. The distal end of the guide line component 11 may be articulated to facilitate manipulation of the guide line assembly 10 within the vessel for positioning a surgical component such as for example a repair graft assembly 2, as shown in FIG. 13. In this embodiment, the guide line component 11 includes an articulated segment 31 located adjacent the distal end. The articulated segment 31 may be manually adjusted by the surgeon. It, however, is contemplated that the articulated segment 31 may be remotely adjusted using the hand controller 2 or other suitable manipulation assembly.

[00054] The operation of the guide line assembly 10 will now be described in connection with a repair graft assembly 2. It, however, is contemplated by the inventors of the present invention that the guide line assembly 10 may be used with other surgical components for use in other intravascular procedures. The guide line assembly 10 is secured to the repair graft assembly 2. Specifically, the surgical needle 13 is inserted through the lip of the repair graft assembly 2. The surgical needle 13 is then looped around the suture 12 to secure the guide line assembly 10 to the repair graft assembly 2. The surgical needle 13 is then removed. The repair graft 2 can then be inserted and maneuvered within the vessel. The positioning of the repair graft 2 within the vessel can be adjusted using the hand controller 2.

[00055] The guide line assembly 20 according to another embodiment of the present invention, depicted in FIG. 14, will now be described in greater detail. Guide line assembly 20 includes a guide line component 21. The guide line component 21 is fairly stiff. The guide line component 21 has a distal end which is located within the vessel during the surgical procedure and a proximal end which extends from within the vessel. The guide line assembly 20 is manipulated within the vessel adjacent the proximal end of the guide line component 21. The guide line assembly 20 further includes at least one suture 22 connected to the guide line component 21. The at least one suture 22 is secured to one end of the guide line component 21. The guide line component 21 has sufficient length such that it may extend from within the vessel caudad to the femoral incision and thereafter to a hand controller as shown in FIG. 1 in connection with guide line assembly 10. The guide line component 21 is preferably formed from nitonol. It, however, is contemplated that the guide line component 11 may be formed from a similar biocompatible material.

[00056] At least one suture 22 is secured to the guide line component 21. The embodiment of the present invention illustrated in FIG. 14 includes a pair of sutures 22. The present invention, however, is not limited to a single suture 22. It is contemplated that more than one suture 22 may be used. The suture 22 is mechanically coupled to the distal end of the guide line component 21. For example, the at least one suture 22 may be bonded and/or crimped to the end of the guide line component 21. Other forms of coupling, however, are considered to be well within the scope of the present invention. The guide line assembly 20 according to embodiments of the present invention includes a surgical needle assembly 23 secured to one end of the suture 22. The provision of the surgical needle assembly 23 facilitates the attachment of the guide line assembly 10 to a repair graft assembly 20 or other suitable surgical component within the vessel. The distal end of the guide line assembly 20 may be curved, as shown in FIG. 14. A broad line assembly 24 surrounds the suture 22 adjacent the distal end of the guide line component 21. The broad line assembly 24 permits the distal end of the guide line assembly 20 to retain its curved shape. The broad line assembly 24 is preferably flexible. It is preferably formed from a spring type material. The end of the guide line component 21 and the suture 22 may be coated and/or sheathed with a thin layer 25 of Gore-Tex® or other suitable material. The thin layer 25 prevents the curved end portion of the guide line assembly 20 from snagging when it is manipulated within the vessel and/or removed from the vessel.

[00057] A guide line assembly 50 according to another embodiment of the present invention is illustrated in FIG. 15. The guide line assembly 50 includes a guide line component 51, which is fairly stiff. The component 51 may be formed from a thin metal rod or needle. The component 51 has a distal end that is located within the vessel during the surgical procedure and a proximal end that extends from within the vessel. The guide line assembly 50 further includes at least one suture 52 secured to the distal end of the component 51. A surgical needle assembly 53 is secured to one end of the suture 52. The surgical needle assembly 53 may be straight or curved, as shown in FIG. 15.

[00058] During a surgical procedure, it is possible that several guide line assemblies, described above, may be located within the vessel. It is possible that during the surgical procedure these guide line assemblies and sutures may become entwined, which may hamper the surgical procedure. Therefore, it is desirable to provide an assembly that is capable of separating any entwined guide line assemblies and sutures. A suture and guide line separator assembly 60 will now be described in connection with FIGS. 16 and 17. The separator assembly 60 includes a catheter assembly 61. One end of the catheter assembly 61 includes a separating assembly 62 connected thereto. The separating assembly 62 is capable of rotating about the axis of the catheter assembly 61. The separating assembly 62 includes a plurality of opening 621 are sized to receive a guide line assembly or a suture therein. An opposite end of the catheter assembly 61 includes a handle assembly 63. The handle assembly 63, when compressed, locks the separating assembly 62 in place such that it cannot rotate about the axis of the catheter assembly 61.

[00059] The operation of the separator assembly 60 will now be described. The free ends of the suture and guide line assemblies are threaded through the openings 621 in the separating assembly 62. The separator assembly 60 is advanced within the vessel along the sutures and guide line assemblies. The free ends of the sutures and the guide line assemblies located outside the vessel are preferably held in place to prevent insertion into the vessel while the separator assembly 60 is advanced to its furthest most position within the vessel. While the separator assembly 60 is advanced, the separating assembly 62 freely rotates about the catheter assembly 61. Once the separator assembly 60 reaches its furthest position within the vessel, the handle assembly 63 is operated to lock the separating assembly 62 to prevent its rotation. The separator assembly 60 may then be withdrawn from the vessel during which time the sutures and guide line assemblies may be straightened out and untangled. It is contemplated that the separator assembly 60 may be used in connection with any of the above described guide line assemblies. It is further contemplated that the separator assembly 60 may be used to separate sutures or a combination of sutures and guide line assemblies. It is further contemplated that the separator assembly 60 may be used in connection with any other surgical component that is capable of being entangled within a vessel during a surgical procedure.

[00060] It is further contemplated that the separator assembly 60 may be used to position and rotate a graft assembly 7 within the vessel, as shown in FIG. 18. A single suture 5 may be fed through two openings 621 in the separating assembly 62 and loops 71 on the graft assembly 7. The graft assembly 7 may be advanced into position within the vessel by inserting the separator assembly 60 into the vessel. As the separator assembly 60 is inserted, the graft assembly 7 and the separating assembly 62 will rotate freely about the axis of the catheter assembly 61. When the graft assembly 7 reaches the desired location, the handle assembly 63 is operated to prevent rotation of separating assembly 62. The catheter assembly 61 may then be rotated to position the graft assembly 7 in the desired location.

[00061] It will be apparent to those skilled in the arts that various modifications and variations can be made in the construction and configuration of the present invention, without departing from the scope or spirit of the invention. It is intended that the present invention cover the modifications and variations of the invention, provided they come within the scope of the appended claims and their equivalence.
