Abstract

An apparatus and method for repairing a vessel at a bifurcation using a multicapsule catheter having first, second and third capsules for releasably retaining each terminal end of a bifurcated graft. The method for repairing the vessel includes the steps of performing a surgical technique to gain remote access to the vessel, advancing the multicapsule catheter within the vessel and releasing the bifurcated graft within the vessel to thereby repair the vessel.

Claims

1. A device for reorienting a graft at least partially implanted within vasculature, comprising:

an elongate shaft having first and second end portions; and

a releasable connection device attached to said first end portion, said releasable connection device configured to be operatively attached to the graft at least partially implanted within vasculature;

wherein said second end portion is configured to be manipulated by an operator to effect reorientation of the graft.

2. The reorienting device of claim 1, said shaft further comprising a through lumen.

3. The reorienting device of claim 2, said second end portion further comprising a hemostatic seal.

4. The reorienting device of claim 3, wherein said shaft is configured with a plurality of purge ports in fluid communication with said through lumen.

5. The reorienting device of claim 2, wherein the graft is attached to a catheter assembly.

6. The reorienting device of claim 5, wherein said through lumen is adapted to receive said catheter assembly and said releasable connection device is adapted to releasably engage a portion of said catheter assembly.

7. The reorienting device of claim 1, wherein said releasable connection device is a barb adapter.

8. The reorienting device of claim 1, wherein said releasable connector device is a radiopaque adapter.

9. The reorienting device of claim 1, said first end portion further comprising a radiopaque marker.

10. The reorienting device of claim 1, said second end portion further comprising a stop cock and a luer fitting.

13. The method of claim 1, further comprising the step of applying a torque to the second end portion.

11. A method for reorienting a graft at least partially implanted within vasculature using an elongate reorienting device having a first end portion configured with a releasable connection device and a second end portion configured to be manipulated by an operator, comprising the steps of:

advancing the reorienting device within vasculature to a site proximate the graft;

causing the first end portion to become operatively connected to the graft; and

manipulating the second end portion to reorient the graft.

12. The method of claim 11, wherein the reorienting device includes a through lumen and a catheter assembly is attached to the graft, further comprising the steps of:

advancing the reorienting device over said catheter assembly; and

causing the first end portion to releasably engage the catheter assembly.

14. The method of claim 11, wherein the first end portion further includes a radiopaque marker and further comprising the step of observing positioning of the reorienting device within vasculature by fluoroscopy.

15. The method of claim 12, wherein the second end portion is configured with a stop cock and the reorienting device is further configured with a plurality of purge ports, further comprising the step of injecting contrast fluid through the through lumen.
