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 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, a torque catheter and a stub nose balloon catheter, comprising the steps of:

performing a surgical technique to gain remote access to each branch of the bifurcated vessel;

advancing the multicapsule catheter within a first branch of the bifurcated vessel;

configuring the first capsule of the multicapsule catheter in a position distal to the bifurcation;

configuring the second capsule of the multicapsule catheter in the first branch of the bifurcated vessel;

configuring the third capsule of the multicapsule catheter in the second branch of the bifurcated vessel;

releasing the first capsule from the graft;

advancing the torque catheter within the second branch of the bifurcated vessel until the torque catheter engages the third capsule;

removing any undesirable regularities in the graft residing in the second branch of the bifurcated vessel;

releasing the third capsule from the graft;

releasing the second capsule from the graft; and

withdrawing the multicapsule catheter and the torque catheter from the repair cite.

2. The method of claim 1, further comprising the steps of:

advancing the stub nose balloon catheter within the second branch of the bifurcated vessel; and

expanding the stub nose balloon catheter to secure the graft within the second branch of the bifurcated vessel.

3. The method of claim 1, further comprising the step of:

pulling the second capsule of the multicapsule catheter proximally subsequent to releasing the first capsule so that the graft is deployed in tension.

4. The method of claim 1, further comprising the step of:

pulling the third capsule of the multicapsule catheter proximally subsequent to releasing the first capsule so that the graft is deployed in tension.

5. The method of claim 1, further comprising the step of:

advancing the second capsule of the multicapsule catheter distally subsequent to releasing the first capsule so that the graft is deployed in compression.

6. The method claim 1, further comprising the step of:

advancing the third capsule of the multicapsule catheter distally subsequent to releasing the first capsule so that the graft is deployed in compression.

7. The method of claim 1, wherein the system further includes an elongate balloon catheter and further comprising the step of expanding the elongate balloon catheter to secure the portion of the graft positioned distal to the bifurcation within the vessel.

8. The method of claim 7, further comprising the step of expanding the elongate balloon catheter to secure the portion of the graft positioned within the first branch of the bifurcated vessel within the vessel.
