Abstract

An endoluminal prosthesis comprises a prosthetic trunk having a trunk lumen and a trunk wall, a first prosthetic branch having a first branch lumen and a branch wall, and a second prosthetic branch having a second branch lumen. The first branch lumen and the second branch lumen are both in fluid communication with the trunk lumen through the trunk wall and the second branch lumen is in fluid communication with the first branch lumen through the branch wall. Additional devices, systems, and methods are disclosed.

Claims

1. An endoluminal prosthesis comprising:

a prosthetic trunk comprising a trunk lumen extending therethrough and a trunk wall;

a first prosthetic branch extending from the trunk wall and comprising a first branch lumen extending therethrough and a branch wall;

a second prosthetic branch extending from the branch wall and comprising a second branch lumen extending therethrough;

where the first branch lumen and the second branch lumen are both in fluid communication with the trunk lumen through the trunk wall; and

where the second branch lumen is in fluid communication with the first branch lumen through the branch wall.

2. The prosthesis of claim 1, where at least one of the prosthetic branches is disposed longitudinally along and circumferentially about the prosthetic trunk.

3. The prosthesis of claim 1, where both the first prosthetic branch and the second prosthetic branch are disposed longitudinally along and circumferentially about the prosthetic trunk.

4. The prosthesis of claim 1, where the second prosthetic branch is disposed longitudinally along and circumferentially about the first prosthetic branch.

5. The prosthesis of claim 1, where the first prosthetic branch is tapered along its length.

6. The prosthesis of claim 1, further comprising any two or more of the following:

the first prosthetic branch is disposed longitudinally along and circumferentially about the prosthetic trunk;

the second prosthetic branch is disposed longitudinally along and circumferentially about the prosthetic trunk;

the second prosthetic branch is disposed longitudinally along and circumferentially about the first prosthetic branch; and

the first prosthetic branch is tapered along its length.

7. An endoluminal prosthesis comprising:

a prosthetic trunk comprising a trunk lumen extending therethrough, a wall, and an anastomosis in the wall;

a stent attached to the prosthetic trunk adjacent the anastomosis, where the stent comprises a generally tubular stent body that provides radial support to the prosthetic trunk, where the stent body alternates endlessly about a longitudinal axis of the prosthetic trunk between a first stent pattern and a second stent pattern;

where the first stent pattern comprises a loop having a contour that contacts and supports the entire perimeter of the anastomosis.

8. The prosthesis of claim 7, where the second stent pattern has a generally zigzag shape.

9. The prosthesis of claim 7, where the loop comprises an ovoid shape.

10. An endoluminal prosthesis comprising:

a prosthetic trunk comprising a trunk lumen extending therethrough;

a prosthetic branch comprising a branch lumen extending therethrough;

a stent having a stent pattern that alternates endlessly about the perimeter of the stent between a first tubular stent region disposed about a first axis and a second tubular stent region disposed about a second axis;

where the first stent region is attached to and supports at least a portion of the prosthetic trunk and the second stent region is attached to and supports at least a portion of the prosthetic branch.

11. The prosthesis of claim 10, where the stent pattern includes a generally zigzag shape.

12. The prosthesis of claim 10, where the first stent region has a different diameter than the second stent region.

13. The prosthesis of claim 10, where the first stent axis is generally collinear with the second stent axis.

14. The prosthesis of claim 10, where the prosthetic branch is disposed, at least in part, inside the prosthetic trunk lumen.

15. The prosthesis of claim 10, where the prosthetic branch is disposed, at least in part, outside the prosthetic trunk lumen.

16. The prosthesis of claim 10, where the stent has a figure-8 shape.

17. The prosthesis of claim 10, where at least a portion of the first stent region is disposed on an interior surface of the prosthetic trunk.

18. The prosthesis of claim 17, where at least a portion of the first stent region is disposed on an exterior surface of the prosthetic branch.

19. The prosthesis of claim 10, where at least a portion of the second stent region is disposed on an exterior surface of the prosthetic branch.

20. The prosthesis of claim 10, further comprising any two or more of the following:

The stent pattern includes a generally zigzag shape;

the first stent region has a different diameter than the second stent region;

the first stent axis is generally collinear with the second stent axis;

the prosthetic branch is disposed, at least in part, inside the prosthetic trunk lumen;

the prosthetic branch is disposed, at least in part, outside the prosthetic trunk lumen;

the stent has a figure-8 shape;

at least a portion of the first stent region is disposed on an interior surface of the prosthetic trunk;

at least a portion of the first stent region is disposed on an exterior surface of the prosthetic branch; and

at least a portion of the second stent region is disposed on an exterior surface of the prosthetic branch.
