Abstract

An endoluminal prosthesis comprises a prosthetic trunk comprising a trunk lumen extending therethrough, a wall, an anastomosis in the wall, and a first fenestration in the wall, wherein the prosthetic trunk has a circumference. The endoluminal prosthesis further comprises a prosthetic branch comprising a branch lumen extending therethrough. The branch lumen is in fluid communication with the trunk lumen through the anastomosis. The prosthetic branch is disposed longitudinally along and circumferentially about the prosthetic trunk.

Claims

1. An endoluminal prosthesis, comprising:

a prosthetic trunk, wherein the prosthetic trunk comprises a trunk lumen extending therethrough, a wall, a first fenestration in the wall, and an anastomosis; and

a first prosthetic branch comprising a branch lumen extending therethrough, wherein the branch lumen is in fluid communication with the trunk lumen through the anastomosis, and wherein the prosthetic branch is disposed longitudinally along and circumferentially about the prosthetic trunk.

2. The prosthesis of claim 1, further comprising a second prosthetic branch disposed longitudinally along and circumferentially about the prosthetic trunk.

3. The prosthesis of claim 2, further comprising a third prosthetic branch disposed longitudinally along and circumferentially about the prosthetic trunk.

4. The prosthesis of claim 1, further comprising a second fenestration.

5. The prosthesis of claim 4, further comprising a third fenestration.

6. The prosthesis of claim 1, wherein the first prosthetic branch is disposed longitudinally along and circumferentially about an internal surface of the prosthetic trunk.

7. The prosthesis of claim 1, wherein the first prosthetic branch is disposed longitudinally along and circumferentially about an external surface of the prosthetic trunk.

8. The prosthesis of claim 1, wherein the first prosthetic branch shunts blood distally relative to the prosthetic trunk.

9. The prosthesis of claim 1, wherein the first prosthetic branch shunts blood proximally relative to the prosthetic trunk.

10. The prosthesis of claim 1, wherein the prosthetic trunk is curved for deployment within the thoracic aorta.

11. The prosthesis of claim 1, further comprising an extension module forming a tromboning connection with the first prosthetic branch.

12. The prosthesis of claim 1, wherein the first prosthetic branch is disposed circumferentially about at least a portion of the posterior side of the prosthetic trunk.

13. The prosthesis of claim 1, wherein the first prosthetic branch is disposed circumferentially about at least a portion of the anterior side of the prosthetic trunk.

14. The prosthesis of claim 1, further comprising:

a second prosthetic branch disposed longitudinally along and circumferentially about an anterior outside surface of the prosthetic trunk;

a second fenestration; and

an extension module forming a tromboning connection with the first prosthetic branch;

wherein the first prosthetic branch shunts blood distally relative to the prosthetic trunk.

15. An endoluminal prosthesis, comprising:

a prosthetic trunk, wherein the prosthetic trunk comprises a trunk lumen extending therethrough, a wall, and an aperture in the wall;

a prosthetic branch comprising a branch lumen extending therethrough, wherein the branch lumen is in fluid communication with the trunk lumen, wherein the prosthetic branch is disposed longitudinally along and circumferentially about an internal surface of the prosthetic trunk, and wherein the prosthetic branch extends through the aperture in the wall; and

at least one baffle attached to a length of the first prosthetic branch.

16. An endoluminal prosthesis, comprising:

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

a prosthetic branch comprising a branch lumen extending therethrough, wherein the branch lumen is in fluid communication with the trunk lumen through the anastomosis;

wherein the anastomosis comprises a tail for accommodating a guide wire.

17. An endoluminal prosthesis, comprising:

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

a first prosthetic branch comprising a first branch lumen extending therethrough, wherein the first branch lumen is in fluid communication with the trunk lumen through an anastomosis, and wherein the first prosthetic branch is disposed in a proximal direction along and circumferentially about the prosthetic trunk;

a second prosthetic branch comprising a second branch lumen extending therethrough, wherein the second branch lumen is in fluid communication with the trunk lumen through an anastomosis, and wherein the second prosthetic branch is disposed in a proximal direction along and circumferentially about the prosthetic trunk; and

a third prosthetic branch comprising a third branch lumen extending therethrough, wherein the third branch lumen is in fluid communication with the trunk lumen through an anastomosis.

18. A thoracic endoluminal prosthesis, comprising:

a prosthetic thoracic trunk, wherein the prosthetic thoracic trunk comprises a trunk lumen extending therethrough, a wall, and an anastomosis in the wall;

a prosthetic branch comprising a branch lumen extending therethrough, wherein the branch lumen is in fluid communication with the trunk lumen through the anastomosis; and

at least one bellows formed in the prosthetic thoracic trunk.

19. An endoluminal prosthesis, comprising:
