- 12. The prosthesis of claim 1, wherein the branch lumen is disposed longitudinally and circumferentially inside the prosthetic trunk.
- 13. The prosthesis of claim 1, wherein the prosthetic branch is attached at a point on the prosthetic trunk that is distal to the anastomosis.
- 14. The prosthesis of claim 13, wherein the prosthetic branch is attached at multiple points on the prosthetic trunk that are distal to the anastomosis.
- 15. The prosthesis of claim 1, wherein the prosthetic branch is attached at a point on the prosthetic trunk that is proximal to the anastomosis.
- 16. The prosthesis of claim 15, wherein the prosthetic branch is attached at multiple points on the prosthetic trunk that are proximal to the anastomosis.
- 17. The prosthesis of claim 1, wherein the prosthetic branch comprises a proximal ostium and a distal ostium.
- 18. The prosthesis of claim 17, wherein the proximal ostium is infundibular.
- 19. The prosthesis of claim 17, wherein the diameter of the proximal ostium of the prosthetic branch is larger than the distal ostium of the prosthetic branch.
- 20. The prosthesis of claim 17, wherein the distal ostium is beveled.
- 21. The prosthesis of claim 1, further comprising a second prosthetic branch having a second branch lumen extending therethrough, wherein the second branch lumen is in fluid communication with the trunk lumen through a second anastomosis and wherein the second prosthetic branch is disposed longitudinally and circumferentially about the prosthetic trunk.
- 22. The prosthesis of claim 8, further comprising a second prosthetic branch having a second branch lumen extending therethrough, wherein the second branch lumen is in fluid communication with the trunk lumen through a second anastomosis and wherein the second prosthetic branch is disposed longitudinally and circumferentially about the prosthetic trunk.
- 23. The prosthesis of claim 22, wherein both prosthetic branches shunt blood distally relative to the prosthetic trunk.
- 24. The prosthesis of claim 1, further comprising a branch extension connected to and in fluid communication with the prosthetic branch.
- 25. The prosthesis of claim 2, wherein the prosthetic branch has an angle of access that is greater than 20°.
- 26. The prosthesis of claim 25, wherein the angle of access is greater than 60°.
- 27. The prosthesis of claim 2, wherein the prosthetic branch is skewed between about 40° and about 60°.
- 28. The prosthesis of claim 2, wherein the prosthetic branch is skewed between about 0° and about 40°.
- 29. The prosthesis of claim 2, wherein the prosthetic branch has an angle of incidence that is between about 20° and about 60°.
- 30. The prosthesis of claim 29, wherein the prosthetic branch has an angle of incidence that is between about 35° and about 50°.
- 31. A method of connecting modules of an endoluminal prosthesis, comprising:
providing a prosthetic trunk; providing a prosthetic branch having proximal and distal ends; anastomosing the proximal end of the prosthetic branch to the prosthetic trunk; and positioning the prosthetic branch and attaching the prosthetic branch to the prosthetic trunk so as to provide a helical fluid passage.
- 32. A method of increasing the angle of access for an endoluminal prosthesis, comprising:
providing a prosthetic trunk comprising a trunk lumen extending therethrough, a wall and an anastomosis in the wall; and providing a prosthetic branch having a branch lumen extending therethrough, wherein the branch lumen is in fluid communication with the trunk lumen through the anastomosis and disposed longitudinally and circumferentially about the trunk lumen.
