Abstract

A stent graft adapted to telescopically receive a secondary stent graft characterized in that the stent graft comprises at least one socket communicating with at least one opening in the stent graft. The at least one socket comprises an elastic wall that forms a lumen with a stent at least partially encased within the wall. The socket can be adapted for use with stent grafts for implantantation in an aneurysm.

Claims

1. A stent graft for endoluminal implantation, wherein the stent graft is adapted to telescopically receive a secondary stent graft, characterized in that the stent graft comprises at least one socket communicating with at least one opening in the stent graft, the at least one socket comprising an elastic wall forming a lumen with a stent at least partially encased within the wall.

2. The stent graft of claim 1 wherein the at least one socket comprises a proximal end and the proximal end flares around the at least one opening in the stent graft.

3. The stent graft of claim 1 wherein the at least one socket has an expandable diameter.

4. The stent graft of claim 1 wherein the at least one socket is tapered.

5. The stent graft of claim 1 wherein the at least one socket further comprises reinforcing elements comprising nitinol or polyethylene fibers.

6. The stent graft of claim 1 wherein the at least one socket extends radially from the stent graft at an acute, right, or obtuse angle.

7. The stent graft of claim 1 wherein the at least one socket is attached to the stent graft by repolymerization or is thermoformed.

8. The stent graft of claim 1 wherein the at least one socket comprises radiopaque markers.

9. The stent graft of claim 1 wherein the at least one socket is comprised of polyurethane or ePTFE.

10. The stent graft of claim 1 wherein the stent graft is suitable for placement in an abdominal aortic aneurysm or a thoracic aortic aneurysm.

11. The stent graft of claim 1 wherein the at least one opening corresponds to a renal artery and the at least one socket is adapted for receiving a secondary stent graft extending into a renal artery.

12. The stent graft of claim 1 further comprising a second socket in communication with a second opening in the stent graft.

13. The stent graft of claim 1 wherein the stent graft further comprises a reinforcing ring around the opening and the stent is attached to the reinforcing ring while at least partially encased within the wall of the at least one socket.

14. The stent graft of claim 1 wherein the stent graft is adapted for placement in the aortic arch.

15. The stent graft of claim 1 wherein the at least one opening corresponds to a branch artery in the aortic arch and the at least one socket is adapted for receiving a secondary stent graft extending into the branch artery.

16. The stent graft of claim 1 comprising two sockets.

17. The stent graft of claim 1 further comprising a secondary socket for receiving a secondary stent graft comprising an elastic wall forming a lumen.

18. A stent graft for endoluminal implantation, wherein the stent graft is bifurcated with two distal openings and is adapted to telescopically receive a secondary stent graft, characterized in that the stent graft comprises at least one socket communicating with at least one opening in the stent graft, the at least one socket comprising an elastic wall forming a lumen with a stent at least partially encased within the wall and is adapted to telescopically receive a secondary stent graft.

19. The stent graft of claim 18 further comprising a socket proximal to the bifurcation, the socket comprising an elastic wall forming a lumen with a stent at least partially encased within the wall.

20. The stent graft of claim 18 wherein the at least one socket telescopically receives a secondary stent graft extending into an iliac artery.

21. The stent graft of claim 18 wherein the at least one socket has an expandable diameter.

22. The stent graft of claim 18 wherein the at least one socket is tapered.

23. The stent graft of claim 18 wherein the at least one socket further comprises reinforcing elements comprising nitinol or polyethylene fibers.

24. The stent graft of claim 18 wherein the at least one socket is attached to the stent graft by repolymerization or is thermoformed.

25. The stent graft of claim 18 wherein the at least one socket comprises radiopaque markers.

26. The stent graft of claim 18 wherein the at least one socket is comprised of polyurethane or ePTFE.

27. The stent graft of claim 18 comprising two sockets.

28. A stent graft for endoluminal implantation wherein the stent graft is adapted to telescopically receive a secondary stent graft extending into a renal artery, characterized in that the stent graft comprises at least one socket communicating with at least one opening in the stent graft, wherein at least one socket comprises a proximal end that flares around the at least one opening and an elastic wall forming a lumen with a stent at least partially encased within the wall.

29. The stent graft of claim 28 wherein the at least one socket comprises a proximal end and the proximal end flares around the at least one opening in the stent graft.

30. The stent graft of claim 28 wherein the at least one socket has an expandable diameter.

31. The stent graft of claim 28 wherein the at least one socket is tapered.

32. The stent graft of claim 28 wherein the at least one socket further comprises reinforcing elements comprising nitinol or polyethylene fibers.

33. The stent graft of claim 28 wherein the at least one socket extends radially from the stent graft at an acute, right, or obtuse angle.

34. The stent graft of claim 28 wherein the at least one socket is attached to the stent graft by repolymerization or is thermoformed.

35. The stent graft of claim 28 wherein the at least one socket comprises radiopaque markers.

36. The stent graft of claim 28 wherein the at least one socket is comprised of polyurethane or ePTFE.

37. The stent graft of claim 28 further comprising a secondary socket in communication with a second opening in the stent graft.

38. The stent graft of claim 28 further comprising a secondary socket for receiving a secondary stent graft comprising an elastic wall forming a lumen.

39. The stent graft of claim 28 wherein the stent graft further comprises a reinforcing ring around the opening and the stent is attached to the reinforcing ring while at least partially encased within the wall of the at least one socket.
