Abstract

Prosthetic valves for implantation in a body vessel are provided. Prosthetic valves according to the invention comprise first and second frame members and a graft member at least partially disposed between the first and second frame members. The graft member forms a valve that permits fluid flow through the body vessel in a first direction and substantially prevents fluid flow through the body vessel in a second, opposite direction.

Claims

1. A prosthetic valve for implantation in a body vessel, comprising:

a first frame member;

a second frame member disposed radially outward of the first frame member; and

a graft member forming a valve that permits fluid flow through said body vessel in a first direction and substantially prevents fluid flow through said body vessel in a second, opposite direction, at least a portion of the graft member disposed between the first and second frame members.

2. A prosthetic valve according to claim 1, wherein the graft member is attached to one of the first frame member and the second frame member.

3. A prosthetic valve according to claim 1, wherein the second frame member is disposed circumferentially around the first frame member.

4. A prosthetic valve according to claim 1, wherein the second frame member comprises a self-expandable member.

5. A prosthetic valve according to claim 1, wherein the second frame member expands upon application of an outwardly directed force.

6. A prosthetic valve according to claim 1, wherein the first frame member defines an extension point and wherein the graft member is attached to the first frame member at the extension point.

7. A prosthetic valve according to claim 6, wherein the extension point has a length, the first frame member has an inner diameter, and the length is between about 10% and about 1,000% of the inner diameter.

8. A prosthetic valve according to claim 1, wherein the first and second frame members have expanded and non-expanded configurations.

9. A prosthetic valve according to claim 1, wherein the graft member comprises a bioremodellable material.

10. A prosthetic valve according to claim 1, wherein the graft member comprises an extracellular matrix material.

11. A prosthetic valve according to claim 1, wherein the graft member comprises small intestine submucosa.

12. A prosthetic valve according to claim 1, wherein the valve comprises an evertable sleeve.

13. A prosthetic valve according to claim 1, wherein the graft member comprises a tubular member.

14. A prosthetic valve according to claim 1, wherein the first frame member has a first length, the second frame member has a second length, and the first length is substantially the same as the second length.

15. A prosthetic valve according to claim 1, wherein the first frame member has a first length, the second frame member has a second length, and the second length is greater than the first length.

16. A prosthetic valve according to claim 1, wherein the second frame member defines a sinus portion.

17. A prosthetic valve according to claim 16, wherein a portion of the valve is disposed within the sinus portion.

18. A prosthetic valve according to claim 1, wherein the second frame member has an external surface, a first portion of the graft member is disposed between the first and second frame members, and a second portion of the graft member is disposed on the external surface.

19. A prosthetic valve according to claim 18, wherein the graft member comprises a bioremodellable material.

20. A prosthetic valve according to claim 18, wherein the graft member comprises an extracellular matrix material.

21. A prosthetic valve according to claim 18, wherein the graft member comprises small intestine submucosa.

22. A medical device comprising a graft member at least partially disposed between first and second expandable frame members, the graft member forming a valve that permits fluid flow through a body vessel in a first direction and substantially prevents fluid flow through the body vessel in a second, opposite direction.

23. A prosthetic valve according to claim 22, wherein the graft member comprises a bioremodellable material.

24. A prosthetic valve according to claim 22, wherein the graft member comprises an extracellular matrix material.

25. A prosthetic valve according to claim 22, wherein the graft member comprises small intestine submucosa.

26. A medical device, comprising:

a first frame member;

a second frame member;

a graft member having first and second portions, the first portion disposed between the first and second frame members and the second portion forming a valve that permits fluid flow through a body vessel in a first direction and substantially prevents fluid flow through the body vessel in a second, opposite direction.

27. A prosthetic valve according to claim 26, wherein the graft member comprises a bioremodellable material.

28. A prosthetic valve according to claim 26, wherein the graft member comprises an extracellular matrix material.

29. A prosthetic valve according to claim 26, wherein the graft member comprises small intestine submucosa.
