Abstract

A method for performing a percutaneous valve bypass, the method comprising:

• • providing a bypass conduit having a first end and a second end;
  • connecting the first end of the bypass conduit to a first vascular structure at a first anastomosis;
  • connecting the second end of the bypass conduit to a second vascular structure at a second anastomosis;
  • advancing a percutaneous valve along the bypass conduit to a deployment site located within the bypass conduit; and
  • deploying the percutaneous valve at the deployment site so that fluid is permitted to pass from the second vascular structure to the first vascular structure but is prevented from passing from the first vascular structure to the second vascular structure.

Claims

1. A method for performing a percutaneous valve bypass, the method comprising:

providing a bypass conduit having a first end and a second end;

connecting the first end of the bypass conduit to a first vascular structure at a first anastomosis;

connecting the second end of the bypass conduit to a second vascular structure at a second anastomosis;

advancing a percutaneous valve along the bypass conduit to a deployment site located within the bypass conduit; and

deploying the percutaneous valve at the deployment site so that fluid is permitted to pass from the second vascular structure to the first vascular structure but is prevented from passing from the first vascular structure to the second vascular structure.

2. A method according to claim 1 wherein hemostasis is established at the first anastomosis after connecting the first end of the bypass conduit to the first vascular structure.

3. A method according to claim 2 wherein hemostasis is established at the second anastomosis after connecting the second end of the bypass conduit to the second vascular structure.

4. A method according to claim 3 wherein hemostasis is released at the first anastomosis after hemostasis has been established at the second anastomosis.

5. A method according to claim 4 wherein hemostasis is released at the second anastomosis after the percutaneous valve has been deployed at the deployment site.

6. A method according to claim 1 wherein the first vascular structure comprises the descending aorta and the second vascular structure comprises the left ventricle of the heart.

7. A method according to claim 6 wherein the bypass conduit comprises a descending aorta connector and a left ventricle connector, wherein the descending aorta connector comprises a first end and a second end and the left ventricle connector comprises a first end and a second end, and further wherein the first end of the descending aorta connector is configured to be connected to the descending aorta, the second end of the left ventricle connector is configured to be connected to the left ventricle, and the first end of the left ventricle connector is configured to be connected to the second end of the descending aorta connector.

8. A method according to claim 1 wherein the bypass conduit comprises a first portion formed out of a substantially radially non-compliant material and a second portion formed out of a substantially radially compliant material.

9. A method according to claim 8 wherein the bypass conduit comprises substantially radially compliant material at the deployment site.

10. A method according to claim 8 wherein the substantially radially non-compliant material comprises a woven material.

11. A method according to claim 10 wherein the woven material comprises at least one selected from the group consisting of woven polyester and woven polypropylene.

12. A method according to claim 8 wherein the substantially radially compliant material comprises a knitted material.

13. A method according to claim 12 wherein the knitted material comprises a knitted polyester.

14. A method according to claim 8 wherein the second portion is disposed longitudinally adjacent to the first portion.

15. A method according to claim 8 wherein the second portion is disposed coaxial with the first portion.

16. A method according to claim 15 wherein the second portion is disposed inboard of the first portion.

17. A method according to claim 1 wherein the percutaneous valve is advanced through the first vascular structure to gain entry into the bypass conduit.

18. A method according to claim 1 wherein the bypass conduit comprises a side branch communicating with the interior of the bypass conduit.

19. A method according to claim 18 wherein the percutaneous valve is advanced through the side branch to gain entry into the bypass conduit.

20. Apparatus for performing a percutaneous valve bypass, the apparatus comprising:

a bypass conduit comprising a first end for connection to a first vascular structure and a second end for connection to a second vascular structure; and

a percutaneous valve for disposition at a deployment site within the bypass conduit so that fluid is permitted to pass from the second vascular structure to the first vascular structure but is prevented from passing from the first vascular structure to the second vascular structure.

21. Apparatus according to claim 20 wherein the bypass conduit comprises a first connector and a second connector, wherein the first connector comprises a first end and a second end and the second connector comprises a first end and a second end, and further wherein the first end of the first connector is configured to be connected to the first vascular structure, the second end of the second connector is configured to be connected to the second vascular structure, and the first end of the second connector is configured to be connected to the second end of the first connector.

22. Apparatus according to claim 20 wherein the bypass conduit comprises a first portion formed out of a substantially radially non-compliant material and a second portion formed out of a substantially radially compliant material.

23. Apparatus according to claim 22 wherein the bypass conduit comprises substantially radially compliant material at the deployment site.

24. Apparatus according to claim 22 wherein the substantially radially non-compliant material comprises a woven material.

25. Apparatus according to claim 24 wherein the woven material comprises at least one selected from the group consisting of woven polyester and woven polypropylene.

26. Apparatus according to claim 22 wherein the substantially radially compliant material comprises a knitted material.

27. Apparatus according to claim 26 wherein the knitted material comprises a knitted polyester.

28. Apparatus according to claim 22 wherein the second portion is disposed longitudinally adjacent to the first portion.

29. Apparatus according to claim 22 wherein the second portion is disposed coaxial with the first portion.

30. Apparatus according to claim 29 wherein the second portion is disposed inboard of the first portion.

31. Apparatus according to claim 20 wherein the bypass conduit comprises a side branch communicating with the interior of the bypass conduit.

32. Apparatus according to claim 31 wherein the side branch is sized to permit the percutaneous valve to moved through the side branch and into the bypass conduit.
