Abstract

A method for reducing mitral regurgitation comprising: providing a plication assembly comprising a first anchoring element, a second anchoring element, and a linkage construct connecting the first anchoring element to the second anchoring element; positioning the first anchoring element in the coronary sinus adjacent to the mitral annulus, and positioning the second anchoring element in another area of the mitral annulus so that the linkage construct extends across the opening of the mitral valve and holds the mitral valve in a reconfigured configuration so as to reduce mitral regurgitation. An apparatus for reducing mitral regurgitation comprising: a plication assembly comprising a first anchoring element, a second anchoring element, and a linkage construct connecting the first anchoring element to the second anchoring element; and a catheter adapted to deliver the first anchoring element to the coronary sinus.

Claims

1. A method for reducing mitral regurgitation comprising:

providing a plication assembly comprising a first anchoring element, a second anchoring element, and a linkage construct connecting the first anchoring element to the second anchoring element;

positioning the first anchoring element in the coronary sinus adjacent to the mitral annulus, and positioning the second anchoring element in another area of the mitral annulus so that the linkage construct extends across the opening of the mitral valve and holds the mitral valve in a reconfigured configuration so as to reduce mitral regurgitation.

2. A method according to claim 1 wherein the second anchoring element is positioned in the mitral annulus adjacent to the aortic valve.

3. A method according to claim 1 wherein the first anchoring element is positioned within the coronary sinus using a catheter.

4. A method according to claim 1 wherein the first anchoring element is positioned within the coronary sinus endoluminally.

5. A method according to claim 1 wherein the second anchoring element is positioned within the mitral annulus using a catheter.

6. A method according to claim 1 wherein the second anchoring element is positioned within the mitral annulus endoluminally.

7. A method according to claim 1 wherein the first anchoring element and the second anchoring element are delivered using the same delivery catheter.

8. A method according to claim 7 where the delivery catheter is maneuvered into position with the assistance of a second catheter.

9. A method according claim 8 wherein the second catheter is positioned in the left atrium.

10. A method according to claim 8 wherein the second catheter is positioned in the left atrium via the aorta.

11. A method according to claim 8 wherein the second catheter is positioned in the left atrium transseptally.

12. A method according to claim 1 wherein the first anchoring element is supported by scaffolding.

13. A method according to claim 1 wherein one of the first anchoring element and the second anchoring element is deployed, the mitral valve is placed into its reconfigured configuration, and then the second of the first anchoring element and the second anchoring element is deployed.

14. A method according to claim 1 wherein the first anchoring element is deployed, the second anchoring element is deployed, the mitral valve is placed into its reconfigured configuration, and then the linkage construct is configured.

15. A method according to claim 1:

wherein the plication assembly comprises a plurality of first anchoring elements, at least one second anchoring element, and a plurality of linkage constructs connecting the plurality of first anchoring elements to the at least one second anchoring element; and

further wherein the plurality of first anchoring elements are positioned in the coronary sinus adjacent to the mitral annulus, and the at least one second anchoring element is positioned in another area of the mitral annulus so that the plurality of linkage constructs extend across the opening of the mitral valve and hold the mitral valve in a reconfigured configuration so as to reduce mitral regurgitation.

16. A method according to claim 15 wherein the plurality of first anchoring elements are supported by scaffolding.

17. A method according to claim 16 wherein the scaffolding comprises a single scaffolding unit.

18. A method according to claim 16 wherein the scaffolding comprises a plurality of scaffolding units.

19. A method according to claim 1:

wherein the plication assembly comprises at least one first anchoring element, a plurality of second anchoring elements, and a plurality of linkage constructs connecting the at least one first anchoring element to the plurality of second anchoring elements; and

further wherein the at least one first anchoring element is positioned in the coronary sinus adjacent to the mitral annulus, and the plurality of second anchoring elements are positioned in other areas of the mitral annulus so that the plurality of linkage constructs extend across the opening of the mitral valve and hold the mitral valve in a reconfigured configuration so as to reduce mitral regurgitation.

21. A method according claim 8 wherein the second catheter is positioned in the left ventricle.

22. A method according to claim 8 wherein the second catheter is positioned in the left ventricle via the aorta.

23. A method according to claim 8 wherein the second catheter is positioned in the left ventricle transseptally.

20. An apparatus for reducing mitral regurgitation comprising:

a plication assembly comprising a first anchoring element, a second anchoring element, and a linkage construct connecting the first anchoring element to the second anchoring element; and

a catheter adapted to deliver the first anchoring element to the coronary sinus.
