Abstract

Valve repair apparatus and methods for ensuring proper coaptation and operation of the leaflets of a heart valve. Main aspects of the disclosure relate to devices including a support member configured for attachment to the heart valve annulus, a post extending from the support member away from the plane of the annulus and a connector coupled with the post and configured for attachment to at least one of the leaflets. The various embodiments may include a replacement heart valve connected with the support member for facilitating full replacement as opposed to near repair of an existing native heart valve. Various other devices include support structure and one or more posts connected to opposite sides of the support structure and extending from one side of the valve annulus to another to modify the shape of the annulus.

Claims

1. A device for supporting a mitral valve in a patient, the mitral valve including an annulus generally lying in a plane and anterior and posterior leaflets connected therewith and adapted to open and close to selectively allow and prevent blood flow, the device comprising:

support structure configured for attachment to the annulus, said support structure having opposite portions positionable on opposite anterior and posterior sides of the annulus, and

a post extending from said support structure and configured to extend away from the plane of the annulus and onto the posterior side adjacent a posterior leaflet edge, and

a connector coupled with said post and configured for attachment to the posterior leaflet edge.

2. The device of claim 1, wherein said connector further comprises at least one flexible tensile member coupled with said post for supporting said posterior leaflet during operation of the valve.

3. The device of claim 1, wherein said connector is configured to connect said post directly adjacent an edge of at least one of said leaflets.

21. The device of claim 1, wherein said post comprises a leaflet supporting member coupled between the opposite portions of said support structure.

22. The device of claim 21, wherein said post comprises a wire.

23. The device of claim 21, wherein said connector is configured to couple said leaflet supporting member directly to one of said leaflets.

4. A device for supporting a heart valve in a patient, the heart valve including an annulus and a plurality of leaflets connected therewith and adapted to open and close to selectively allow and prevent blood flow, the device comprising:

a support structure configured for attachment to the heart valve annulus, and

a post connected to opposite sides of said support structure and configured to extend from one side of the annulus to another side of the annulus.

5. The device of claim 4, wherein said post is length adjustable to allow variable modification of the shape of said annulus.

6. The device of claim 4 further comprising at least one additional post connected to opposite sides of said support structure and configured to extend from one side of the annulus to another side of the annulus.

7. The device of claim 4, wherein said support structure further comprises discrete support segments connected by said post.

8. The device of claim 4, wherein said post extends substantially in the same plane as the support structure.

9. The device of claim 4, wherein said post extends substantially out of a plane containing said support structure.

10. A device for supporting a heart valve in a patient, the heart valve including an annulus and a plurality of leaflets connected therewith and adapted to open and close to selectively allow and prevent blood flow, the device comprising:

support structure configured for attachment on opposite sides of the heart valve annulus, and

a post connected to the support structure and configured to extend from one side of the annulus to another side of the annulus, whereby said support structure fixes the shape of said annulus.

11. The device of claim 10, wherein said post is adjustable in length to allow adjustment in the shape of said annulus.

12. The device of claim 10, further comprising a second post connected to the support structure and configured to extend from one side of the annulus to another side of the annulus.

13. The device of claim 10, wherein each of said posts is adjustable in length to allow adjustment in the shape of said annulus.

14. A method of supporting a heart valve, the heart valve having an annulus generally lying in a plane and a plurality of leaflets connected therewith and adapted to open and close to selectively allow and prevent blood flow, the method comprising:

connecting a support structure to said annulus,

providing a post extending from said support structure, and

connecting the post to one of said valve leaflets to support the leaflet during opening and closing thereof.

15. The method of claim 14, wherein the step of connecting the post to one of the valve leaflets further comprises connecting a flexible tensile member between the post and the leaflet.

16. The method of claim 15, wherein the step of connecting the flexible tensile member between the post and the leaflet further comprises connecting a suture between the post and the leaflet.

17. The method of claim 15, wherein the step of connecting the flexible tensile member between the post and the leaflet further comprises connecting a native chord between the post and the leaflet.

18. The method of claim 14 further comprising:

connecting said post to another leaflet of said heart valve.

19. The method of claim 14 further comprising directly connecting said post to central portions of two adjacent leaflets to affix the central portions of said leaflets together.

20. The method of claim 14, wherein providing the post further comprises:

extending the post out of the plane of the annulus and between the leaflets.
