Abstract

Devices and methods for treating heart valves include members that assist the valve in closing during at least a portion of the cardiac cycle. Such devices include members configured to alter the shape of a valve annulus, reposition at least one papillary muscle, and/or plug an orifice of the valve so as to provide a coaptation surface for the valve leaflets.

Claims

1. A device for treating a heart valve, comprising:

an elongate member having a first end;

an anchoring mechanism secured to the first end of the elongate member, wherein the anchoring mechanism is configured to secure the elongate member to heart tissue; and

a plug member secured to the elongate member, wherein the plug member includes an external surface and is configured to be disposed within a heart valve so that leaflets of the heart valve contact the external surface during a portion of a cardiac cycle, wherein the plug member is expandable.

4. The device of claim 1, wherein the plug member comprises a collapsible hollow tube.

5. The device of claim 4, wherein the collapsible hollow tube comprises an open first end and an open second end.

6. The device of claim 1, wherein the plug member comprises a tapered structure having a relatively wide profile at a first end and tapering toward a second end, wherein the second end is opposing the first end.

7. The device of claim 1, wherein the plug member comprises at least 2 wing members with an articulation connecting the wing members.

8. The device of claim 1, wherein the plug member comprises a hollow cone.

9. The device of claim 1, wherein the elongate member has a second end, and the plug member is secured to the second end.

10. The device of claim 1, wherein the plug member is inflatable.

2. A device for treating a heart valve, comprising:

an elongate member having a first end;

an anchoring mechanism secured to the first end of the elongate member, wherein the anchoring mechanism is configured to secure the elongate member to heart tissue; and

a plug member secured to the elongate member, wherein the plug member includes an external surface and is configured to be disposed within a heart valve so that leaflets of the heart valve contact the external surface during a portion of a cardiac cycle,

wherein the device includes a first configuration for delivery within a sheath, and a second, expanded configuration when delivered from the sheath.

11. The device of claim 2, wherein the sheath comprises an open distal end, wherein the device is configured to be delivered within the sheath and to be deployed by advancing the device distally out of the open distal end.

12. The device of claim 11, wherein the plug member is expandable.

3. A device for treating a heart valve, comprising:

an elongate member having a first end, wherein the elongate member has a second end;

an anchoring mechanism secured to the first end of the elongate member, wherein the anchoring mechanism is configured to secure the elongate member to heart tissue; and

a plug member secured to the elongate member, wherein the plug member includes an external surface and is configured to be disposed within a heart valve so that leaflets of the heart valve contact the external surface during a portion of a cardiac cycle, and the plug member is secured to the second end.

13. The device of claim 3, wherein the plug member comprises a collapsible hollow tube.

14. The device of claim 3, wherein the plug member comprises a tapered structure having a relatively wide profile at a first end and tapering toward a second end, wherein the second end is opposing the first end.

15. The device of claim 3, wherein the plug member comprises at least 2 wing members with an articulation connecting the wing members.

16. The device of claim 3, wherein the plug member comprises a disk.

17. The device of claim 3, wherein the plug member comprises a piston-like structure.

18. The device of claim 3, wherein the plug member is substantially spherical.

19. The device of claim 3, wherein the plug member is substantially ellipsoidal.
