Abstract

A valve prosthesis and methods for implanting the prosthesis are provided. The prosthesis generally includes a self-expanding frame and two or more engagement arms. A valve prosthesis is sutured to the self-expanding frame. Each engagement arm corresponds to a native mitral valve leaflet. At least one engagement arm immobilizes the native leaflets, and holds the native leaflets close to the main frame. The prosthetic mitral valve frame also includes two or more anchor attachment points. Each anchor attachment point is attached to one or more anchors that help attach the valve prosthesis to the heart.

First claim

What is claimed is:

1. A heart valve device comprising:
a frame configured to expand within and support against a native valve annulus;
a prosthetic valve coupled to the frame; and
an anchor, wherein a first end of the anchor is coupled to the frame and a second end of the anchor is operatively coupled to an anchoring element that is configured to attach to a heart structure, the anchoring element including a lock having a first position that permits adjustment of tension in the anchor and a second position that locks the anchor at a desired tension, wherein the anchoring element is a clip and wherein the lock of the anchoring element is comprised of opposing jaw portions of the clip.

2. The device of claim 1 , wherein the anchoring element is configured to attach to the wall of the left ventricle.

3. The device of claim 1 , wherein the anchoring element is configured to attach to a papillary muscle of the heart.

4. The device of claim 1 , wherein the anchor is configured to function as an artificial chordae.

5. The device of claim 1 , wherein the prosthetic valve is sutured to the frame.

6. The device of claim 1 , wherein the frame comprises an anchor attachment point.

7. The device of claim 1 , wherein the opposing jaw portions are separated in the first position of the lock that permits adjustment of tension in the anchor.

8. The device of claim 1 , wherein the opposing jaw portions are closed together in the second position of the lock that locks the anchor at a desired tension.

9. The device of claim 1 , wherein the device is configured to be delivered transseptally into the left ventricle of the heart.

10. The device of claim 1 , wherein the device is configured to be delivered transapically into the left ventricle of the heart.

11. The device of claim 1 , w herein the device is configured to be delivered transfemorally into the left ventricle of the heart.

12. The device of claim 1 , wherein the anchor comprises a tether.
