Abstract

A device, system and method affects mitral valve annulus geometry of a heart. The device includes a first anchor configured to be positioned within and fixed to the coronary sinus of the heart adjacent the mitral valve annulus within the heart. A cable is fixed to the first anchor and extends proximately therefrom and slidingly through a second anchor which is positioned and fixed in the heart proximal to the first anchor. A lock locks the cable to the second anchor when tension is applied to the cable for affecting the mitral valve annulus geometry.

Claims

1. A device for affecting mitral valve annulus geometry of a heart comprising:

a first anchor configured to be positioned within and fixed to the coronary sinus of the heart adjacent the mitral valve annulus within the heart;

a cable fixed to the first anchor and extending proximally from the first anchor within the heart;

a second anchor configured to be positioned in and fixed in the heart proximal to the first anchor and arranged to slidingly receive the cable; and

a lock that locks the cable on the second anchor, whereby when the first and second anchors are fixed within the heart, the cable is drawn proximally, and the cable is locked on the second anchor, the geometry of the mitral valve is affected.

2. The device of claim 1 wherein the second anchor is configured to be positioned and fixed in the coronary sinus.

3. The device of claim 1 wherein the second anchor is configured to be positioned and fixed in the right atrium.

4. The device of claim 1 wherein the cable includes a pressure distributor.

5. The device of claim 1 wherein the second anchor includes the lock.

6. The device of claim 5 wherein the lock includes a ratchet.

7. The device of claim 1 wherein the cable includes a coupling configured to releasably connect to a cable tension assembly.

8. A device for affecting mitral valve annulus geometry in a heart, the device comprising:

first anchor means for anchoring within the coronary sinus of the heart adjacent to the mitral valve annulus;

second anchor means for anchoring within the heart proximal to the first anchor means;

cable means fixed to the first anchor means and extending proximally from the first anchor means, the cable means being slidably received by the second anchor means for spanning between the first and second anchor means; and

lock means for locking the second anchor means to the cable means.

9. The device of claim 8 wherein the second anchor means is configured to be positioned within and anchored to the coronary sinus.

10. The device of claim 8 wherein the cable means includes pressure distributing means for distributing applied pressure.

11. The device of claim 8 wherein the lock means is carried by the second anchor means.

12. The device of claim 11 wherein the lock means includes a ratchet.

13. The device of claim 8 wherein the cable includes coupling means for coupling to a cable tension assembly.

14. A method of affecting mitral valve annulus geometry in a heart, the method including the steps of:

fixing a first anchor within the coronary sinus of the heart adjacent to the mitral valve annulus;

anchoring a second anchor within the heart proximal to the first anchor;

fixing a cable to the first anchor;

extending the cable proximally from the first anchor and slidably through the second anchor;

displacing the cable proximally relative to the second anchor to create tension in the cable; and

locking the second anchor to the cable.

15. The method of claim 14 wherein the anchoring step includes anchoring the second anchor in the coronary sinus.

16. The method of claim 14 wherein the displacing step includes releasably coupling the cable to a cable tension assembly.
