Abstract

A prosthetic device includes a main body, a first anchor, a second anchor, a first anchor spreader, and a second anchor spreader. The first anchor is coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body. The second anchor is coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body. The first anchor spreader is coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor. The second anchor spreader is coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

First claim

We claim:

1. A prosthetic device comprising:
a main body;
a valve inside the main body;
a first anchor coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body;
a second anchor coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body;
a first anchor spreader coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor; and
a second anchor spreader coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

2. The prosthetic device of claim 1 wherein the first anchor spreader pulls the first anchor away from the main body against the spring force of the first anchor and the second anchor spreader pulls the second anchor away from the main body against the spring force of the second anchor.

3. The prosthetic device of claim 1 wherein the spring force of the first anchor moves the first anchor back toward the main body when the force applied to the first anchor by the first spreader is removed and wherein the spring force of the second anchor moves the second anchor back toward the main body when the force applied to the second anchor by the second anchor spreader is removed.

4. The prosthetic device of claim 1 wherein the first anchor spreader is fastened directly to the first anchor and the second anchor spreader is fastened directly to the second anchor.

5. The prosthetic device of claim 1 wherein the first anchor is covered in cloth and the second anchor is covered in cloth.

6. The prosthetic device of claim 1 wherein the first anchor is configured to capture a first mitral valve leaflet between the main body and the first anchor and the second anchor is configured to capture a second mitral valve leaflet between the main body and the second anchor.

7. A prosthetic device for attachment to a mitral valve comprising:
a main body;
a valve inside the main body;
a pair of anchors coupled to the main body such that spring forces of the pair of anchors bias the pair of anchors toward the main body;
a pair of anchor spreaders coupled to the pair of anchors such that applying a force to the pair of anchor spreaders moves the pair of anchors away from the main body against the spring forces of the pair of anchors; and
wherein the pair of anchors are configured to capture first and second mitral valve leaflets between the main body and the pair of anchors.

8. The prosthetic device of claim 7 wherein the pair of anchor spreaders pull the pair of anchors away from the main body against the spring forces of the pair of anchors.

9. The prosthetic device of claim 7 wherein the spring forces of the pair of anchors moves the pair of anchors back toward the main body when the force applied to the pair of anchor spreaders is removed.

10. The prosthetic device of claim 7 wherein the pair of anchor spreaders are fastened directly to the pair of anchors.

11. The prosthetic device of claim 7 wherein the pair of anchors are covered in cloth.

12. A prosthetic device comprising:
a main body;
wherein the main body is a spacer;
a first anchor coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body;
a second anchor coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body;
a first anchor spreader coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor; and
a second anchor spreader coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

13. The prosthetic device of claim 12 wherein the first anchor spreader pulls the first anchor away from the main body against the spring force of the first anchor and the second anchor spreader pulls the second anchor away from the main body against the spring force of the second anchor.

14. The prosthetic device of claim 12 wherein the spring force of the first anchor moves the first anchor back toward the main body when the force applied to the first anchor by the first spreader is removed and wherein the spring force of the second anchor moves the second anchor back toward the main body when the force applied to the second anchor by the second anchor spreader is removed.

15. The prosthetic device of claim 12 wherein the first anchor spreader is fastened directly to the first anchor and the second anchor spreader is fastened directly to the second anchor.

16. The prosthetic device of claim 12 wherein the first anchor is covered in cloth and the second anchor is covered in cloth.

17. The prosthetic device of claim 12 wherein the first anchor is configured to capture a first mitral valve leaflet between the main body and the first anchor and the second anchor is configured to capture a second mitral valve leaflet between the main body and the second anchor.

18. A prosthetic device for attachment to a mitral valve comprising:
a main body;
wherein the main body is a spacer;
a pair of anchors coupled to the main body such that spring forces of the pair of anchors bias the pair of anchors toward the main body;
a pair of anchor spreaders coupled to the pair of anchors such that applying a force to the pair of anchor spreaders moves the pair of anchors away from the main body against the spring forces of the pair of anchors; and
wherein the pair of anchors are configured to capture first and second mitral valve leaflets between the main body and the pair of anchors.

19. The prosthetic device of claim 18 wherein the pair of anchor spreaders pull the pair of anchors away from the main body against the spring forces of the pair of anchors.

20. The prosthetic device of claim 18 wherein the spring forces of the pair of anchors moves the pair of anchors back toward the main body when the force applied to the pair of anchor spreaders is removed.

21. The prosthetic device of claim 18 wherein the pair of anchor spreaders are fastened directly to the pair of anchors.

22. The prosthetic device of claim 18 wherein the pair of anchors are covered in cloth.
