Abstract

The invention relates to a system for repairing a heart valve comprising a catheter, said catheter comprising an engagement member, the engagement member having at its distal end a hook capable of engaging with the surface of a prolapsed heart valve leaflet; and a fastener capable of deploying a fastening means to said leaflet.

Claims

1. A system for repairing a heart valve comprising a catheter, said catheter comprising an engagement member, the engagement member having at its distal end a hook capable of engaging with the surface of a prolapsed heart valve leaflet;

and a fastener capable of deploying a fastening means to said leaflet.

2. A system according to claim 1 wherein the system has a single engagement member.

3. A system according to claim 1 wherein the engagement member is capable of inverting said leaflet.

4. A system according to claim 1 wherein the engagement member is capable of aligning said leaflet with the second leaflet in normal coaptation.

5. A system according to claim 1 wherein the heart valve is the mitral heart valve or tricuspid heart valve.

6. A system according to claim 1 wherein the leaflet is the posterior leaflet.

7. A system according to claim 1 wherein the leaflet is the anterior leaflet.

8. A system according to claim 1 wherein the engagement member engages with the prolapsed segment of the leaflet.

9. A system according to claim 1 wherein the fastening means is made of a biocompatible material.

10. A system according to claim 1 wherein the fastening means is made of a shape memory material.

11. A system according to claim 1 wherein the fastening means is a clip.

12. The use of a system according to claim 1 in the treatment of mitral regurgitation.

13. A method for repairing a heart valve comprising engaging the prolapsed portion of a single leaflet of a heart valve with an engagement member;

inverting said prolapsed portion;

deploying a fastening means to said inverted prolapsed portion and releasing the engagement member.

14. A method according to claim 13 wherein the distal end of the engagement member comprises a hook capable of engaging with the surface of a heart valve leaflet.

15. A method according to claim 13 wherein the engagement member engages with the prolapsed segment of the leaflet.

16. A method according to claim 13 wherein the fastening means is made of a biocompatible material.

17. A method according to claim 13 wherein the fastening means is made of a shape memory material.

18. A method according to claim 13 wherein the fastening means is a clip.

19. A method according to claim 13 wherein the engagement member and fastener are housed in a single catheter.

20. A method according to claim 13 wherein the engagement member and fastener are housed in separate catheters.

21. A method according to claim 13 wherein the catheter is inserted through the femoral artery.

22. A method according to claim 13 using a system for repairing a heart valve comprising a catheter, said catheter comprising an engagement members the engagement member having at its distal end a hook capable of engaging with the surface of a prolapsed heart valve leaflet;

and a fastener capable of deploying a fastening means to said leaflet.
