Abstract
Abstract A novel approach to mitral or tricuspid valve repair involves the performance of an edge-to-edge fastening/securing of opposing heart valve leaflets through a catheter entering the heart. Thus, a device is introduced including a leaflet fastener applicator through a cardiac catheter or other suitable catheter. The leaflet fastener applicator and cardiac catheter can be formed into a kit. A gripper can be used to hold the heart valve leaflets while they are fastened.

Claim 9
Dependent Claim
13 words
The device of claim 4 wherein said leaflet fastener comprises a crimp ring.
Claim 10
Dependent Claim
47 words
A heart valve gripper/fastener applicator comprising a leaflet gripper and a functionally independent leaflet fastener applicator wherein said gripper and said fastener applicator extend from a single shaft and are configured to by guided through a catheter, wherein said gripper is laterally juxtaposed with said fastener applicator.
Claim 11
Dependent Claim
47 words
A heart valve gripper/fastener applicator comprising a leaflet gripper and a functionally independent leaflet fastener applicator wherein said gripper and said fastener applicator extend from a single shaft and are configured to by guided through a catheter, wherein said gripper is laterally juxtaposed with said fastener applicator.
Claim 12
Dependent Claim
13 words

Claim 13
Dependent Claim
38 words
The gripper/fastener applicator of claim 9 wherein said fastener applicator comprises two opposing jaws, one of said jaws having a site for holding a tack and the second of said jaws having a site for holding a cap.
Claim 14
Dependent Claim
33 words
The gripper/fastener applicator of claim 9 wherein the gripper comprises a catheter lumen connecting holes near the distal end of said shaft to a suction device at the proximal end of said shaft.
Claim 15
Dependent Claim
13 words
