Mitral and tricuspid valve repair
First Claim
1. A heart valve leaflet fastener comprising at least one pair of arms, at least one arm of the pair of arms having a tapered protrusion extending toward the other arm of the pair of arms and the other arm of the at least one pair of arms having a tapered slot for accepting the tapered protrusion therein for fastening two adjacent tissue heart valve leaflets, wherein the arms pivot from one orientation to a gripping position with ends of respective paired arms being directed toward each other such that the tapered protrusion positions within the tapered slot to grip the two adjacent tissue heart valve leaflets.

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.

- 1. A heart valve leaflet fastener comprising at least one pair of arms, at least one arm of the pair of arms having a tapered protrusion extending toward the other arm of the pair of arms and the other arm of the at least one pair of arms having a tapered slot for accepting the tapered protrusion therein for fastening two adjacent tissue heart valve leaflets, wherein the arms pivot from one orientation to a gripping position with ends of respective paired arms being directed toward each other such that the tapered protrusion positions within the tapered slot to grip the two adjacent tissue heart valve leaflets.
- 9. A heart valve repair instrument comprising a shaft, a cap, a gripper and a flexible rod, wherein the gripper comprises a plurality of arms radiating from a pivot with each arm having a spike, wherein the cap is located distal to the pivot and the pivot is located distal to the shaft, and wherein the flexible rod connects to the cap to provide for movement of the cap relative to the pivot of the gripper and the shaft by pulling the flexible rod, the cap having an opening that can be positioned over the pivot to lock the arms in a closed position.
- 20. A fastening member comprising a cap and a gripper configured to grip a tissue heart valve leaflet, the cap being slideable relative to the gripper, wherein the gripper comprises a plurality of arms radiating from a pivot, with at least a first arm having a tapered spike, and at least a second arm having a plurality of spikes such that a tapered slot is formed between the plurality of spikes, wherein the pivot is inserted within an opening in the cap to lock the arms in a collapsed gripping position such that the tapered spike positions within the tapered slot.
