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.

- 9. A device comprising a catheter and a leaflet fastener applicator, said catheter having a proximal end, a distal end and suitable dimensions for insertion into a heart, said leaflet fastener applicator passing through said catheter such that an actuating element projects from said proximal end of said catheter while a fastening element projects from said distal end of said catheter, wherein said fastener applicator comprises a clip button including a first element with a plurality of spikes and a second element which clips onto said first element, said second element comprising openings to engage the spikes of said first element.
- 16. A fastener applicator comprising a first shaft, a first portion of a button clip having a plurality of sharp projections for piercing a heart valve leaflet a second shaft that slides over said first shaft, and a second portion of said button clip having a central hole said second portion of said button clip sliding over said first shaft by way of said central hole and not over said second shaft such that said second shaft can direct said second portion toward said first portion, wherein said second portion comprises openings to engage the projections of said first portion.
