Abstract
An apparatus for augmenting the length of native chordae tendineae to restore physiological leaflet coaptation. The apparatus includes a delivery device having a lumen therein which at least partially houses a prosthetic cord. The prosthetic cord has a first end with a first clasp configured to attach to a native chordae tendineae and a second end with a second clasp configured to attach to the native chordae tendineae. The native chordae tendineae is severed between the first clasp and the second clasp, and the length of the prosthetic cord between the first clasp and the second clasp is adjusted until physiological leaflet coaptation is restored.
