Abstract

An artificial chordae system can comprise a surgical pad configured to be externally positioned over an opening formed in a portion of a heart wall adjacent to a heart ventricle, and a tether comprising a cord and a tissue ingrowth promoting coating over at least a portion of the cord, the tether comprising a distal portion being configured to couple a heart valve leaflet and a proximal portion being coupled to the surgical pad. The tether can be dimensioned to extend from the heart valve leaflet through the heart ventricle to the opening in the heart wall, and through the opening in the heart wall to the surgical pad. The tissue ingrowth promoting coating can comprise a protein and be configured to promote native tissue growth over the cord to provide regenerated native tissue over the tether for coupling the heart valve leaflet to the heart wall.
