Claims16
A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the coaptation assistance element comprising:
- a first surface and an opposed second surface;
- a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- and
- a superior zone and an inferior zone, the superior zone configured to reside in the plane of an annulus of the heart valve, the inferior zone extending downward from the superior zone,
- wherein the inferior zone comprises a leaflet configured to move relative to the inferior edge such that a distance between the leaflet and the inferior edge is configured to increase during systole and configured to decrease during diastole.
