1. A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the coaptation assistance element comprising:
- a first coaptation 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 comprising the first coaptation surface and the opposed second surface,wherein the inferior zone comprises a laminate layer such that a thickness of the inferior zone is greater than a thickness of a portion of the superior zone.

11. A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the heart valve comprising native leaflets and an annulus, the coaptation assistance element comprising:
-
a body comprising a first surface and an opposed second surface, each surface bounded by a first lateral edge, a second lateral edge, an inferior edge, and a superior edge; a hub spaced inward from each of the first lateral edge, the second lateral edge, the inferior edge, and the superior edge, the hub configured to reside near the annulus; and a coaptation zone configured to provide a surface for at least one of the native leaflets to coapt against, wherein the coaptation zone comprises a laminate layer such that a thickness of the coaptation zone is greater than a thickness of an unlaminated portion of the body superior to the coaptation zone. - View Dependent Claims (12, 13, 14, 15, 16)

17. A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the heart valve comprising a posterior leaflet and an annulus, the coaptation assistance element comprising:
-
a body comprising a first surface and an opposed second surface, each surface bounded by a first lateral edge, a second lateral edge, an inferior edge, and a superior edge; an annular zone and a ventricular zone, the annular zone configured to be located near the annulus of the heart valve, the ventricular zone extending from the annular zone and configured to be located near the posterior leaflet, wherein the ventricular zone comprises at least one reinforcement layer such that a thickness of the ventricular zone is greater than a thickness of a portion of the annular zone. - View Dependent Claims (18, 19, 20)
