1. A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the coaptation assistance element comprising:
an annular section configured to reside in the plane of an annulus of the heart valve;
a leaflet section configured to extend from the annular section;
wherein the leaflet section comprises a leaflet frame;
wherein the leaflet section comprises a leaflet-apposing valve body element, wherein the leaflet-apposing valve body element is molded into a pre-set curved configuration to be partially convex relative to the leaflet frame and the leaflet-apposing vale body element is molded into the pre-set curved configuration to be partially concave relative to the leaflet frame,
wherein the partially convex portion of the pre-set curved configuration of the leaflet-apposing valve body element is inside the frame at the same time that the partially concave portion of the pre-set curved configuration of the leaflet-apposing valve body element is outside of the frame,
wherein the partially convex portion of the pre-set curved configuration of the leaflet-apposing valve body element is biased to be configured to engage with a portion of an anterior leaflet at the same time that the partially concave portion of the pre-set curved configuration of the leaflet-apposing valve body element is biased to be configured to engage with a portion of a posterior leaflet.
