1. A coaptation implant comprising:
- a coaptation surface configured for an anterior leaflet of a valve to coapt against;
a superior edge, lateral edges, and an inferior edge, wherein the superior edge has a length greater than a length of the inferior edge, such that a transverse distance between the lateral edges generally decreases from the superior edge to the inferior edge of the coaptation implant;
a hub located near the superior edge;
a helical anchor configured to be rotated relative to the hub to engage tissue;
at least one strut, wherein a strut of the at least one strut extends from the hub toward the inferior edge, the at least one strut arranged to assist in maintaining the shape of the coaptation implant upon placement, while allowing the coaptation implant to assume a reduced configuration for deployment through a catheter.

10. A coaptation implant comprising:
-
a coaptation surface configured for an anterior leaflet of a valve to coapt against; a superior edge, lateral edges, and an inferior edge, wherein the superior edge has a length greater than a length of the inferior edge, such that a transverse distance between the lateral edges generally decreases from the superior edge to the inferior edge of the coaptation implant; a hub located near the superior edge; a helical anchor configured to be rotated relative to the hub to engage tissue; a strut extending from the hub toward the inferior edge; and one or more additional struts, wherein the one or more additional struts curve laterally toward the superior edge to assist in maintaining the shape of a proximal portion of the coaptation implant upon deployment. - View Dependent Claims (11, 12, 13, 14)
