1. A system comprising:
a primary anchor comprising a proximal end and a distal end, wherein the distal end is configured to be driven into tissue, wherein the primary anchor comprises a helix,
a coaptation assistance device comprising a support structure comprising three or more supports extending through at least a portion of the coaptation assistance device, wherein the three or more supports are directly connected with a tubular extension, wherein the tubular extension extends upward from the three or more supports, wherein the primary anchor is configured to extend through the tubular extension so as to be configured to secure the coaptation assistance device to an annulus, wherein the coaptation assistance device comprises a superior edge configured to overlie the annulus, an inferior edge configured to extend toward the ventricle, and lateral edges extending between the superior edge and the inferior edge, wherein the coaptation assistance device comprises a first surface and a second surface, wherein the first surface and the second surface are bound by the superior edge, the inferior edge, the lateral edges, wherein the coaptation assistance device is configured to cross a plane of a heart valve, wherein the coaptation assistance device is configured to overlie a posterior leaflet, wherein the coaptation assistance device and an anterior leaflet are configured to provide closure or sealing of the valve,
at least one secondary anchor separate and spaced apart from the tubular extension and the primary anchor, wherein the one or more secondary anchors extend distally from the coaptation assistance device so as to be configured to engage the annulus.
