Abstract: An apparatus for partially supporting a leaflet of a regurgitant heart valve includes at least one subvalvular device including a subvalvular supporting portion and an anchor portion. The subvalvular supporting portion and anchor portion are each at least partially formed from at least one of braided mesh strands of a first configuration, braided mesh strands of a second configuration, a balloon, a plurality of longitudinally extending struts, and a plurality of laterally extending struts. A connector neck is interposed longitudinally between, and is attached to both of, the subvalvular supporting portion and the anchor portion. The connector neck penetrates longitudinally through at least one of a base of the leaflet and an annulus of the heart valve at a manufactured puncture site.

Abstract: An apparatus for at least partially repairing a regurgitant heart valve includes at least one subvalvular device defining a longitudinal axis and including a subvalvular portion located adjacent a subvalvular cardiac wall adjacent to the heart valve. An anchor portion is adjacent to, and is longitudinally spaced from, the subvalvular portion. A connector neck is interposed longitudinally between, and is attached to both of, the subvalvular portion and the anchor portion. The connector neck penetrates longitudinally through at least one of a base of the first valve leaflet and an annulus of the heart valve at a manufactured puncture site. A fastener is selectively connected to the at least one subvalvular device. The fastener penetrates through at least one of the first and second valve leaflets to maintain the at least one leaflet in a predetermined position with respect to the at least one subvalvular device.
