Abstract: Apparatus for coupling a prosthetic chorda to an atrioventricular valve leaflet, the apparatus comprising: a neochorda delivery system comprising a steerable and pushable catheter housing a neochorda attached to a neochorda puncture needle, the catheter operable to push the puncture needle to puncture and thread the neochorda through a papillary muscle of a ventricle; a retriever system comprising a catheter housing a grabber operable to capture the neochorda puncture needle after being threaded through the papillary muscle and withdraw the neochorda puncture needle and neochorda from the ventricle; and a tissue clamping system comprising a catheter housing distal and proximal tissue clamps deployable to clamp a region of an atrioventricular valve between them and hold the region so that it may be punctured by the puncture needle to deliver the neochorda through the leaflet and to the papillary muscle.

Abstract: Apparatus for supporting a leaflet of a cardiac valve having an annulus and a plurality of leaflets extending from the annulus, the apparatus comprising: at least one support brace mountable to the cardiac valve and having: first and second ends each configured to be mounted to the cardiac valve in a region near a commissure of the cardiac valve associated with a leaflet of the plurality of leaflets; and a body configured to be attached to the leaflet and extend between the first and second ends along a lip of the leaflet.
