摘要:
A chordal replacement device comprising: a proximal anchor (3910), a distal anchor (3915) extending and affixed to a distal attachment site in a ventricle; and a flexible tether (3920) coupled to and tensioned between the proximal and distal anchors, wherein the proximal anchor may comprise a flexible crimp clip having one or more barbs that embed into and affix to a portion of a leaflet (LF) or a flexible patch and a leaflet attachment device, wherein the flexible patch is affixed to an upper surface of a portion of a flailing leaflet with the leaflet attachment device. The proximal anchor may also comprise a mesh stent deployable within an atrium, wherein the mesh stent is coupled to a flexible rod that extends through a valve commissure into the ventricle and wherein a distal end of a flexible rod couples to a distal anchor and provides consistent tension on the tether during a heart cycle.
