Abstract: Coaptation-assist devices (20) are provided for treating a native atrioventricular valve. The coaptation-assist devices (20) include a ventricular anchor (30), which includes one or more wires (35), and which is configured to be positioned in a ventricle; and a neo-leaflet (32), which is supported by the ventricular anchor (30) and is configured to at least partially replace function of a target native leaflet of the native atrioventricular valve by providing a surface of coaptation (34) for one or more opposing native leaflets. In some configurations, the ventricular anchor (30) includes a proximal subannular anchor (54), which includes a digitate anchor (56) that is shaped so as to define a plurality of fingers (60) having a plurality of curved superior peaks (66) that point in a superior direction and engage a subannular surface of the target native leaflet. Other embodiments are also described.

Abstract: A coaptation-assist device (20, 120A, 120B, 120C, 320A, 320B, 420, 720) is provided for treating a native atrioventricular valve, including a loop-shaped ventricular anchor (30, 130, 330, 430, 730) which includes an anchor-loop wire loop (50, 150, 350, 450, 750), which defines at least a portion of a border of the loop-shaped ventricular anchor, and is configured to be positioned in a ventricle, extending between a ventricular apical area and a subannular surface of a target native leaflet, and to remain anchored in position against surrounding anatomy, including the subannular surface, a ventricular wall, and the ventricular apical area. A neo-leaflet (32, 132A, 132B, 132C, 332A, 332B, 332A, 332B, 432, 732) is supported by the loop-shaped ventricular anchor and is configured to at least partially replace function of the target native leaflet by providing a surface of coaptation (34, 434, 734) for one or more opposing native leaflets that oppose the target native leaflet. Other embodiments are also described.
