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.
