Abstract

Devices and methods for supplementing and/or replacing native cardiac valve functionality, e.g., the mitral valve with a single prosthetic leaflet. An exemplary device is directed to dysfunctional mitral valves. In some cases, the entire device, including the single prosthetic leaflet, will be arranged entirely above the dysfunctional mitral valves and, therefore, disposed entirely within the left atrium. In other cases, the valve support and/or single prosthetic leaflet may extend a distance into the annulus between the left atrium and left ventricle. In some cases, the device will not physically interact with the native leaflets. In other cases, the device may physically interact with the native leaflets.
