Abstract

Apparatus and methods for repairing a cardiac valve, e.g., a mitral valve, are provided. The apparatus may include an expandable frame defining a curved structure in the expanded deployed state and a membrane coupled to the expandable frame. The membrane may curve around a native leaflet, e.g., the posterior leaflet, in a first plane and curve around another leaflet, e.g., the anterior leaflet, in an orthogonal plane. The membrane may be adapted to be suspended in the flow path of the cardiac valve such a first surface of the membrane abuts the native leaflet during systole and a second surface of the membrane abuts the other native leaflet during systole, thereby reducing cardiac valve regurgitation.
