  • Patent number: 10195026
    Abstract: Disclosed herein are prosthetic devices and related methods for implantation at the native mitral valve of the heart by drawing an atrial portion and a ventricular portion toward each other from opposite sides of the native mitral valve, clamping the native mitral valve therebetween. One or more retention members passing through the mitral valve orifice or through a puncture in the native valve anatomy can couple the atrial and ventricular members together and keep them anchored onto the native mitral valve anatomy. The atrial portion can seat against the atrial side of the mitral annulus while the ventricular portion can include hooks and/or a sub-annular ring that engage and capture the native mitral valve apparatus to provide anchorage. The described technology can avoid the need to use sutures to anchor a prosthetic device at the mitral valve region.
