Abstract
A prosthetic apparatus for implantation in a native heart valve includes a main body for placement within the native annulus. The main body is compressible to a radially compressed state for delivery into the heart and is self-expandable from the compressed state to a radially expanded state for implantation. A valve structure is mounted within a lumen of the main body and preferably forms three leaflets made of pericardium. Ventricular anchors are coupled to a ventricular end portion of the main body. The ventricular anchors are adapted to be straightened for delivery to the native heart valve and are biased to spring back to a pre-formed bent shape for capturing the native heart valve leaflets between the main body and the ventricular anchors. An atrial sealing member may be provided along an atrial portion of the main body for impeding the flow of blood between the main body and the native annulus.
