    Abstract: An implantable prosthetic valve includes a radially collapsible and radially expandable annular frame. The frame includes an annular main body sized to be implanted within a native mitral valve annulus. The frame also includes an atrial sealing member coupled to and extending radially away from the main body. The atrial sealing member is sized to extend over tissue of the native mitral annulus within a left atrium to reduce paravalvular leakage. The atrial sealing member includes an inner zig-zag portion and an outer zig-zag portion. The inner zig-zag portion and the outer zig-zag portion are connected to the main body portion only via a fabric to enhance flexibility of the atrial sealing member relative to the main body. The prosthetic valve also includes a valve member disposed within an interior of the frame.

    Abstract: A method of implanting a prosthetic apparatus preferably includes delivering the prosthetic apparatus to a native mitral valve and exposing ventricular anchors and a spacer body of the prosthetic apparatus from a distal end portion of a delivery apparatus. The ventricular anchors are controllably and forcibly expanded outwardly from the spacer body to an expanded configuration. The prosthetic apparatus is positioned relative to the native mitral valve such that native mitral valve leaflets are located between the ventricular anchors and the spacer body. The ventricular anchors are then contracted radially inwardly toward the spacer body to a compressed configuration. In the compressed configuration, the native mitral valve leaflets are secured between the ventricular anchors and the spacer body. After implantation, the spacer body is held between the native mitral valve leaflets, thereby blocking regurgitation and improving the function of the native mitral valve.
