    Abstract: A prosthetic mitral valve can include an outer frame, an inner frame, a valve structure, and a sealing member. The outer frame comprises a plurality of first struts arranged in a lattice pattern and defining a first lumen. The outer frame is self-expandable from a compressed state to an expanded state. The inner frame comprises a plurality of second struts arranged in a lattice pattern and defining a second lumen. The inner frame is disposed within the first lumen of the outer frame, is self-expandable from a compressed state to an expanded state. The valve structure comprises three leaflets made from pericardium and is mounted within the second lumen of the inner frame. The sealing member is coupled to and extends radially outwardly from an atrial end of the outer frame and is configured to engage native tissue of the heart on an atrial side of the native mitral valve.

    IPC: A61F2/24

    Abstract: A prosthetic apparatus for implantation in a native mitral valve includes a main body for placement within the native mitral 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. An atrial sealing member is disposed along an atrial portion of the main body and ventricular anchors are coupled to a ventricular portion of the main body. The atrial sealing member impedes the flow of blood between the main body and the native annulus. The ventricular anchors are positioned outside the main body for capturing native mitral valve leaflets between the main body and the ventricular anchors.

    Abstract: A prosthetic apparatus configured for implantation in the native mitral valve region of the heart includes a main body that is self-expandable from a compressed state to a radially expanded state. The prosthetic apparatus comprises at least one ventricular anchor coupled to the main body and disposed outside of the main body for capturing a native valve leaflet between the anchor and an outer surface of the main body. In one preferred method of implantation, the prosthetic apparatus is rotated within the native mitral valve region such that a portion of the anchor moves horizontally behind adjacent chordae for anchoring the prosthetic apparatus in the native mitral valve.

    IPC: A61F2/24

    Abstract: A prosthetic heart valve including a multi-part frame having an annular main body formed from a plurality of struts, an atrial anchor that extends radially outward from an inflow end portion of the main body, one or more ventricular anchors that are configured to be positioned behind a native valve leaflet, and a valve structure disposed in a lumen of the main body. Each of the ventricular anchors includes first and second end portions coupled to the outflow end portion of the main body and an intermediate portion forming a bend that forms a free end portion of the ventricular anchor that extends toward an inflow end portion of the main body. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of a native valve.

    Abstract: A prosthetic heart valve includes a multi-part frame having a first annular body and an anchor component that includes a second annular body circumscribing the first annular body. The first annular body includes a plurality of struts arranged in a lattice pattern and defining a lumen. The anchor component further includes one or more ventricular anchors extending from the second annular body toward an inflow end portion of the first annular body. A fabric layer is disposed on an inner surface of the first annular body and sutured to the struts. A valve structure including three leaflets is disposed within the lumen and inlet ends of the leaflets are sutured to the fabric layer. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of a native valve.
