The device can include contoured clasps which approximate the shape of the native valve when the clasps are in the closed position. The device can include a coaptation element with body portion including a plurality of struts and openings defining a lattice structure. One or more surfaces of one or more components of the device can be coated to improve the visibility of the device during deployment and implantation.

  • Patent number: 12115062
    Abstract: A prosthetic heart valve for implantation at a native heart valve includes a multi-part frame. The multi-part frame includes a cylindrical main body and a ventricular anchor component surrounding the main body. The main body includes a plurality of struts arranged in a lattice pattern. The ventricular anchor component is attached to the main body only at an outflow end of the main body and extends toward an inflow end of the main body. The prosthetic valve further includes a valve structure having three leaflets made from pericardium. 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 the native valve. The main body and the ventricular anchor component are formed separately and are attached by a locking mechanism for reducing strain between the main body and the ventricular anchor component.

  • Publication number: 20240315835
    Abstract: A self-expanding prosthetic heart valve includes an inner frame and an outer sealing frame. A lower region of the outer sealing frame is coupled to a lower region of the inner frame. At least a portion of the outer frame has a D-shape cross-section for conforming to a shape of a native heart valve annulus. Elongate anchors are positioned outwardly from the outer sealing frame for anchoring to native leaflets. Preferably, the native leaflets are secured between the anchors and an outer surface of the outer sealing frame. A valve body is positioned within an interior lumen of the inner frame and provides a one-way valve mechanism for replacing the function of the native leaflets. For additional stability, a further anchoring mechanism may extend from the inner frame for attachment to a heart wall. The prosthetic heart valve is well-suited for replacing the function of a native tricuspid valve.

  • Patent number: 12083010
    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.
