    Abstract: A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available to valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment. A catheter-based system and method for deployment is provided.

    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.

    IPC: A61B17/04

    Abstract: Suture clip deployment devices for applying suture clips to sutures are described. Some embodiments can include a generally tubular main body and a vacuum port located at the distal end, a hollow inner body longitudinally slidable within the main body and extending from the main body at its distal end, and a suture recess located in the generally tubular main body. At least one suture clip configured to frictionally fit on an outer surface of the inner body is deployed during use. Clip deployment can occur after a vacuum source is applied to the device so as to draw the suture into the device. The suture lines can be retrieved through the suture recess, and the device can be actuated so as to deliver the suture clip off the delivery device and onto the suture, locking the suture in place.
