    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.

    IPC: A61F2/24

    Abstract: A method for heart valve replacement comprises forming an incision in a wall of a ventricle of a heart and inserting a delivery apparatus and a prosthetic heart valve through the incision and into the ventricle of the heart. The prosthetic valve comprises a self-expanding frame having an annular main body and a valve member disposed within the annular main body. The prosthetic valve further comprises an atrial sealing member formed by an annular metal ring and a fabric, wherein only the fabric of the atrial sealing member is connected to the main body for enhancing the flexibility and conformability of the atrial sealing member. The method further comprises deploying the prosthetic valve from the delivery apparatus such that the atrial sealing member extends radially outwardly from the main body within an atrium of the heart and the main body self-expands to a deployed state within a native heart valve.

    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.

    IPC: A61F2/24

    Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable coupling stent, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the coupling stent attached thereto. The coupling stent may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes a hollow two-piece handle through which a balloon catheter passes. A valve holder is stored with the heart valve and the handle easily attaches thereto to improve valve preparation steps.

    Abstract: A color-coded bioprosthetic valve system having a valve with an annular sewing ring, and a valve holder system with a holder sutured to the ring of the valve, a post operatively connected to the holder, and an adapter sutured to the post and having a color associated with the valve model and/or size. For example, the adapter may be blue to indicate that the valve of the system is a mitral valve of a particular type and/or size. The system may also include a flex handle that is configured to engage with the adapter. The handle has a color associated with the adapter such that a user is able to visually determine that the handle color matches the valve model. For example, the handle may have a grip that is colored blue to match the blue color of the adapter. Accordingly, the color-coded system enables users to confirm easily that the correct accessories such as the sizer or flex handle are being used with the correct valve.

    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.

    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.
