    Abstract: A crimping device for a prosthetic heart valve can comprise an annular outer frame and an inner frame extending through the outer frame, the inner frame comprising first and second axial end portions and a plurality of jaw guides extending therebetween, where the inner frame defines a central opening extending therethrough. The crimping device can comprise a plurality of jaws operatively coupled to the inner and outer frames, each jaw having an inner portion positioned within the central opening of the inner frame and an engagement portion configured to slide along a respective jaw guide, each jaw guide comprising an inclined guiderail extending between the first and second axial end portions. Relative axial motion between the outer and inner frames causes radial motion of the jaws for crimping a prosthetic device positioned within the central opening.

    IPC: A61F2/24

    Abstract: A prosthetic device includes a main body, a first anchor, a second anchor, a first anchor spreader, and a second anchor spreader. The first anchor is coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body. The second anchor is coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body. The first anchor spreader is coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor. The second anchor spreader is coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

    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.

    IPC: A61F2/24

    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: This disclosure pertains generally to prosthetic devices and related methods for helping to seal native heart valves and prevent or reduce regurgitation therethrough, as well as devices and related methods for implanting such prosthetic devices. In some cases, a spacer having a single anchor can be implanted within a native heart valve. In some cases, a spacer having dual anchors can be implanted within a native heart valve. In some cases, devices can be used to extend the effective length of a native heart valve leaflet.

    Abstract: A crimping system for a prosthetic heart valve comprises a split funnel comprising an elongated annular body having an enlarged insertion end, a narrower outlet end, and a central opening extending along a central longitudinal axis of the split funnel, between the insertion end and the outlet end. The body comprises first and second slots extending axially along opposite sides of the body from the outlet end toward the insertion end, the first and second slots defining first and second split portions of the body extending circumferentially between the first and second slots on opposite sides of the central opening. The crimping device is configured to crimp a prosthetic heart valve moving axially through the central opening from the insertion end to the outlet end while allowing portions of the prosthetic heart valve to protrude through the first and second slots and remain in an expanded configuration.
