    Abstract: A mitral valve prosthesis includes an hourglass shaped inner frame and a bulbous outer frame. A valve body having a plurality of leaflets is positioned within an interior region of the inner frame. The leaflets are shaped to substantially conform to an interior surface of the inner frame when the leaflets are in an open position. As a result, the gap between the leaflets and the inner frame is decreased, thereby reducing the likelihood of thrombus formation. Ventricular anchors are preferably provided along a distal end of the inner frame. The anchors extend proximally for placement behind native mitral valve leaflets. A fabric skirt may extend along an inner or outer surface of the outer frame. In preferred embodiments, the fabric skirt extends distally beyond a distal end of the outer frame and is adapted for forming a seal along the mitral valve annulus.

    Abstract: A prosthetic heart valve for deployment in a native heart valve. The prosthetic heart valve includes an inner frame and a plurality of anchors extending from a distal portion of the inner frame. An outer sealing frame is positioned radially outward of the inner frame. The distal end portion of the outer frame is attached to a distal portion of the inner frame by a flexible cloth material such that the outer frame can move axially or tilt with respect to the inner frame. The anchors are shaped to capture native leaflets between the anchors and the outer frame to secure the prosthetic valve in the native heart valve. Prosthetic valve leaflets are provided in a lumen of the inner frame for allowing one way flow through the prosthetic valve, thereby replacing the function of the native heart valve.

    Abstract: Embodiments of a crimping device for crimping a radially expandable and compressible prosthetic valve are disclosed. A crimping device can comprise a housing configured to receive a prosthetic valve in a radially expanded state. The housing member can include a funnel segment and an outlet in communication with the funnel segment. The crimping device can further comprise an actuator rotatably coupled to the housing, wherein rotation of the actuator relative to the housing causes the prosthetic valve to move axially through the funnel segment such that at least a portion of the prosthetic valve compresses radially by engagement with the funnel segment and exits the crimping device via the outlet.
