    Abstract: Apparatuses, systems, and methods for prosthetic valves. The prosthetic valves disclosed herein may be utilized for improved deployment, sealing, and anchoring to an implantation site. An implantation site may comprise a native heart valve or another implantation site in examples. Examples of prosthetic valves may include a proximal tensioning body positioned at a proximal portion of the prosthetic valve and a distal tensioning body positioned at a distal portion of the prosthetic valve. A sealing skirt may have a proximal end portion coupled to the proximal tensioning body and a distal end portion coupled to the distal tensioning body. The sealing skirt may be tensioned by the proximal tensioning body and the distal tensioning body and deflectable to conform to a shape of the native valve.

    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.

    Abstract: A replacement mitral valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native mitral valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors is coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.
