    Abstract: A delivery system for use with a prosthetic heart valve having a stent frame to which a valve structure is attached, includes a shaft assembly including a distal end and a coupling structure disposed near the distal end and configured to be coupled to a distal end of the prosthetic heart valve. The system includes a sheath assembly defining a lumen sized to slidably receive the shaft assembly. The delivery system is configured to transition from a loaded state in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve. The coupling structure is configured to provide a controlled expansion or contraction of the distal end of the prosthetic heart valve based on longitudinal movement of the distal end of the shaft assembly.

    Abstract: A valve prosthesis includes an expandable frame. The expandable frame has an outflow portion and an inflow portion connected to the outflow portion. The frame defines a central lumen extending between the outflow portion and the inflow portion. The frame is generally cylindrical in a fully expanded configuration. When the frame is in the fully expanded configuration, an outer surface of the inflow portion is concave. The inflow portion has an upper inflow portion and a lower inflow portion. When the frame is in the fully expanded configuration, the upper inflow portion flares outwardly from the central lumen of the frame to greater extent than the lower inflow portion.
