    Abstract: Embodiments of the present invention provide prosthetic valves having sealing members on the external surface thereof. The prosthetic heart valves of the present invention are preferably delivered by catheter directly through the apex of the heart or by other close range transcatheter delivery methods. Because these methods of implantation require a shorter length of catheter, a prosthetic valve can be more accurately oriented in the desired implantation location. Fluoroscopy can be used to further assist in orientation of the valve. The sealing members of the present invention can be positioned on the prosthetic valve such that, when the prosthetic valve is implanted in a native annulus, each provided sealing member is located adjacent to a commissural point of the native valve leaflets. Because the sealing members are precisely oriented on the prosthetic valve, a physician can ensure that the sealing members are aligned with the commissural points of the native valve leaflets. In embodiments of the present invention, the prosthetic valve can have a waisted middle section, and the sealing members can be located in the waisted middle section such that the crimped diameter of the prosthetic valve is not negatively impacted by the sealing, members.

    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, an intermediate portion, and a first coupling structure disposed near the distal end and configured to be coupled to a distal end of the prosthetic heart valve via a first tether. A sheath assembly defines 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in which the sheath assembly encompasses the prosthetic heart valve to a deployed state in which the sheath assembly is withdrawn from the prosthetic heart valve.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 first coupling structure is configured to be manipulated in a first direction to provide a controlled expansion or contraction of the distal end of the prosthetic heart valve.
