Abstract
An assembly for treating a native valve in a human heart includes a prosthetic heart valve having an expandable frame and a valvular structure. The assembly also includes a tubular sleeve and a valve catheter disposed within the sleeve. A plurality of metal extension arms are coupled to the valve catheter for holding the prosthetic heart valve. The extension arms are configured to radially expand with the prosthetic heart valve during expansion of the prosthetic heart valve at a treatment site. A plurality of metal rods extend distally from the valve catheter. The rods are axially movable relative to the extension arms. A plurality of release members are provided for releasing the prosthetic heart valve from the extension arms upon movement of the metal rods.
