    Abstract: A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment.

    Abstract: A method for delivering a self-expanding prosthetic heart valve comprises positioning the prosthetic heart valve in an annulus of a native heart valve while mounted in a radially compressed state in a delivery cylinder, the delivery cylinder coupled to a distal end portion of the torque shaft, and rotating a torque shaft coupled to the delivery cylinder. Rotating the torque shaft retracts the delivery cylinder, thereby exposing the prosthetic heart valve, allowing the prosthetic heart valve to self-expand in the native valve annulus. In some embodiments, the torque shaft is rotated by a motor disposed in a handle at a proximal end of the delivery device.
