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.
