1. A method for restoring a defective heart valve in a patient, the method comprising the steps of:
manipulating a delivery device loaded with a radially expandable prosthetic heart valve in a radially compressed configuration, the prosthetic heart valve having a stent frame to which a valve structure is attached, the delivery device including a delivery sheath constraining the prosthetic heart valve in the radially compressed configuration, an outer stability shaft coaxially received over the delivery sheath and terminating proximal of the prosthetic heart valve with the delivery device in a delivery configuration, a handle including an actuator mechanism coupled to the delivery sheath, and an adjustment device coupled to the handle, to guide the prosthetic heart valve through the patient's vasculature and into the defective heart valve by moving the handle, which correspondingly moves the adjustment device, the delivery sheath, and the stability shaft;
adjusting the location of the prosthetic heart valve by manipulating an adjustment mechanism on the adjustment device, wherein manipulating the adjustment mechanism causes the handle and the delivery sheath to move relative to the adjustment device and the outer stability shaft; and
withdrawing the delivery sheath from the prosthetic heart valve by actuating the actuator mechanism such that the delivery sheath slides relative to the outer stability shaft and the handle to release the prosthetic heart valve from the delivery sheath such that the prosthetic heart valve self-expands into engagement with the native heart valve.
