#$%^&*AU2018203853A120180621.pdf#####ACTIVELY CONTROLLABLE STENT, STENT GRAFT, HEART VALVE AND METHOD OF CONTROLLING SAME ABSTRACT A method for implanting a stent, which comprises: contracting to a reduced implantation size with a delivery system having drive wires (750), the stent having a selectively adjustable assembly with adjustable elements operatively connected to the drive wires such that, when the adjustable elements are adjusted by the drive wires (750), a configuration change in at least a portion of the stent occurs； inserting the contracted stent into a native annulus in which the stent is to be implanted； rotating the drive wires (750) with the delivery system to forcibly expand the stent； while rotating the drive wires (750), determining with the delivery system a torque applied to the drive wires (750)； stopping rotation of the drive wires (750) based upon a value of the determined torque when the stent contacts the native annulus and has a first diameter； and after the stent contacts the native annulus, repeatedly rotating and stopping rotation of the drive wires (750) to incrementally expand the stent from the first diameter to a second, final diameter.
