摘要:
A method for implanting a stent includes contracting a self-expanding/forcibly-expanding stent of a shape-memory material set to a given shape to a reduced implantation size with a delivery system having drive wires. The stent has 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, a configuration change in at least a portion of the self-expanding stent occurs. The contracted stent is inserted into a native annulus in which the stent is to be implanted. The drive wires are rotated with the delivery system to forcibly expand the stent into the native annulus. While rotating the drive wires, a torque applied to the drive wires is determined with the delivery system. Rotation of the drive wires is stopped based upon a value of the determined torque.
