1. A method for implanting a stent, which comprises:

  • contracting a stent to a reduced implantation size with a delivery system having drive wires, 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, 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 with the delivery system to forcibly expand the stent;

    while rotating the drive wires, determining with the delivery system a torque applied to the drive wires;

    stopping rotation of the drive wires 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 to incrementally expand the stent from the first diameter to a second, final diameter.
