Actively Controllable Stent, Stent Graft, Heart Valve and Method of Controlling Same
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.

Abstract of the DisclosureThe present invention provides an apparatus and method for use in processing semiconductor workpieces. The new apparatus and method allows for the production of thinner workpieces that at the same time remain strong. Particularly, a chuck is provided that includes a body, a retainer removeably attached to the body and a seal forming member. When a workpiece is placed on the chuck body and the retainer is engaged to the body, a peripheral portion of the back side of the workpiece is covered by the retainer while an interior region of the back side of the workpiece is exposed. The exposed back side of the workpiece is then subjected to a wet chemical etching process to thin the workpiece and form a relatively thick rim comprised of semiconductor material at the periphery of the workpiece. The thick rim or hoop imparts strength to the otherwise fragile, thinned semiconductor workpiece. Semiconductor workpieces made according to the present invention offer an improved structure for handling thinned wafers in conventional automated equipment. This results in improved yields and improved process efficiency.
