Abstract: Apparatus is disclosed for reading phase encoded digital data from a nine-track magnetic tape which apparatus includes timing circuitry for deriving a clock signal from the recorded data. A portion of the timing circuitry is associated with each track on the tape and automatically accomodates, without generating errors, phase changes in the derived clock signal in that track caused by speed variations in the magnetic tape transport and due to bit shifts caused by certain data patterns.Tape transport speed variations are sensed and the derived clock rate is corrected by a digital phase-locked loop which uses a counter that is clocked at a constant rate to determine the timing "window" during which the circuitry looks for signal transitions on the magnetic tape. A running average of the count remaining in the counter at the time when a transition actually occurs is used to adjust the counter starting value until equilibrium is established.The circuitry accomodates clock signal phase changes caused by bit shifting by calculating an expected arrival time for a data transition and varying the width of the timing window depending on whether the data transition is received either prior to or subsequent to the expected arrival time.

Abstract: A wire stent (10) for insertion and expansion into a passageway comprises a plurality of curved sections that are formed into a generally circular configuration. Adjacent curved sections are joined by a bend or cusp (13), so that a series of alternating opposing loops (15, 16) are formed. The wire stent as formed has a cylindrical shape with a longitudinal opening through which a folded balloon catheter is inserted. The opposing loops are tightly contracted about the catheter so that the cylindrical shape has an overlapping region in which portions of adjacent loops longitudinally overlap. The loops are arranged so that when the balloon catheter is inflated, adjacent loops diverge circumferentially relative to each other, thereby decreasing the overlapping region while increasing the diameter of the cylindrical shape (24, 25). As the diameter of the cylindrical shape increases, the wire stent contacts the surface of a passageway in which the stent is inserted. In a method of the present invention, the wire stent (10) is fabricated from a wire formed into a planar serpentine configuration (30). The wire is centered over a semi-cylindrical trough (43) in a flat plate (40) and then pressed into the trough by a forming bar (45) so that a portion of the wire assumes the semi-cylindrical shape. A pulling tool (47), having a hook (47a) at one end, is engaged at the hook with the exposed loops (13) of the serpentine configuration for pulling the exposed loops over the exposed portion of the forming bar to form a generally cylindrical shape from the wire. Once the wire is extracted from the trough and the forming bar is removed, a folded balloon catheter (22) is inserted through the cylindrical shape and the wire is tightly pressed about the catheter.
