IPC: H01P3/08
Filed: 1989-02-17
Abstract: PURPOSE:To optimize characteristics after manufacturing IC by forming a line, consisting of Schottky metal, as a distributed constant line and providing semiconductor conductive layers intersecting this line, consisting of Schottky metal, and ohmic metal electrodes in contact with these semiconductor conductive layers. CONSTITUTION:A line 12 consisting of Schottky metal and electrodes 13, 14 consisting of ohmic metal are formed on a semiconductor substrate 11, 15, 16 are semiconductor conductive layers formed in the surface part of the semiconductor substrate 11. One ends of the conductive layers 15, 16 intersect the Schottky metal line 12, and the other ends are formed to be superposed on the ohmic metal electrodes 13, 14. Therefore, if a line in the part, where subsequent adjustment is supposed to become necessary, is caused to be the Schottky metal line, and is connected to the ohmic metal electrodes via the semiconductor conductive layers, characteristics of that line can be adjusted from outside after the manufacture of an IC, by the level of DC potential applied to the semiconductor conductive layers via the ohmic metal electrodes.

Title: Vascular stent
Inventor: GIANTURCO CESARE
IPC: A61M29/02
Filed: 1988-02-19
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.
