Abstract: Abstract A multi-layer circuit board comprised of two or more circuit  board  substrates  shaped  by  injection  molding with mating interconnecting pins and holes and banded together  with  an  electrically insulated  adhesive material.   Circuit leads are provided on both sides of each  substrate  recessed  into  channels  formed  in  the surface  of  the  substrate  during  the  molding  process.          Electrical  interconnnection  of the layers  of  circuitry occurs  where  the  conductive  materials  of the  circuit leads passes down through component lead holes axially located  in  the  interconnecting  pins  and  around  the exterior  of the interconnecting pins where contact is made  with  the  conductive  material  coating  on  the interior of the interconnecting holes.     A method of making the multi-layer board includes injection  molding  the  substrates in  a suitable shaped mold, plating  substantially  all of the  surface  of the substrates with the conductive material, masking with a plating  resist, plating  again  with conductive material, plating  with  an  etch  resistant  contact  material, removing the plating resist and flash-etching to remove the conductive material initially plated and masked by the plating  resist so as to define the circuit leads.          The preferred method uses a roller to apply the plating resist to some surfaces of the substrates.

IPC: A61M29/02
Filed: 1988-03-10
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.

Abstract: A hydraulic door opening or closing device comprises a hydraulic fluid pump motor (7) having two ports connected to each end of integral dual manifold (8, 9) and operating cylinder apparatus (10) by way of two branch fluid lines (11, 12). One branch line is fluidly connected to a particular end of the operating cylinder by way of a directional flow valve (17, 18). The other branch line to the same end of the cylinder is fluidly connected to the cylinder by way of an associated manifold (8, 9). Fluid communication with the cylinder through the manifold (8, 9) is accomplished by providing a plurality of valved openings (21-30) linearly disposed along the end of the cylinder between the manifold (8, 9) and the cylinder (10). As a piston (14) of the operating cylinder (10) passes these openings, a door coupled to the piston (14) is automatically slowed as fluid on the drive side of the piston is returned through the openings to the hydraulic fluid pump (7). A simplified control circuit coupled to the device provides three modes of operation, an opening mode, a closing mode and a reversing mode from door opening to door closing.
