Abstract: A method of making an implantable electrode array, adapted for insertion into a cochlea, provides stability relative to the electrode contact direction. In-line electrodes are spaced-apart along one side of a flexible carrier. The structure of the electrode array facilitates bending of the array with the electrode contacts on the inside of the bend, yet deters flexing or twisting of the array in other directions. The electrode contacts preferably are each made from two strips of metal, arranged in a "T" shape (top view). During assembly, all of the "T" strips are held in position on an iron sheet. Two wire bundles are formed that pass along each side of each "T". The leg of each "T" is folded over to pinch at least one of the wires from one of the wire bundles therebetween. This pinched wire is then resistance welded to the strip. The sides of the "T" are then folded up and touch or nearly touch to form a ".DELTA." shape (side view). The wire bundles going to more distal electrodes pass through the ".DELTA.

The second hollow tubing is interference fitted onto the terminal and an end of the high voltage wire is inserted into the open end of the first tubing. The wire end is soldered to the first tubing and the second tubing is soldered to the terminal. An abundance of solder is used for causing the solder to flow outwardly from the ends of the tubings to form a continuous well-wetted shape of solder having smooth and rounded surfaces for avoiding concentrated electric fields and attendant electrical discharges.

Abstract: A method, machine and termination for connecting two or more insulated wire ends comprises placing them in a metal tube held between fusing electrodes. The electrodes are shaped to deform the tube and wires therein with the application of fusing pressure. During fusing, pressure builds first to press the assembly together, then heat and current are applied as the tube and internal wires are compressed. Fusing current first flows from a longitudinal region of the tube equally in both direction through the tube metal to soften the tube and distribute the fusing heat broadly. As the wire insulation is burned off or flows away, current also passes through the bare wire ends to aid the fusing process. For tinned copper tubes, some of the inside tin layer flows to wet copper surfaces and dissolve copper impurities. Some tin flows to seal small spaces between the fused wires. Some of the tin on the outside surface and inside surface of the tube may vaporize.

Abstract: Method and apparatus, by which the relative displacement between molten solder and a terminal pin is caused and further, a coating formed on an end portion of a coil is removed by molten solder and thus the terminal portion is firmly soldered to the terminal pin after removing the coating. In contrast, in the case of conventional soldering method, when a terminal pin, which is provided on a terminal base and has an end portion of a coil wound therearound, is dipped in molten solder contained in a solder bath, there is caused no relative displacement between the pin and the molten solder. Thus, sometimes, the coating formed on the coil still remains, so that the soldering connection between the terminal pin and the coil is not sufficiently achieved. However, in accordance with the method and apparatus of the present invention, the firm connection therebetween is achieved. Consequently, the reliability thereof is enhanced.

Abstract: In particular to connect wires insulated with highly heat-resistant lacquer to terminal elements, the winding wire has hitherto been wrapped around a terminal element and connected mechanically and electrically at at least one connection point by the local application of energy with the removal of the insulation. During winding around the terminal element, the winding end is held under pretension and simultaneously vibrations, in particular in the ultrasonic region, are coupled into the winding wire/terminal element system at the connection point to apply energy. Preferably, the vibrations are coupled into the wire outside the connection point. As a result of the fact that the vibrations propagate via the tensioned wire and bring about a relative movement between winding material and terminal element, an insulating layer can be broken up at least partially and the electrical connection to the terminal element is made by ultrasonic welding.

Abstract: The terminal portion 83 of a contact 82 is of a groove type, with a larger diameter than the lead wire diameter, and includes small holes 84 drilled and installed in the bottom of the groove. By such a construction, when the solder 19 flows in between the terminal portion 83 and the lead wire by the surface tension, the air between the terminal portion 83 and the lead wire discharges through the small holes 84, thus preventing formation of an air layer between the terminal portion 83 and the lead wire. The holes 84 permit solder to enter the holes to discharge the air, but are sufficiently small to prevent solder from flowing therethrough and dripping out of the groove. By observing whether or not the solder has flowed into the small holes 84 it is possible to confirm whether the solder has entered the clearance between the lead wire and the terminal.
