    摘要: Biocompatible heparin-like material and surfaces thereof are made by co-polymerization of acrylic acid (AA) and 2-acrylamido-2-methyl propane sulfonic acid (AMPS) and attaching the copolymer to a suitable substrate or blending the copolymer into a suitable substrate. The material produced also possesses surface slip-properties and some decreased bacterial and platelet adherence.

    摘要: A preformed electrical connector for use with body implantable stimulators, such as heart pacemakers, having a signal generator and at least one electrical lead electrically and mechanically connected to each other through the preformed electrical connector. The connector carries at least one terminal to establish electrical contact between the signal generator and electric lead, passageways being provided in the connector body to accept and guide the signal generator feedthrough pin and electrical lead into contact with the terminal. In a preferred embodiment, the terminal is provided with intersecting bores such that the feedthrough pin and electrical lead form electrical contact within or by means of the terminal. The pin may be welded or press fit to the terminal and the lead may be attached to the terminal by means of a setscrew. The preformed connector may be mechanically fastened or fastened with an adhesive to the implantable stimulator. The connector may include one or two terminals and may then connect one or two sets of feedthrough pins and respective electrical lead wires.
