  • Pacemaker connector system
    Patent number: 4848346
    Abstract: A pacemaker connector system for the coaxial heart lead of a bipolar pacemaker consists of two connector block assemblies housing circular springs which circumferentially grip the central and outer terminals of the lead. Protruding ends of the springs are covered by rubber septum buttons which, when depressed, open the spring interiors to allow insertion of the heart lead. The problems associated with set screw systems are eliminated, and improved mechanical and electrical contact over other types of spring systems is provided.
