ABSTRACT:
A connector block assembly for electrically connecting a proximal ring electrode of a bipolar pacemaker lead to the pacemaker. The connection is made in a way that maintains secure electrical contact and that prevents the delicate proximal ring electrode from being damaged or deformed. The pacemaker includes a connector block having a channel therethrough into which the proximal ring electrode is inserted. A C-ring is sandwiched between the ring electrode and an inner wall of the connector block's receiving channel. A setscrew adjustably forces the C-ring against the ring electrode. Mechanical stop means limit the transverse movement of the C-ring, thereby preventing the ring electrode from being deformed, while still maintaining a firm grasp of the ring electrode between the C-ring and the connector block. An alternative embodiment employs a resilient spring to firmly hold the ring electrode in electrical contact with the connector block.
