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.

Abstract: A connection, in particular of the miniature type for providing oblique connections at angles which may be selected over a wide range of angles on request. Said connections serving to put a conductor wire (3) into electrical connection with a conductor strip (4) of an electrical apparatus by gripping the wire between a wire-gripping surface (41) provided on the strip and a corresponding parallel, internal, wire-gripping surface (10) of a cage (1) which surrounds the strip, said grip being provided by the action of a clamping screw (2) screwed into the cage and bearing against the opposite surface of the strip from its wire-gripping surface. The clamping screw is disposed obliquely relative to the wire-gripping surfaces and its end presses directly on said opposite surface (22); the cage (1) includes at least one lateral screw-backing element (11) in the vicinity of the end (21) of the screw where it is pressed against the strip.
