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.

An alternative embodiment employs a resilient spring to firmly hold the ring electrode in electrical contact with the connector block.

Abstract: An electric contact device for an electrical connection of electroconductive connectors comprises a row of interconnected contact elements which are joined together by at least one continuous band-shaped or wire-shaped spring element. Each contact element is provided with at least one opening through which the spring element extends. The opening provides for fixing of the contact element which, in an unstressed condition, extends at an angle maximum 45.degree. relative to the plane of the spring element.

This permits to assemble the device with larger tolerances for spacing between the contact elements. Preferably, the edges of the contact elements have a high electric conductivity.

Abstract: The method relates to manufacturing contact spring sockets with a plurality of radially inward bowed contact springs clamped at one end in an approximately cylindrical socket body, formed by a thin-walled deformable sleeve. After introduction of the straight contact springs into the socket body from one socket end, they are made fast by deformation of the socket material and their free ends are brought into supporting abutment on an annulus. This is associated with a mandrel for assisting assembly, which passes through it and which is during manufacture introduced co-axially into the socket body and finally withdrawn from it. Subsequently the mandrel together with the annulus is introduced into the socket body. The contact springs are then, by applying axial pressure on their ends, converted into a shape bowed into the interior of the socket until they abut the mandrel.
