Abstract
An improved electrical connection capable of mechanical movement for providing an electrical connection between a rotatable terminal pin and an external pacer terminal casing in an improved cardiac pacer lead is disclosed. The pacer lead includes an elongated terminal pin at its proximal end that has a generally cylindrical cross-section which extends through an axial bore of an external retaining collar, a coupling and an insulating sleeve and terminates in engagement with an electrode at the distal end at the pacer lead. The retaining collar has a counterbore that defines an annular cavity between the collar and the terminal pin which accomodates an electrical connecting coil. The connection coil has a configuration wherein individual coil turns are circumferentially offset from adjacent coil turns and project radially outwardly from the axis of the coil. The coil is assembled over the terminal pin and within the collar counterbore so that the turns of the coil springly contact both the terminal pin and collar counterbore to create an electrical contact between them that allows rotation of the terminal pin within the collar.
