ABSTRACT:
The bipolar screw-in pacing lead assembly is adapted to be mechanically secured to tissue of a body in an electrically conductive manner. The pacing lead assembly comprises an insulative tubular sheath having a distal end and a proximal end. First and second conductive members each having a distal end and a proximal end are received in and extend substantially the length of the tubular sheath. The first conductive member is insulated from the second conductive member. The pacing lead assembly further includes a distal electrode assembly at the distal end of the tubular sheath comprising a corkscrew attachment device which is electrically and mechanically connected to the second conductive member. A proximal terminal electrode assembly is coupled to the tubular sheath and includes (a) a cathode terminal pin/attachment member which is coupled by a brush contact to the second conductive member and which can be rotated to operate the corkscrew attachment device to secure the distal electrode assembly to tissue of the body and (b) a ring electrode having a brush contact adapted to make contact with the rotatable proximal end of the first conductive member.
