Abstract
In one aspect of the present invention, a cardiac lead is provided that includes a connector for coupling to a cardiac stimulator that has a first rotatable member, and a tubular insulating sleeve that has a first end coupled to the connector and a second end. A tip assembly is coupled to the second end. The tip assembly has a second rotatable member. A coiled wire is coupled between the first rotatable member and the second rotatable member. The coiled wire is composed of a shape-memory material and is operable to transmit torque between the first rotatable member and the second rotatable member. Where the lead is provided with a bend, the shape-memory coiled wire retains a straight set, enabling smooth rotation of a fixation corkscrew without precession of the lead tip.
