Abstract
A temporary implantable medical electrical lead includes a conductor extending along a proximal, extracorporeal length and a distal, subcutaneous length of the lead. Electrically isolated first and second wire filars of the conductor are wound to form an elongate lumen of the lead. First and second electrodes are mounted directly onto the conductor, along the subcutaneous length, and each is directly coupled to the corresponding filar. A fixation member is attached to a tubular member, which is conformed to an outer surface of the conductor so as to only cover the conductor along the subcutaneous length, leaving the outer surface exposed along a portion thereof, adjacent to the extracorporeal length. When the lead is implanted, the fixation member holds the subcutaneous length in a relatively fixed location, and fluid communication exists between the outer surface of the conductor and the lumen of the lead.
