Abstract
A novel flexible and highly fatigue resistant neural lead is provided having a body with multiple lumens, one of which may receive a stiffening stylet, and the others of which serve as conduits for bundle stranded wire conductors which make contact with ring electrodes at the distal end of the lead. The ring electrodes will be constructed according to a novel technique in which the body of the lead is etched or milled to provide notches and the ring electrodes are formed by enplacing a C-shaped conductor over the notch and closing it into place to provide an isodiametric lead construction.
