Abstract
The present invention is directed to a single pass medical electrical lead. In one embodiment, the lead feature a pair of bipolar electrodes positioned along the lead body so that they are positioned in the ventricle and atrium respectively when the lead is implanted. The lead body features a 90 degree bent reinforced section. The bend has a radius of curvature approximately 13 mm and begins approximately 90 mm from the distal end. This curved section is approximately 40 mm in length when straightened. The ventricular electrodes are positioned approximately 28 mm apart. The ventricular cathode electrode is positioned at the distal end of the lead. The atrial electrodes are positioned approximately between 5-35 mm apart, with 28 mm preferred. The atrial anode is located at a position immediately adjacent and proximal the 90 degree bent reinforced section.
