Abstract
Epicardial pacing lead for affixation to epicardial heart tissue either onto the forward facing portion of the heart or behind the heart during thoracic surgery. A stylet controls a helical fixation screw in an electrode head of the pacing lead in that the stylet is turned thereby advancing the helical fixation screw beyond the planar surface of the electrode head. The epicardial pacing lead includes two embodiments which can be used in the unipolar mode of operation and one embodiment which can be used in the bipolar or unipolar mode of operation. The epicardial pacing lead requires no special tools and can be applied to the epicardial tissue with the use of surgical forceps or clamps. The pacing lead can be connected to a pulse generator located adjacent to the epicardial tissue under the skin and can be used for atrial or ventricular pacing.
