Abstract
A transvenous endocardial lead comprises an elongated flexible body member encompassing an electrical conductor which has an electrode at its distal end. A stabilizer adjacent the distal electrode extends outwardly from the flexible body member by a distance no greater than approximately one-half of the shortest distance between a longitudinal axis and the outer peripheral surface for minimizing dislodgment of the distal end from an intended implanted position into the myocardial tissue of the heart and for preventing penetration of the distal end of the flexible body member into the myocardial tissue. The stabilizer may be employed in conjunction with conventional active or passive fixation members and may take a variety of forms.
