Abstract
An implantable defibrillation lead with steerable characteristics, allowing the lead to be more easily placed within the coronary sinus. The lead comprises an elongated lead body having a proximal end and a distal end. Adjacent the distal end, there is an electrode, preferably a coiled defibrillation electrode placed on the exterior of the elongated lead body. The distal end of the lead body has a permanent set or bend. A torque tube, extending through a lumen in the lead body from the proximal end of the lead to an anchor block adjacent the distal end of the lead, can be rotated by a physician to orient the bend in the lead. A cable passes through the torque tube from the proximal end of the lead through the anchor block to the distal end of the lead. This cable is affixed to a wall of the lumen, preferably in the direction of the bend. Pulling on the cable temporarily changes the bend in the distal end of the lead.
