1. An implantable electrical lead comprising:

  • an insulative rigid electrode head carrying a helical electrode;

    an elongated insulative lead body less rigid than the electrode head, having a proximal end and a distal end coupled to the electrode head and carrying an inextensible conductor therein coupled to the proximal end of the lead body;

    a second electrode mounted to said lead body, adjacent the electrode head; and

    a conductive sleeve electrically and mechanically coupled to the inextensible conductor and to the second electrode so that proximally directed traction forces applied to the lead body are applied by the inextensible conductor directly to the electrode head.
