Abstract
An implantable electrical lead of the type having a rigid, insulative electrode head carrying an advanceable helical electrode. The electrode head is mounted to an elongated insulative lead body less rigid than said electrode head and which carries an extensible conductor coupled to the helical electrode and an inextensible conductor mechanically coupled to the proximal end of the lead. A second electrode is mounted to said lead body adjacent the electrode head and is coupled to the inextensible conductor. The inextensible electrical conductor is mechanically coupled to the electrode head such that poximally directed traction forces applied to the proximal end of the lead body are applied to the head by the inextensible conductor and not by the second electrode.
