Abstract:
1. A stimulation electrode lead for connecting to an electrotherapy device such as a pacemaker or a defibrillator, the stimulation electrode lead being configured for intraluminal placement within a blood vessel or within a heart of a patient, said stimulation electrode lead comprising: a proximal end; a distal end; an electrode lead plug at the proximal end of the stimulation electrode lead; stimulation electrodes at the distal end of the stimulation electrode lead, the stimulation electrodes having an electrically conductive outer surface and being electrically connected to the electrode lead plug; at least one distal electrode support member at the distal end of the stimulation electrode lead, said support member supporting at least one electrode and being connected by a conductor link to a distal end of a first, extended portion of the electrode lead, wherein the conductor link is preformed such that, when in a relaxed state, the conductor link is not extended and may be elastically extended; a guide wire extending from the proximal end to the distal end of the stimulation electrode lead, wherein the conductor link does not provide a lumen for the guide wire, a lumen of the first, extended portion of the electrode lead, wherein said lumen leads at the distal end of the first, extended portion of the electrode lead into a distal opening through which said guide wire may exit the stimulation electrode lead; and a longitudinal opening of the distal electrode support member through which a distal end of said guide wire may enter the distal electrode support member.
