Abstract
A medical electrode for intracorporeal electrical stimulation of body tissue, particularly for intracardial stimulation of heart tissue, includes an electrode cable having an elongated, flexible conductor covered with insulation, and terminating at one end with an electrode head for contact with body tissue. An opposite end of the cable is connectable to a source of therapeutic electrical energy. The exterior surface of the insulation is provided with a helical element winding around a substantial portion of the length of the cable between the opposite ends. The helical element may be a thin-like projection, or a groove. A device for rotating the cable during implantation causes the cable, by virtue of the helical element, to be advanced through a vein.
