Abstract: A medical electrode cable has an exterior, tubular insulating sheath containing a number of side-by-side wires arranged substantially parallel to the sheath and helically proceeding around and,along a longitudinal axis. At least one of the wires is a low-resistivity conductor, and at least two of the wires are high-resistivity conductors. All of the wires have equal diameters. The low-resistivity conductor is a wire having a core of a low-resistivity material encased in an exterior jacket of the same high-resistivity material which forms the high-resistivity conductors.
