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.
Claims13
A medical electrode cable having a longitudinal axis, comprising:
- an exterior, tubular insulating sheath;
- a plurality of wires disposed side-by-side substantially parallel to said sheath and forming a wire set, said wire set extending helically around and along said longitudinal axis;
- one of said plurality of wires in said wire set consisting of a low-resistive conductor;
- at least two of said plurality of wires in said wire set respectively consisting of high-resistive conductors, each of said high-resistive conductors consisting of a same high-resistivity material;
- all wires in said plurality of wires having equal respective diameters;
- and
- said low-resistive conductor being a wire consisting of a core exclusively of a low-resistivity material encased in an exterior jacket exclusively of said high-resistivity material.
