Application No. 09/254,605
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 comprising a
low-resistive conductor;
at least two of said plurality of wires in said wire set
respectively comprising high-resistive conductors, each
of said high-resistive conductors being comprised of a
same high-resistivity material;
all wires in said plurality of wires having equal respective
diameters; and
said low-resistive conductor comprising a wire having a core
of a low-resistivity material encased in an exterior
jacket comprised of said high-resistivity material.
The examiner relies upon the following references as
evidence of obviousness:

Appellant's claimed invention is directed to a medical
electrode cable comprising a plurality of wires which form a wire
set. The plurality of wires are disposed side-by-side and
comprise a low-resistive conductor, such as silver, and at least
two high-resistive conductors, e.g., a cobalt alloy. Also, the
low-resistive conductor is encased in an exterior jacket of high-
resistive material. The electrode cable is "mainly intended to
serve as an electrical connection between an electrical
stimulation device, such as a heart stimulator, defibrillator,
