Claim 12:
13. A surgical apparatus comprising a pressure-sealed electrical cable, the pressure-sealed electrical cable further comprising:
one or more conductors, each of the one or more conductors individually has an insulating jacket;
a first shield surrounding the one or more conductors;
a second insulating jacket surrounding the first shield; and
a first pressure seal formed in and around the first shield and around the one or more conductors and extending between the second insulating jacket and the insulating jacket of the one or more conductors,
wherein the second insulating jacket does not extend a full length of the pressure-sealed electrical cable exposing a first edge of the first shield and a second edge of the first shield, and the first pressure seal is formed in and around the first shield by heat shrink tubing affixed to the first insulating jacket adjacent to the first edge and the second edge, and
wherein silicon is injected into the heat shrink tubing so that a shrinking of the heat shrink tubing forces the silicon into any openings of the first shield and into any openings between the one or more conductors to form the first pressure seal.
