Claim 5:
6. A medical instrument comprising:
an assembly, wherein a first electronic unit is positioned within the assembly;
a housing coupled to the assembly via a pressure tight seal at a first opening of the housing, wherein a second opening of the housing is in communication with a second electronic unit, and wherein a third opening of the housing is in communication with a pressure test port; and
a pressure-sealed electrical cable comprising one or more conductors and having a proximal end and a distal end, the proximal end of the pressure-sealed electrical cable coupled to the second electronic unit and the distal end of the pressure-sealed electrical cable coupled to the first electronic unit, wherein the pressure-sealed electrical cable passes through the first and the second opening of the housing,
wherein the pressure-sealed electrical cable passes through the pressure tight seal and comprises a structure to prevent a through path for gas flow within the pressure-sealed electrical cable between the assembly and the housing, wherein the pressure tight seal is in the first opening of the housing and formed around the pressure-sealed electrical cable, wherein a second pressure tight seal is in the second opening of the housing and formed around the pressure-sealed electrical cable, wherein each of the structure, the pressure tight seal and the second pressure tight seal are sufficient to maintain a pressure during a pressure test of the medical instrument via the pressure test port.
