Abstract
A shaft for an invasive probe used for medical applications which includes a central core, a metal sheath surrounding the core and an outer elastomeric coating. A dielectric sleeve is disposed between the core and sheath for electrically isolating the core from the sheath. A dielectric spacer used in conjunction with a fitting disposed at the end of the shaft completely seals the core from other portions of the probe to protect the patient from electrical currents carried by wires within the core. The wires are also protected from damage from bodily fluids and cleaning solutions by the dielectric sleeve and spacer, since the core is sealed from the environment.
