Abstract
A medical temperature sensing probe including a temperature responsive device having electric contacts and insulated electric conductors having one end electrically connected to a respective one of the electric contacts. Each conductor comprises a carbon-fiber tow having low thermal conductivity and plated with an electrically conductive metal. The metal plated tows are X-ray translucent and have low thermal conductivity to minimize thermal conduction of heat to or from the temperature responsive device.
Claims11
A medical temperature sensing probe including a temperature responsive device having electric contacts and insulated electric conductors having one end electrically connected to a respective one of the electric contacts, the improvement wherein each conductor comprises a carbon-fiber tow having low thermal conductivity and less than two thousand fibers and plated with an electrically conductive metal in an amount such that the metal plated tow is at least X-ray translucent, the metal plating being 20% to 40% by weight of the metal plated carbon fiber tow.
A medical temperature sensing probe including a thermistor having electric contacts and insulated electric conductors having one end electrically connected to a respective one of the electric contacts, the improvement wherein each conductor comprises a pan based carbon-fiber tow having about 800 to 1200 fibers and plated with an electrically conductive metal in an amount such that the metal plated tow is at least X-ray translucent, the metal plating being 20% to 40% by weight of the metal plated carbon-fiber tow.
