Patent ID: 8187195

Claim:
A sensor wire assembly for measuring a physiological variable in a body, said assembly comprising: a sensor element configured to measure the physiological variable and to generate a sensor signal representative of said variable; a guide wire having said sensor element at its distal portion, and adapted to be inserted into the body in order to position the sensor element within the body; a wire connector provided with a guide wire receptacle tubing in which a proximal end of said guide wire is inserted, wherein a number of connector sockets are arranged along the tubing to be electrically connected to electrical connection points along an inserted part of the guide wire; and a connecting cable configured to directly connect said wire connector to an external physiology monitor, wherein the wire connector comprises a wire connector casing that encloses sensor signal adapting circuitry, wherein the sensor signal adapting circuitry comprises a programmable sensor conditioning unit, a calibration unit, an energy device, and an output amplifying unit, wherein the assembly is configured such that the sensor signal is provided to the sensor signal adapting circuitry, which is adapted to automatically generate an output signal, related to the sensor signal, in a standardized format such that the measured physiological variable is retrievable by said external physiology monitor via said connecting cable, and wherein the wire connector casing is configured such that, in use, all information delivered to and transmitted from the wire connector is conveyed only by the guide wire and the connecting cable.
