Patent ID: 8216151

Claim:
A pressure sensor wire assembly for measuring pressure inside a body of a patient, comprising: a pressure sensor element configured to measure pressure and to generate a pressure sensor signal representative of the measured pressure; a pressure sensor wire, the pressure sensor element being located at a distal portion of the pressure sensor wire, wherein the pressure sensor wire is adapted to be inserted into the body in order to position the pressure sensor element within the body; a sensor signal adapting circuitry, being an integrated part of the assembly, wherein the sensor signal adapting circuitry is configured, when the pressure sensor signal is applied to the sensor signal adapting circuitry, to automatically generate an output pressure signal, related to the pressure sensor signal, in a standardized format such that the measured pressure is retrievable by an external physiology monitor; an external pressure sensor arranged in the assembly, configured to measure an external pressure outside the patient's body, and configured to generate an external pressure value in dependence on the external pressure; a pressure compensator in the assembly configured such that, when the external pressure value is applied to the pressure compensator, the pressure compensator is adapted to generate a compensation value reflecting external pressure variation during a measurement procedure, wherein the output pressure signal is compensated by the compensation value prior to the output pressure signal being sent to the external physiology monitor; a transceiver unit; and a communication unit, wherein the external pressure sensor is arranged in the communication unit, wherein the pressure sensor wire is adapted to be connected at its proximal end to the transceiver unit, wherein the transceiver unit is configured as a torque device with a guiding mechanism configured to guide the pressure sensor wire during insertion into the patient, wherein the transceiver unit is adapted to wirelessly communicate via a communication signal with the communication unit, and wherein the communication unit is connected to the external physiology monitor in order to transfer the output pressure signal to the external physiology monitor.
