Patent ID: 7724148

Claim:
A pressure measurement system, comprising: a pressure sensor wire comprising an insertable portion configured to be inserted in a blood vessel of a patient's body and a pressure sensor disposed within the insertable portion at a distal end of the pressure sensor wire, wherein the pressure sensor is configured to measure pressure inside the patient; and a transceiver unit, comprising: a housing adapted to be connected to a proximal end of the pressure sensor wire; a communication module within the housing adapted to wirelessly communicate by a communication signal with a communication unit, wherein the communication unit is arranged in connection with an external device in order to transfer pressure information to the external device; and a sensor signal adapting circuitry within the housing adapted to filter, process, and format a signal received from the pressure sensor wire, wherein the communication signal, including pressure sensor values, is generated by the transceiver unit and transferred as a data stream, wherein the housing is configured to remain external to the patient's body, and wherein the sensor signal adapting circuitry within the housing comprises a calibrating section containing calibration data for the pressure sensor wire.
