1. 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, andwherein the sensor signal adapting circuitry within the housing comprises a calibrating section containing calibration data for the pressure sensor wire.

Abstract
Pressure measurement system comprising a pressure sensor wire with a pressure sensor to measure pressure inside a patient, and to provide measured pressure data to an external device. The pressure sensor wire is adapted to be connected, at its proximal end, to a transceiver unit that is adapted to wirelessly communicate via a communication signal with a communication unit arranged in connection with an external device, in order to transfer measured pressure data to the external device. The pressure data to be transferred is generated by the transceiver unit and transferred as a data stream. Preferably, the communication signal is a radio frequency signal.
