Abstract: A transmitter unit with a detachable energy source is provided for a sensor guidewire. The transmitter unit is adapted to be connected to a proximal end of a sensor guidewire provided, at its distal end, with a sensor to measure a physiological parameter inside a patient. In some embodiments, the transmitter unit is adapted to wirelessly communicate by a communication signal with a communication unit, arranged in connection with an external device, in order to transfer measured physiological data to the external device. The detachable energy source can be a battery pack provided with connecting electrical connecting surfaces. Preferably, the connection is protected from penetrating fluids by a protective seal.

Abstract: A pressure sensor wire assembly measures pressure inside a body of a patient. The assembly comprises a pressure sensor element for measuring pressure and to generate a pressure sensor signal representative of the pressure, and a pressure sensor wire having the pressure 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 sensor signal adapting circuitry is an integrated part of the assembly, wherein the pressure sensor signal is applied to the adapting circuitry which is adapted to automatically generate an output pressure signal, related to the sensor signal, in a standardized format such that the measured pressure is retrievable by an external physiology monitor. The assembly further comprises an external pressure sensor to measure the pressure outside the patient's body and to generate external pressure values in dependence thereto.
