Abstract
A measurement system may comprise a sensor wire and a transceiver unit. The sensor wire may comprise an insertable portion configured to be inserted in a blood vessel of a patient's body and a sensor disposed within the insertable portion at a distal end of the sensor wire. The sensor is configured to measure a parameter when inserted inside the patient. The transceiver unit may comprise: a housing adapted to be connected to a proximal end of the sensor wire; and a first communication module within the housing adapted to wirelessly communicate by a communication signal with an external second communication module in order to transfer information to the external second communication module.
Claims21
A measurement system, comprising:
- a sensor wire comprising an insertable portion configured to be inserted in a blood vessel of a patient's body and at least one sensor disposed within the insertable portion at a distal end of the sensor wire, wherein the at least one sensor is configured to measure a parameter when inserted inside the patient and to send a sensor signal;
- and
- a transceiver unit, comprising:
- a housing having an aperture through which a proximal end of the sensor wire is to be inserted;
- a circuit configured to modify the sensor signal so as to obtain a modified sensor signal,
- a first communication module within the housing adapted to wirelessly send the modified sensor signal to an external second communication module,
- wherein the sensor wire is fixed to the housing of the transceiver unit such that, as the transceiver unit is rotated along its longitudinal axis, the sensor wire is also rotated.
