Abstract:
1. A medical guide wire assembly comprising: a guide wire having a proximal end and a distal end, the guide wire comprising a core wire running essentially along the entire guide wire; at least one physiological parameter sensor; an elongated connector part at the proximal end of the guide wire, having connection electrodes, configured for insertion into a connector housing provided with an elongated tubing configured to achieve electrical and mechanical connection to the elongated connector part; and sensor signal processing circuitry arranged for connection with the at least one physiological parameter sensor configured to generate a processed sensor signal in response to a sensed parameter, wherein the sensor signal processing circuitry comprises a modulation unit arranged to modulate the processed sensor signal and to generate a modulated sensor signal; wherein the assembly includes exactly two micro-cables that are connected to the sensor signal processing circuitry, the micro-cables running along the guide wire and being connected to connection electrodes of the connector part, and wherein either (i) the core wire is configured to be actively used for transferring the processed and modulated sensor signal to the connector housing, or (ii) the two micro-cables are configured to be actively used for transferring the processed and modulated sensor signal to the connector housing.
