Patent ID: 7860553

Claim:
Medical apparatus comprising: a probe, having a proximal end and a distal end, which is adapted for insertion into the body of a subject, said probe comprising: a sensor, which outputs a sensor signal; a first microcircuit, which stores first calibration data with respect to the sensor; and a first connector at the proximal end of the probe, electrically coupled at least to the sensor; a probe adapter configured to be detachably connected to the probe, said probe adapter comprising: a second connector, which is arranged to mate with the first connector of the probe; a signal processing circuit, which is coupled to process the sensor signal so as to output a processed signal; a second microcircuit, which stores second calibration data with respect to the signal processing circuit; a microcontroller, which is arranged to receive the first calibration data from the first microcircuit of the probe and second calibration data from second microcircuit of the probe adapter, respectively, and to compute combined calibration data based on the first calibration data and the second calibration data; and a third connector, electrically coupled at least to the signal processing circuit; and a console, comprising: a fourth connector, which is arranged to mate with the third connector; and signal analysis circuitry, which is coupled to receive at least the processed signal from the fourth connector and is arranged to analyze the processed signal using the combined calibration data provided by the probe adapter.
