A probe (

20

) for insertion into the body of a subject, the probe (

20

) having distal (

22

) and proximal ends, and including an electronic microcircuit (

90

), which stores information relating to calibration of the probe (

20

). Preferably, the microcircuit (

90

) stores a calibration code, which is encrypted. Alternatively or additionally, the microcircuit (

90

) stores a usage code, which controls availability of the probe (

20

) to a user thereof. Preferably, the probe (

20

) includes access control circuitry (

90

) that allows the usage code to be changed so as to reduce the availability of the probe (

20

), but not to increase the availability thereof.
