Title
(EN) CATHETER CALIBRATION AND USAGE MONITORING SYSTEM
(FR) SYSTEME DE CONTROLE DE L'ETALONNAGE ET DE L'UTILISATION D'UN CATHETER
Abstract
(EN)
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.
