Fault Detection System for a Stent-Graft Endoleakage Monitor

A new inductive coupling based wireless system is being developed to monitor the condition status of aortic stent-grafts. It relies on the measure of the stent-graft´s outer pressure using a capacitive sensor placed in a LC resonant circuit. The work presented herein addresses the testing of the LC sensor circuit to diagnose whether observed pressure deviations are due to defects occurring in the sensor´s inductor and capacitor or to an actual degradation of the stent-graft.
