title: Inductive coupling system for endovascular aneurysm repair monitoring.
abstract: Endoleaks are one of the major concerns in the long-term follow-up of endovascular aneurysm repair treatment (EVAR). Therefore, periodic monitoring is required to detect eventual damages in an implanted stent-graft. A monitoring system for post EVAR procedure based on inductive-coupling which avoids the need to resorting to more complex biomedical imaging systems is presented here. Endoleaks are detected with capacitive pressure sensors placed in the stent-graft and monitored externally after the measure of the oscillation frequency provided by the LC circuit created by sensors and inductive coupling.
