Abstract
A system and method for determining the detachment of an embolic material using a single power supply are disclosed, wherein the determination is made by applying a DC power to an assembly with an embolic material, a sacrificial link and a guiding wire which are serially connected and repeatedly measuring a voltage and current between the assembly and the ground for a plurality of cycles and a plurality of times in each cycle; computing an average of the measured voltages and an average of measured currents; and determining the detachment of the embolic material from the guiding wire based on a change in impedance between the guiding wire and the ground, wherein the change is detected using the present average of the measured voltages, the present average of the measured currents and a previous average voltage which is previously measured for a plurality of times.
