Abstract (en)
[origin: WO9308757A1] Systems (10) for ablating tissue measure the current and voltage delivered to the associated electrode assembly (16) and generate measured current and voltage signals. The systems (10) divide the measured voltage signal by the measured current signal to derive a measured tissue impedance signal. The systems (10) perform control functions based upon the measured tissue impedance signal.
