SYSTEMS AND METHODS FOR ABLATING TISSUE WHILE MONITORING TISSUE IMPEDANCE

摘要

2106408 9308757 PCTABS00021 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.
