Abstract
A method is provided to seal and cut biological tissue. An alternating current (AC) scaling signal is imparted between a set of sealing electrodes. An AC cutting signal is imparted between a set of cutting electrodes in response to a biological tissue impedance between the sealing electrodes reaching a first impedance threshold value. The AC scaling signal is halted at an end of a time interval, beginning while the AC cutting signal is imparted between the cutting electrodes, in response to impedance of the biological tissue disposed between the set of sealing electrodes reaching a second impedance threshold value.
