Abstract
A biological tissue monitoring system has control circuitry programmed or configured to monitor an impedance of biological tissue. The control circuitry is programmed or configured to receive or determine an impedance measurement of the biological tissue in response to power delivered to the biological tissue at a plurality of frequencies and a plurality of time points, and adjust or cause to be adjusted the power delivered to the biological tissue at a subsequent time point based on the impedance measurement at the plurality of frequencies and the plurality of time points.
