Abstract

Systems for controlling the power supplied to an electrosurgical probe. The systems may be used to monitor electrode-tissue contact, adjust power in response to a loss of contact, and apply power in such a manner that charring, coagulum formation and tissue popping are less likely to occur. The systems used to assess and monitor electrode tissue contact and to control power can be based on testing the value of the impedance at two different test frequencies, the actual temperature, the predicted temperature.
