1. A method of delivering electrical energy to an electrosurgical device having jaws with corresponding electrodes, the method comprising:
delivering an electrotherapeutic signal to biological tissue to the electrosurgical device;
measuring an impedance of the biological tissue;
measuring an electrosurgical device sealing parameter, wherein the electrosurgical device sealing parameter includes a temperature of the jaws; determining an adjusted impedance based on a relationship between the temperature of the jaws and the measured impedance; and delivering an adjusted electrotherapeutic signal to the biological tissue to the electrosurgical device based on the adjusted impedance.
