Assignee: GYRUS ACMI, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 6:
7. A surgical system comprising:
a control circuit; and
an output circuit coupled to the control circuit and configured to deliver electrosurgical energy to an output terminal for delivery to a patient, the output terminal configured to couple to an electrosurgical device having two jaws with corresponding electrodes,
wherein the control circuit is configured to:
initiate a timer in response to a delivery of electrosurgical energy to biological tissue in electrical communication with two electrodes of the electrosurgical device;
after the timer has met a time limit, compare a rate of change of impedance of the biological tissue to a first threshold value;
continue the delivery of electrosurgical energy when the rate of change of impedance is less than the first threshold value; and
reduce the delivery of electrosurgical energy when the rate of change of impedance is greater than or equal to the first threshold value and less than a second threshold value.
