Method and system for controlling an output of a radio-frequency medical generator having an impedance based control algorithm

Abstract

A system for performing an electrosurgical procedure at a surgical site is disclosed. The system includes a sensor configured to continually sense an electrical and/or a physical property of tissue at a surgical site and to generate a sensor signal as a function thereof. The system also includes a control module configured to process the sensor signal using a processor, an algorithm, and a map having one or more predetermined values. The control module is further configured to compare the sensor signal to a predetermined level to determine reliability of the sensor signal and to signal an electrosurgical generator in response to a reliable sensor signal such that the electrosurgical generator enters energy control mode, wherein the electrosurgical generator matches an output of the control signal with a predetermined value from the map.

Dependencies are inferred from the claim text.
