Abstract

A system for monitoring and/or controlling tissue modification during an electrosurgical procedure is disclosed. The system includes a sensor module and a control module operatively coupled to the sensor module and configured to control the delivery of electrosurgical energy to tissue based on information provided by the sensor module. The sensor module further includes at least one optical source configured to generate light and at least one optical detector configured to analyze a portion of the light transmitted through, and/or reflected from, the tissue.
