Analysis of critical current field distribution in tissues during electrosurgical procedures

In this paper the method of critical current field analysis in hepatic tissue is presented. The method emerges from heterogeneous electrical model of the tissue, where a powerful software package Comsol, as analysis medium, is used. The obtained results are exploitable for the analysis of probability of injury formation in sensitive tissue structures, which would enable the optimization of surgical procedures and development of more sophisticated electrosurgical devices.
