ENERGY-BASED ABLATION COMPLETION ALGORITHM

摘要

An electrosurgical generator is disclosed. The generator includes sensor circuitry configured to measure voltage and current delivered to tissue and a controller configured to measure time of energy delivery to tissue and to calculate energy delivered to tissue, the controller further configured to estimate a size of an ablation volume as a function of energy delivered to tissue and time and to calculate a growth rate of the ablation volume based on the estimated size.
