Abstract: A method and apparatus for inducing large volume heat ablations of tissue in a patient involving electrodes that are in contact with the patient's external surface or the surface of an internal organ. A high frequency signal or output from a generator is applied to the tissue near the area electrodes by connection of the generator to the electrodes. Various applications and configurations of electrodes and temperature monitoring are appropriate for different clinical needs and thermal distributions. The use for interoperative ablation of a tumor site within an internal organ or for ablation of a tumor from electrodes placed on the surface of the patient provides a clinical advantage.
