Abstract
An electrosurgical technique of achieving coagulation involves conducting a predetermined ionizable gas in a jet to the tissue at a predetermined flow rate sufficient to clear natural fluids from the tissue and to substantially expose the tissue stroma. Electrical radio frequency energy is conducted to the tissue in ionized conductive pathways in the gas jet. To achieve fulguration, the electrical energy is conducted as arcs in the ionized conductive pathways. To achieve a non-contact type of electrosurgical desiccation, the electrical energy is conducted as a non-arcing diffuse current in the ionized conductive pathways.
