Abstract
For heat ablating living tissue of a body, an ablation electrode, contacting a surface of the tissue or within tissue, is coupled to an RF power supply referenced to a second electrode contacting the body. Fluid coolant is circulated to cool the contact surface extending the ablation to an increased volume of tissue. Temperature may be sensed contiguous to the surface to control the flows of RF heating energy and fluid coolant. Computer capability implements control and provides graphics of data, preplans, or controls relative to the ablation. Several forms of electrode structures accommodate specific objectives.
