A method and apparatus for transmural ablation using an instrument containing two electrodes or cryogenic probes. A clamping force is exerted on the two electrodes or probes such that the tissue of the hollow organ is clamped therebetween. Bipolar RF energy is then applied between the two electrodes,...http://www.google.com/patents/US6974454?utm_source=gb-gplus-sharePatent US6974454 - Transmural ablation device with thermocouple for measuring tissue temperature
