Systems and associated methods for ablating body tissue employ an electrode for contacting tissue to form a tissue-electrode interface. The electrode is adapted to be connected to a source of ablation energy to conduct ablation energy for transmission by the electrode into tissue at the tissue-electrode...http://www.google.se/patents/US6053912?utm_source=gb-gplus-sharePatent US6053912 - Systems and methods for sensing sub-surface temperatures in body tissue during ablation with actively cooled electrodes
