Systems and methods for sensing sub-surface temperatures in body tissue
 Systems and methods supply ablation energy to an electrode in contact with tissue to form a tissue-electrode interface. The system and methods sense, simultaneously with ablation, at least two tissue temperature conditions using at least two tissue temperature sensing elements which are held within a carrier that is substantially isolated from thermal conductive contact with the electrode. The carrier holds the tissue temperature sensing elements in a spaced apart relationship in thermal conductive contact with tissue at different depths beneath the tissue-electrode interface. The systems and methods control the supply of ablation energy to the electrode based, at least in part, upon temperatures sensed by the tissue temperature sensing elements.
