US Patent No: 5853409

Systems and apparatus for sensing temperature in body tissue

---

Abstract

---

An apparatus for ablating body tissue has an electrode for contacting tissue to transmit ablation energy. A tissue temperature sensing element is held in a thermally conducting carrier on the electrode. The carrier holds the tissue temperature sensing element in thermal conductive contact with tissue, while keeping the temperature sensing element in isolation from thermal conductive contact with the electrode. The carrier has prescribed thermal conductive characteristics that significantly improve the sensitivity of the temperature sensing element to tissue temperature and not the temperature of the electrode.
