摘要： A system and method for diagnosis or treatment of tissue is provided. One or more optic fibers are disposed within a deformable, tubular body. An electronic control unit activates an electromagnetic radiation source to direct a first set of electromagnetic radiation through a first optic fiber to the tissue. The unit also receives a signal generated by an electromagnetic radiation sensor in response to a second set of electromagnetic radiation received through the first optic or a second fiber. The second set of electromagnetic radiation originates from the tissue in response to the first set of electromagnetic radiation and may be reflected or emitted by a substance contained in the tissue that alters radiation characteristics of the tissue. Finally, the unit is configured to determine a characteristic of the tissue (e.g. the distance from the tissue to the tubular body) responsive to the signal.

摘要： An ablation catheter (10) is provided for ablating internal tissue of a patient. The catheter includes a distal end that is adapted to be inserted into a body cavity relative to a desired location therein (e.g., within the heart). An ablation electrode (22) is connected relative to the distal end of the catheter (10) for providing ablation energy to patient tissue. A heat sink (40) is provided that is in thermal contact with the ablation electrode (22). The heat sink (40), in addition to being in thermal contact with the ablation electrode (22), is electrically isolated from the ablation electrode (22). This allows the heat sink (40) to conduct heat away from the ablation electrode (22) without dissipating electrical energy from the electrode (22). In this regard, the heat sink (40) may prevent build-up of excess heat within the electrode (22) that may result in blood coagulation and/or tissue charring.
