An ablation catheter system, includes a guiding/mapping catheter assembly (10) and a laser catheter (50). The guiding/mapping catheter includes ring electrodes (22), tip electrodes (18, 20), a movable fixation wire (24), and a central catheter lumen (17) for an ablation catheter. A laser catheter includes an optical fiber (66) for passing laser energy, tip electrodes (76, 78), an optical fiber port, and thermocouples (72, 74) on the end of hypodermic tubing. The laser catheter electrodes are used to monitor the progress of the tissue ablation or disruption process, and to help minimise damage to healthy tissue. |
