| 摘要 |
The present invention relates to a radio-frequency ablation system for biological tissues. The ablation system comprises an electrode catheter (200) having an array of externally conductive, individually connected electrodes (202, 204) arranged in spaced serial relation along a shaft, a plurality of temperature sensors (208), each thermally associated with a different electrode in said array for providing a temperature signal representative of the temperature of that electrode, a power supply arrangement (100) adapted to maintain constant power, voltage or temperature at each electrode of said array, and means (112) operatively attached to and in signal communication with said power supply arrangement, said means being programmed to provide control signals to said power supply arrangement for individually controlling each electrode of said array, and for switching said array of electrodes between constant power, voltage or temperature mode. <IMAGE>
