Abstract: A radio-frequency ablation system is disclosed in which the power, voltage, or temperature delivered to multiple electrodes may be dynamically controlled, and in which the electrodes may be simultaneously energized in phase with each other to achieve a desired lesion pattern. The system comprises a multiple electrode ablation catheter, each electrode having a temperature sensor operatively associated therewith. Each electrode is energized by its own RF amplifier, and all of the electrodes are driven in phase with each other by a common sine wave oscillator. A feedback network controls the degree of amplification of the separate RF amplifiers. According to a further aspect of the invention, a modular power supply arrangement is disclosed which is configurable to dynamically control the power, voltage, or temperature delivered to multiple electrodes of a multipolar ablation device. An arbitrary number of electrodes may be simultaneously energized in phase with each other to achieve a desired lesion pattern using the modular power supply by providing a sufficient number of removable modules.

Abstract translation: 公开了一种射频消融系统，其中可以动态地控制输送到多个电极的功率，电压或温度，并且其中电极可以同时相位通电以实现期望的损伤模式。 该系统包括多电极消融导管，每个电极具有与其可操作地相关联的温度传感器。 每个电极由其自己的RF放大器激励，并且所有电极通过公共正弦波振荡器彼此相位驱动。 反馈网络控制单独RF放大器的放大程度。 根据本发明的另一方面，公开了一种模块化电源装置，其可配置为动态地控制传送到多极消融装置的多个电极的功率，电压或温度。 任意数量的电极可以同时相位通电，以通过提供足够数量的可移除模块来使用模块化电源实现期望的损伤模式。
