Title:
複数の温度感知要素を使用して組織のアブレーションを制御するためのシステム
Document Type and Number:
Japanese Patent JP3564141
Kind Code:
B2
Abstract:
A system and associated method ablate body tissue using multiple emitters of ablating energy. The system and method convey ablating energy individually to each emitter in a sequence of power pulses. The system and method periodically sense temperature at each emitter and compare the sensed temperatures to a desired temperature established for all emitters to generate a signal individually for each emitter based upon the comparison. The system and method individually vary the power pulse to each emitter based upon the signal for that emitter to maintain the temperatures at all emitters essentially at the desired temperature during tissue ablation.
