Abstract
【解決手段】マイクロ波焼灼システムは、エネルギーを出力するように動作可能な発生器と、発生器に接続され、エネルギーを組織領域に送達する焼灼プローブとを備える。焼灼システムはまた、発生器を制御するように動作可能な制御器と、焼灼プローブおよび制御器に接続され、焼灼プローブの動作パラメータを検出する少なくとも1つのセンサとを備える。制御器は、発生器のエネルギー出力を低エネルギーレベルから高エネルギーレベルにランプアップさせることによってシステムチェックを行い、システムチェック時にセンサからの出力を所定の時間間隔で監視して、異常状態を判断する。制御器が異常状態と判断した場合には、制御器が発生器を制御してエネルギー出力を停止する。
