Abstract

본 발명은 교류 전류 AC를 이용하여 포유동물에서 혈관과 같은 관강을 폐색하고 또한 혈관 협착 및/또는 전기응혈을 측정하기 위하여 폐색 부위로부터 반사 전류를 모니터하기 위한 장치를 제공하는 것을 목적으로 한다. 본 발명에 따르면, 교류 전류(AC) 전력 발생기와, 상기 발생기에 전기적으로 접속된 제1전극(바람직하게는 폐색 삽입물)과, 상기 발생기엔 전기적으로 접속되며 상기 발생기와 제1전극과 함께 구동회로를 형성하는 분산 전극과, 그리고 상기 제1전극으로부터 발생기로 반사되는 전력을 모니터하기 위하여 상기 구동회로에 접속된 반사전력 모니터 회로를 포함한다. 이러한 구조에 의하면, 폐색 및 /또는 열적응혈이 정밀하게 검출되어, 포유동물에 위치할 때 제1전극으로 전달되는 전력이 차단된다. 이에 의하면 협착된 혈관에 인접한 조직을 과열시키는 위험이 최소화 또는 제거된다.
