Abstract

본 발명은 반 열린 스텐트유닛과 이를 포함하는 자유 각도 풍선도자유닛에 관한 것으로, 더욱 상세하게는 주혈관과 분지혈관에 혈전으로 인해 주혈관과 분지혈관이 협착 되는 경우 주혈관과 분지혈관을 동시에 확장하기 위하여 반 열린 스텐트유닛을 장착하고 분지혈관의 다양한 각도에 순응하는 자유각도 풍선도자유닛을 주혈관과 분지혈관 내로 삽입하고, 상기 자유각도 풍선도자유닛을 팽창시키면 이에 대응하여 확장되고, 상호 간섭하지 않는 반 열린 스텐트를 주혈관과 분지혈관에 장착시켜 혈관을 확장시키는 반 열린 스텐트유닛과 이를 포함하는 자유 각도 풍선도자유닛에 관한 것이다. 상기와 같은 본 발명에 따르면, 주혈관용 반 열린 스텐트와 분지혈관용 반 열린 스텐트를 동시에 각각 주혈관과 분지혈관에 삽입시키고 상기 혈관들을 동시에 확장할 수 있고, 반 열린 스텐트의 열린 형상은 주혈관용 반 열린 스텐트와 분지혈관용 반 열린 스텐트가 상호 간섭되는 것을 방지하고, 상기 반 열린 스텐트를 장착하는 자유각도 풍선도자유닛은 풍선 각도가 다양하게 제어되어 인체에 내강하는 주혈관과 분지혈관의 여러 각도에 순응되고, 반 열린 스텐트가 혈관에 정확하게 장착되는 효과가 있다.
