Abstract

폴리머 밸브와 이를 이용한 심실보조장치가 개시된다. 본 발명에 따른 폴리머 밸브는, 혈액이 제1 방향으로는 유동할 수 있되, 상기 제1 방향과 반대 방향인 제2 방향으로의 역류는 방지하는 폴리머 밸브로서, 혈액이 통과하는 양단으로 개방된 중공을 가지고, 양측으로 한 쌍의 절개면이 형성되도록 상기 제1 방향으로 연장되어 형성된 한 쌍의 지지대를 구비하는 지지 부재; 및 폴리머 재질로 이루어지며, 상기 각 절개면 상에 씌워지는 막 형상의 한 쌍의 리플렛; 을 포함하여 구성되며, 상기 한 쌍의 리플렛은 연결부에 의해 단부에서 연결되며, 상기 리플렛에는 구멍이 형성되고, 상기 리플렛은 혈액이 상기 제1 방향으로 유동할 때 상기 구멍이 개방되도록 서로 떨어지는 개방 위치와, 혈액이 상기 제2 방향으로 유동하려 할 때 상기 구멍이 폐쇄되도록 상기 구멍 부근에서 서로 밀착하는 폐쇄 위치 사이에서 움직임이 가능한 것을 특징으로 한다.
