POLYMER VALVE CAPABLE OF PASSING MORE BLOOD PER UNIT TIME AND A PULSATILE CONDUIT-TYPE VENTRICULAR ASSIST DEVICE USING THE SAME

摘要

PURPOSE: A polymer valve and a pulsatile conduit-type ventricular assist device using the same are provided to secure long time use thereof by decentralizing the power that is repetitively and continuously applied to a leaflet.;CONSTITUTION: A polymer valve comprises: a supporting member(11) equipped with a pair of support stands(12) which are expanded in a first direction so that a pair of cut surfaces can be formed in both sides thereof; and a pair of leaflets(14) of a film shape which are made of a polymer material and are covered on each cut surface. In the leaflet, a hole is formed. The leaflet moves between an opened position and a closed position.;COPYRIGHT KIPO 2012
