SINKHOLE BILEAFLET POLYMER HEART VALVE

摘要

The sinkhole bileafle polymer heart valve having a blood compatibility and durability, is useful for an artificial heart valve for a blood pump, a total artificial heart valve for substitution and a heart valve of a ventricular assist device. A heart valve frame is prepared by impregnating isoplast having a width of 1 mm and a space of 3 mm into pellethane solution. The pellethane solution in dimethylacetamide is molded a thickness of 0.2 mm on the glass plate, and punched to a round shape to give a leaflet.
