Abstract

<p>We have been developing the mock circulation system for a ventricular assist device. An artificial valves are important components for generating physiological load in such a system. In this study, we designed a trilobal-shaped valve intended for low pressure loss and high leaflet mobility. It was double structure with hard inner cylinder in order to suppress excessive deformation of the leaflets. Three types of valves with different the leaflets lengths were designed (S, M, L) and experimentally made with rubber like and hard resin using 3D modeling apparatus. These valves and conventional duckbill valve were mounted in the inlet and outlet of the pump of our mock system. The pressure across the outflow valve were measured in each valve. As a results, the pressure gradient of the produced valve was small compared with the duckbill. The index dP/dt of the after load showed the maximum value in the M type.</p>
