The research and development of Left Ventricular Assist Device (LVAD) is hoped as a cure for seriously ill heart patient We developed an enclosed-impeller axial flow blood pump for a LVAD. However, this pump has serious problems of hemolysis. The factor of main hemolysis is surface characteristic of the vane which is a blood contact surface. Therefore, we paid attention to a hydrcgenated amorphous carbon (a-C:H) film. Recently, a-C:H film is expected as biomateriaL The purpose of this study, the hemolysis performance is improved by a-C:H film. a-C:H film was deposited a radio-frequency plasma Chemical Vapor Deposition (CVD) technique. The hemolysis was compared using the coating vane and pure vane. As a result of hemolytic examination, a-C:H film coating reduce the hemolysis performance. From this thing, a-C:H film coating reduce the hemolysis performance.
