A hydrodynamic levitation centrifugal pump is being developed for a long-term implantable artificial heart. The hemocompatibility was investigated with numerical analysis and has been verified with animal blood tests. The hemolytic property was improved by expanding the bearing gap and by adjusting the pressure balance and the antithrombogenicity has been improved by adding deep grooves to the hydrodynamic bearings to increase the flow rate through the bearings.
