We have developed a non-contacting type centrifugal blood pump with hydrodynamic bearings. The purpose of this study is development and Hemocompatibility evaluation of the assisted circulation pump with hydrodynamic bearings. By the test, we evaluated the different closed impeller of the shrouds inside diameter. As a result, the bearing gap of the top and bottom became a large gap more than 100μm. At 4L/min and 200mmHg differential pressure, the hemolysis index was equal with a commercial pump.
