          Heart failure is one of most severe diseases, and its cause of death is ranked higher all over the world. In order to assist cardiovascular support, we have developed a centrifugal blood pump as an artificial heart or extracorporeal circulation. The mechanism of centrifugal blood pump is basically the same as industrial pumps. However, the centrifugal blood pumps drive native blood as working fluid, therefore we have to think blood damage or blood coagulation by driving pumps. Under high shear flow in the pumps, red blood cells of the blood break due to shear stress, called hemolysis. Since the broken cell can not carry the oxygen molecules into the body, the patients will have an attack of anemia. On the other hand, under the low shear region, blood will coagulate due to the stagnation of the flow. Blood coagulation will cause infarction. From the reason written above, it is very important to introduce the fluid dynamic technologies, when a newly designed centrifugal blood pump are developed. In this talk, we will explain the pump design theory due to fluid dynamics and will show the results of in vetro testing, animal experiment and clinical use. Now we are developing newly advanced centrifugal blood pumps, thus impeller is sustained with hydrodynamic bearing for long time use.
