The design requirements of the blood pump for implantable ventricular devices and total artificial heart are heavily affected by the anatomical limitation such as the intrathoracic space capacity and blood vessel layout. It is also necessary to modify the design of blood pumps for built-in use in the case of integrated pump lung system. Limitation occurs at the blood inflow position to the oxygenator whether the configuration of oxygenator was cylindrical or box shape. The design and structure of outflow port in the blood pump was decided according to the smoothness of the blood flow. Our research group tried to design the blood pumps specialized for built-in apparatus. In this study, we report a newly designed the multi-stage centrifugal pump named Sequential Flow Pump that two steps of pressurization is possible with one impeller.
