With the current development of the medical engineering technique, various ventricular assist devices have been developed and clinically applied, and several numbers of patients have socially recovered. However, the compactness, the lightness, the high-power and the durability will be the key for future advanced medicine since the ventricular assist device with higher performance and more safety is still desired. Now, it is necessary to reorganize the medical engineering techniques about ventricular assist device. With the reorganization, the individual characteristics of the ventricular assist devices and cardiopulmonary bypass pumps will be revealed which has been developed in the past, the present, or the future, that promotes the development of the research and clinical field including many medical devices. In this overview, we focused the geometry of the blood pump, and compared about the pump performance, the hemo-compatibility, the performance for the clinical use to reorganize the medical actuation technique.
