Recently, the majority of artificial hearts have been non-pulsatile types. However natural hearts are pulsatile, and the long-term bio-compatibility of the non-pulsatile types has not been confirmed. We developed a linear actuator that can expect to be applied to pulsatile artificial heart. This linear actuator was applied to an electromagnetic pump. It consists of power transmission, tanks, and permanent magnets. We propose a structure to reduce power consumption by a spring. Reduction in power consumption makes possible to downsize the entire apparatus.
