The principle of heart massager is applied to develop a new implantable cardiac supporting device that pushes the heart from outside to enhance the blood circulation only when it is needed. In order to use this devise clinically, this study aims to establish the methodology of the optimum design of its geometry and operating condition through numerical simulatioa As the first step, present report deals with development of the lumped parameter model of the systemic cycle of the cardiac system. Numerical solution was obtained with standard Runge-Kutta method. The solution qualitatively describes the dynamic characteristics of the system including essential information for the optimum design of the supporting devise, such as the power consumption and the energy of the cardiac motion. Furthermore, simulation was performed for a disabled heart to understand the effect of the parameter of the heart on the total blood flow.
