    We have been developing several variations of circulatory assist systems based on nano or micro engineering technologies. One of the special features of the design of these new styles of circulatory assist devices will be a passive controllability according to the native physiological signal transmission and hemodynamic responses. In this study, we presented the design features and the research diversity for the development of passive-active circulatory support systems, such as artificial myocardial assist devices, circulatory valves, epi-cardial or vascular support systems for mechanical assistance in chronic or congenital heart failure patients. We employed a covalent type shape memory alloy fiber as the actuator for the implantable artificial internal organs for sophisticated ventricular or hemodynamic support devices.
