Abstract

<p>We have been developed a pulmonary circulatory assist device for pediatric patients to promote hemodynamics of Fontan circulation. In this study, in order to develop the cooling system for a pulmonary circulatory assist device by heat pipes, we examined heat transfer response of the device, and we also designed basically heat transfer system by using heat pipes. In the animal experimental model, hot spot of during device contraction was around 45 degree Celsius in the rigid support sheath area. Whereas, there were no thermal elevation in extra cardiac conduit. From the temperature difference between the maximum device temperature and the blood temperature, we considered to be selecting the sealed gas and the filling pressure for heat pipe design. In the future prospects, we are due to develop prototype cooling system by waste heat to the blood vessel with heat pipe.</p>
