A Miniature TES powered Stirling-cycle engine
Abstract
Miniature Stirling-cycle engines are under development for use in powering implantable ventricular assist devices. Approaches which have been employed to drive these devices rely on the generation of either hydraulic or pneumatic power. This generated power is converted by hydraulic or pneumatic logic control to mechanical power which, in turn, actuates pusher-plate blood pumps. The logic control enables the blood pump to be cycled synchronously (counter-pulsatile mode) with the heart. Because Stirling-cycle engines are heated externally, a variety of energy sources can be used. Restrictions for this application are for the energy source to be small and self contained while suppling heat in the range of 500 to 850/sup 0/C. Historically these systems were designed to be powered by a radioisotope. More recently, thermal energy system utilizing the latent heat of fusion of fluoride eutectic salts are being developed to power the engine for 8 hours of tether free operation.
