ANALYSIS OF EFFICIENCY AND EXPERIMENTAL CONSIDERATION OF ENERGY TRANSMISSION SYSTEM TO DRIVE TOTAL IMPLANTED ARTIFICIAL HEART

Abstract

The losses in the tissue when the electromagnetic energy at high frequency is transmitted to a driver of the TAH through intact skin using 2 coils are theoretically analyzed, and also, an expression of the relation between the efficiency and the several parameters of the system is derived from the electric circuit theory. We make experiments in vivo of an energy transmission system designed and manufactured by the above. As the results, the losses are very small in the tissue and are relatively large in the coils. The experiments also succeeded to drive both ventricles of the TAH in vitro and in vivo.
