The system of Transcutaneous Energy and Information Transmission for a Totally-Implantable Artificial Heart

-Reduction of Magnetic Field Effects by Cutting the Outer Circumference of Two Turns of the Outer Circumference of Figure-eight Coil-

Abstract

　For a totally-implantable artificial Heart (TIAH), the transcutaneous energy transmission system (TETS) and the transcutaneous communication system (TCS) are useful to reduce the risk of infection. Integration of TETS and TCS is expected to reduce patient’s burden, including miniaturizing the device. We have studied the two turns of the outer circumference of figure-eight coil for the integration of transdermal energy transmission and transdermal information transmission. In this study, a part of the two turns of the outer circumference of figure-eight coil is cut off to further reduce the effect of the magnetic field on information transmission by energy transmission. In addition, the magnetic field effects caused by the misalignment of the transdermal transformer are compared before and after cutting the circumstance of the coil in the information transmission system.
