The development of core-type Transcutaneous Energy Transmission System for artificial heart

Recently, artificial heart (AH) is recognized as the alternate method of the heart graft. Though there are many problems and defect on AH, long term durability, miniaturization and weight saving interfaced with flow rate performance, efficiency of device. Considering rehabilitation into the society and advancement of QOL (quality of life), the construction of power source which supplies electric power to the device is important and has many problems. Especially, the electric feeder line restricts behavior of the transplant recipient and disturbs rehabilitation into the society. For solving these problems, transcutaneous energy transmission system (TETS) is noticed and studied. This study proposes core-type TETS. It achieves high magnetic coupling compared with air-core-type TETS which is carried out on clinical study. Because core-type TETS has high magnetic coupling, it is possible to reduce the input current and to miniaturize transformer size. This paper mentions the characteristic of core-type TETS
