We have developed and improved a transcutaneous electromagnetic bi-directional data transmission system for an artificial heart. In this system, ASK (Amplitude Shift Keying) modulation with carrier frequencies of 4 MHz and 10 MHz is employed in consideration of electromagnetic permittivity into tissue, and which involves less interference for bi-directional transmission. To miniaturize each TDT unit size, the TDT system consists primarily of a one·chip microcomputer with circuit boards designed by CAD and CAM technology. The model for molding the electronics circuit is designed by CAD, and manufactured by CAM and a 3-axial NC machine. The size of each unit is 45 mm in diameter and 8 mm in thickness. In vitro experimental results showed that the TDT system could transmit data, via a transcutaneous energy transmission system, a within an area of axial direction of 7.5 cm and a radial direction of 4 cm without interference. The results of animal experiments in which the TDT system was implanted inside a goat showed excellent fitting and stable operation during a period of 87 days. This demonstrates the convenience of the TDT system for transcutaneous bi-directional communication in an implantable artificial heart system.
