Animal experiments using a total artificial heart in a goat are not easy to perform. The fourth model of the undulation pump total artificial heart (UPTAH4), which was designed to perform a long‐term physiological experiment including pulsatile and nonpulsatile TAH operations with a conductance‐ and arterial pressure‐based control method named 1/R control, was implanted in 31 goats weighing 38.5 to...
Severe cardiac failure patients require a total artificial heart (TAH) to save life. To realize a TAH that can fit a body of small stature and has high performance, high durability, good anatomical fitting, good blood compatibility, and physiological control, we have been developing the helical flow TAH (HFTAH) with two helical flow pumps with hydrodynamic levitation impeller. Animal experiments of...
