development of mechanical circulatory support devices at the university of tokyo.the development of mechanical circulatory support devices at the university of tokyo has focused on developing a small total artificial heart (tah) since achieving 532 days of survival of an animal with a paracorporial pneumatically driven tah. the undulation pump was invented to meet this purpose. the undulation pump total artificial heart (uptah) is an implantable tah that uses an undulation pump. to date, the uptah has been implanted in 71 goats weighting from 39 to 72 kg. the control methods ...200717574507
present status of the total artificial heart at the university of tokyo.at the university of tokyo, various types of total artificial heart (tah) systems have been studied since 1959. at the present time, 2 types of implantable tah have been developed. one is an undulation pump tah (uptah) and the other is a flow transformed pulsatile tah (ftptah). using the uptah, 14 cases of implantation were performed in goats and 10 days' survival obtained. the new type of ftptah is under a prototype study. to prevent ring thrombus, a polyurethane membrane valve, a jellyfish val ...199910198712
