Abstract

An electro-hydraulic total artificial heart system consisted of a separately placed actuator and blood pumps was designed. In the actuator a brushless DC motor is sandwiched by 2 pusher-plate pumps connected with the blood pumps by flexible tubes. A roller-screw system is employed for alternative pumping and silicone oil is used to trans-mit the action. The pumps were implanted in 4 goats of 54-59 kg as a pneumatic sys-tem. The longest survivor could be maintained for 40 days. The system could yield around 6L/min in an in vitro evaluation.
