- A new version of a moving actuator electromechanical total artificial heart was
designed to improve the total efficiency, durability, and fit inside the thoracic cavity.
Compared with our present type of rolling-cylinder actuator, this new model has a pendulum-
type actuator with reciprocating motion around a fixed circular path connected through
the gear mechanisms to the motor. By using this mechanism, efficiency and "durability improved
by replacing the sliding mechanism with rolling contact elements. Also, the height of
the pump decreased from 9 cm to 7 cm with a static stroke volume of 65 cc.
With this new pump, we performed two animal experiments. We also evaluated the
engineering feasibility of implanting this pump into a small, human-size animal (less than 70
