| Outline of Final Research Achievements |
In an acute animal experiment, the total artificial circulation model was made using the centrifugal type after marketing ,left ventricular assist devices, the regular way, an achieved possibility of the centrifugal type blood pump total artificial heart was indicated. An atrium pulse was kept in the total artificial heart animal experiment model, and we found that physiological control by automatic nerves system control might be achieved. A concept model of the total artificial heart was made using a three-dimensional printer and fitting study was performed in adult goats of sacrifice after the other experiments. The independent left and right blood pumps type total artificial heart concept of was indicated by miniaturizing the blood pumps. It was low in cost and a small embroidered design in one constraint ball bearing aiming longer durability was contrived and the movement was confirmed in a prototype pump.
