Abstract
This paper deals with basic characteristics by mock test of a linear pulse motor-driven artificial heart. The artificial heart consists mainly of a linear pulse motor and a blood pump mechanically coupled to each other. The linear pulse motor has a flat structure made with laminated sheets of permendure and rare-earth magnets. Two kinds of blood pumps, the diaphragm and pusher cup type, were prepared for the mock test. In the diaphragm type, aortic pressure of 69 to 103 mmHg can be obtained in the case of 113 bpm (beats per min). In the pusher cup type, the aortic pressure of 53 to 97 mmHg was obtained at 130 bpm. The artificial heart was thus confirmed to have implantation potential.
