FLOW VISUALIZATION ANALYSIS OF THE VIBRATING ELECTROMAGNETIC DRIVEN ARTFICIAL HEART-ESPECIALLY ON THE FLOW SURROUNDING THE JELLYFISH VALVE-A

Abstract

A vibrating electromagnetical ly driven artificial heart which had an unique structure and pumping mecha-nism, was developed in our team. In order to analyze the blood flow patterns inside the pump incorporated with the Jellyfish valve, flow visualization study was performed by the tracer-methods. When Jellyfish valve opend, inflow to the valve chamber constitute to cause the large swirl, which washed out the blood in the central point of the Jellyfish valve. These results ofthis study indicate that the vibrating electromagnetically driven artificial heart with jellyfish valve has the thrombo resistant properties which is very im-portant facter in the clinical use of tortal artificial heart.
