| Outline of Final Research Achievements |
Generally, the artificial heart refers to the left ventricular assist device, designed to assist the left ventricle. In this study, however, we worked on the development of an artificial heart that can support or replace both ventricular with a single rotor. In this research, we mainly researched and developed a magnetic levitation pump. We clarified that the manufactured magnetic levitation pump achieved a pumping capacity of 100 mmHg and a flow rate of 5.8 L/min at a nominal rotation speed of 1800 r/min. We clarified the pump could support both ventricles.

| Academic Significance and Societal Importance of the Research Achievements |
一般的な人工心臓は左心室の補助を目的としている。しかし，左心室と右心室の両心が不全な患者も少なくない，そこで本研究では左心室と右心室の両方を1つの人工心臓で補助または置換することを目的とした。ポンプ特性試験を行い，製作した磁気浮上ポンプが両心室を補助可能な性能を有することを明らかにした。また，高性能な人工心臓開発への取り組みは，重症心不全患者の生活の質の向上に直結するため，社会的意義も高い。
