| Outline of Final Research Achievements |
In order to develop an implantable ventricular assist device that has high durability for a small adult patient, studies on mechanical characteristics and miniaturization of the magnetically levitated ventricular assist device were performed. To estimate magnetic attractive forces acting on the rotor-impeller, the estimate equation of magnetic suspension force in the radial direction, the estimate equation of negative spring force in the radial direction and the estimate equation of the restoring force in the axial direction were derived. The pump performance and the fluid force acting on the rotor-impeller using a computational fluid dynamics were estimated, and a centrifugal pump was designed. The small self-bearing motor and the small magnetically levitated centrifugal blood pump were developed, and basic performances of these were evaluated.
