N2 - The total artificial heart (TAH) has been expected to solve some problems of heart transplant. We have been developing the TAH using helical flow pump (HFP). The HFP has a hydrodynamic bearing and can eject pulsatile flow. To date, satisfactory pump was developed for the left pump, however for the right pump, there remains the problem in the hydrodynamic bearing. The purpose of this study was to investigate the right pump in order that hydrodynamic bearing functions well in pulmonary circulation and to achieve an improvement in the right pump. Based on the investigation, among various parameters of the pump structure, the vane of the impeller was decided to be smaller. The performance of the improved right pump showed that the pump could work in wider range than the original pump, which was more suitable for pulmonary circulation. In animal experiment, the improved right pump worked in a stable condition. However, the problem of accuracy in dimension of the bearings was found, which should be improved rapidly.
