摘要： A centrifugal blood pump assembly according to one aspect of the invention includes a housing, an impeller adapted to rotate within the housing for feeding blood, an impeller position control device, and an impeller rotation torque generating device. The impeller rotates without contacting the inner surface of the housing when the position control device and torque generating device are operative. Even when the position control device is inoperative, operation of the torque generating device enables rotation of the impeller while a blood flowpath is defined between the surface of the impeller facing the torque generating device and the inner surface of the housing. A centrifugal blood pump assembly according to another aspect of the invention involves a pump including a housing having blood inlet and outlet ports and an impeller adapted to rotate within the housing for feeding blood. The assembly also includes an uncontrolled magnetic bearing arrangement for the impeller, and controlled magnetic bearing arrangement for the impeller. The bearing arrangements are removably mounted to the pump.

摘要： A hydrodynamic type bearing unit with enhanced moment load capacity. In the bearing unit, a radial bearing clearance and thrust bearing clearances are set at such widths that a tilted spindle member comes into contact at the outer periphery of its spindle with both axial ends of a radial bearing surface opposed thereto, as well as at the rims of both end faces of its flange portion with respective thrust bearing surfaces opposed thereto, so that the moment load can by supported by both the radial bearing part and the thrust bearing part. Specifically, the radial bearing clearance &dgr;R and the thrust bearing clearances &dgr;A are set in accordance with the expression D&dgr;R/L+&egr;≧&dgr;A≧D&dgr;R/L (where D is the diameter of the flange portion, L is the axial length of the radial bearing part, and &egr; is a machining error).
