  • Centrifugal blood pump
    Patent number: 5360317
    Abstract: A centrifugal pump for pumping biological fluids such as blood includes a housing which defines a pumping chamber. The pumping chamber encloses an impeller mounted on a spindle. The impeller carries coupling mechanisms which couple with an external source of rotation to rotate the impeller. The spindle allows the impeller to rotate freely, but both ends of the spindle are constrained in the axial and lateral directions. The housing includes an inlet and an outlet.
