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 comprised of a spindle for rotation about a spindle axis and a plurality of blades positioned such that each inner blade end is positioned adjacent to the spindle. The plurality of inner blade ends forms a spin inducer which aids in decreasing hemolysis.
