<p>A centrifugal pump (10) for pumping biological fluids such as blood includes a housing which defines a pumping chamber. The pumping chamber encloses an impeller (16) comprised of a spindle (42) for rotation about a spindle axis and a plurality of blades (46) positioned such that each inner blade end is positioned adjacent to the spindle (42). The plurality of inner blade ends forms a spin inducer (52) which aids in decreasing hemolysis.</p> |
