Key Points

To establish a theoretical model that predicts mechanical blood trauma and hemolysis in artificial circulatory devices by combining mechanical loading dynamics with a damage accumulation hypothesis.
Extracted arbitrary stress-time histories of blood particles using three-dimensional numerical flow simulations of an Aries Medical Isoflow centrifugal pump.
Decomposed complex transient stress profiles into simplified harmonic loading components classified into damaging and nondamaging regimes.
Applied a damage accumulation hypothesis to sum cumulative mechanical trauma across blood particles traversing the pump domain.
Demonstrated a qualitative framework for mapping complex, irregular particle stress histories to hemolytic damage in rotary blood pumps.
Determined that accurate quantitative hemolysis forecasting requires further empirical characterization of blood cell tolerance under varying frequencies and amplitudes of transient harmonic stress.
