Design Parameters of Heart Pump

In this paper, design parameters of new bladeless centrifugal heart pump are presented. The application of pump as heart pump imposes design limitations on the geometry of the heart pump. Research and development of heart pump is focused on achieving heart pump performance and hemocompatibility i.e., the amount of mechanical damage caused by a pump on blood cells. Main prediction parameter of pump hemocompatibility is wall shear stress, stagnation, and recirculation zones. The bladeless centrifugal heart pump creates less shear stress, as the flow is created due to adhesive and cohesive forces, without impact of blood cells on rigid blade surfaces resulting in greater hemocompatibility.
