AbstractA novel hydrodynamic blood pump with a very clean flow path free of outflow stator blades which have been found to be a site of blood clot formation is introduced. The invention combines an axial flow pump impeller with a bladeless volute structure typical of centrifugal pumps to obtain a miniaturized hybrid blood pump configured to be surgically implanted such that the axial flow pump impeller is located within the heart and the spiral volute portion of the device is located outside the heart.
