Abstract
The invention provides an axial flow blood pump with slanting outflow components. Specifically, the invention provides a blood pump having an angling outer stator blade edge structure in combination with a blood flow conduit having a constricting inner diameter. After constricting, the blood flow conduit can expand such that the inner diameter of the conduit increases. In addition, the blood pump can have an angling inner stator blade edge structure and a tapering stator blade hub or tapering rotor element.
