The present invention pertains to a blood pump device which comprises a blood pump having blood transport ports and cannulae connected to the ports. The blood pump device also comprises a coating material covering the junction between the inner surfaces of the ports and cannulae. This forms a smooth transition so blood can flow unimpeded therefrom and collection cavities for the blood are eliminated. The invention is also related to a method of producing a smooth coating. The present invention is a blood pump device comprising a second portion having a stator mechanism and a rotor mechanism disposed adjacent to and driven by the stator mechanism. The second portion has a journal disposed about the rotor mechanism to provide support therewith. The second portion has an impeller disposed in the chamber and a one-piece seal member for sealing about a shaft of the impeller. The seal member is fixedly attached to the journal so that the seal member is supported by the journal. The present invention is also related to means for providing power to the blood pump so that blood can be pumped through a cannulae. The providing means includes a controller having means for sensing pump failure …
