Abstract
A magnetically driven, axial flow pump comprises an electromagnetic unit arranged about the periphery of a pipe. A cylindrical rotor is accommodated within the pipe and is equipped with permanent magnets mounted on the periphery. A spiral, hollow vane is formed on an inner surface of the rotor by either casting or by cutting, such as with a NC machine, thus precluding the occurrence of gaps between the rotor and the vane. The lack of gaps within the pump makes the pump suitable for use as a blood pump.
