Abstract

The invention relates to a blood pump. The blood pump comprises a flexible drive shaft () guided in a catheter, a conveying element () connected to the drive shaft () in a distal region of the drive shaft (), and a motor (), wherein the motor () has a stator () and a rotor () mounted such that it can move in the stator (). The stator () comprises a winding () and the rotor () comprises a rotor magnet (). In addition, the drive shaft () is connected to the rotor () at a proximal end of the drive shaft (). The stator () and the rotor () are nondetachably connected to one another, and form a gap () with a ring-shaped cross-section, which is delimited by the rotor () and the stator ().
