A blood pump comprises a pump casing having a blood flow inlet and a blood flow outlet, and an impeller arranged in said pump casing and rotatably supported in the pump casing by a bearing so as to be rotatable about an axis of rotation. The impeller has blades for conveying blood from the blood flow inlet to the blood flow outlet. The bearing comprises at least one stationary bearing portion coupled to the pump casing and having a stationary bearing surface that faces radially outwards. The bearing further comprises a rotating bearing surface interacting with the stationary bearing surface to form the bearing, wherein the rotating bearing surface faces radially inwards and is formed on an exposed radially inner edge of the blades. The blades are designed to draw blood deposit on the stationary bearing surface in a radially outward direction.

Blood pump

An intravascular blood pump () comprises a pump casing () having a blood flow inlet () and a blood flow outlet (), and an impeller () arranged in said pump casing () so as to be rotatable about an axis of rotation, wherein the impeller () has blades () sized and shaped for conveying blood from the blood flow inlet () to the blood flow outlet (). The blood pump () further comprises a drive unit () for rotating the impeller (), the drive unit () comprising a plurality of posts () arranged about the axis of rotation (). Coil windings () around the posts are sequentially controllable so as to create a rotating magnetic field. The shaft portion () of each of the posts () comprises a soft magnetic material which is discontinuous in cross-section transverse to the longitudinal axis of the respective post ().
