Abstract

Disclosed is a blood pump rotor, and an intravascular blood pump that utilizes the rotor. The blood pump rotor is configured to rotate around an axis of rotation, and comprises a distal portion and a proximal portion. The distal portion includes a rotor hub, which tapers in a distal direction. The rotor hub has at least one blade extending outward from the rotor hub. Further, a distal end of said rotor hub extends distally beyond a most distal portion of the at least one blade. The proximal portion, which is connected to the distal portion, has permanent magnets arranged so as to form a Halbach array generating a magnetic field having a magnetic flux in a proximal direction that is greater than a magnetic flux in a distal direction, said first magnetic flux being greater than said second magnetic flux. The Halbach array comprises an alternating arrangement of axial magnetized magnets and circumferential magnetized magnets. At least one secondary blade is provided on a proximal surface of at least one circumferential magnetized magnet, wherein the at least one secondary blade extends axially in a proximal direction.
