The application relates to an external drive unit () for an implantable heart assist pump. The proposed drive unit () comprises a motor () for driving the heart assist pump, wherein the motor () is connectable to the heart assist pump via a transcutaneous drive shaft (). The drive unit () further comprises a heat spreader () comprising a contact surface configured to contact and/or directly contact and/or lie flat against a skin of a patient. The contact surface is connected or connectable with the motor () in a thermally-conductive manner to transfer heat generated by the motor () to tissue of the patient.

External drive unit for an implantable heart assist pump

A blood pump rotor for an intravascular blood pump includes a distal portion having a rotor hub. A distal end of the rotor hub extends beyond a most distal portion of at least one blade formed on the hub. A proximal portion comprises permanent magnets arranged to form a modified Halbach array generating a magnetic field with a first magnetic flux in a proximal direction that is greater than a second magnetic flux in the distal direction. The array is arranged so that: (a) at least one axial magnetized magnet has a most proximal point that is a different distance from said distal end as compared to a most proximal point of at least one circumferential magnetized magnet, (b) at least one axial magnetized magnet has a physical dimension that is different from a corresponding physical dimension of at least one circumferential magnetized magnet, or (c) a combination thereof.
