Abstract
This invention concerns an intravascular blood pump for percutaneous insertion into a patient's blood vessel comprising 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. The impeller has blades designed for conveying blood from the inlet and outlet. The blood pump comprises a drive unit with a plurality of posts about an axis for rotating the impeller. Each of the posts has a longitudinal axis and an impeller-side end pointing towards the impeller. A coil winding is disposed around each of the posts and has an impeller-side end pointing towards the impeller. The coil windings are controllable to create a rotating magnetic field, wherein the impeller comprises a magnetic structure arranged to interact with the rotating magnetic field to cause rotation of the impeller.
