Abstract
An intravascular blood pump designed to be advanced through the blood vessel system of the patient, comprises a housing (15) accommodating an electric motor (12), the proximal end of the housing (15) being connected to a catheter (23) and the distal end thereof carrying a pump (11). The electric motor (12) includes a stator winding (17) forming a load-bearing component of the housing (15). The stator winding (17) is embedded in a matrix made of synthetic resin. The housing (15) is of an ironless design without any magnetic reflux device. The motor is operated with a rotational speed of about 50,000 upm. The magnetic stray field generated with such high frequencies does not disturb the cardiac rhythm of the patient. The motor can be given a compact size and thus has a high mechanical output power.
