Abstract
An intravascular blood pump designed to be advanced through the blood vessel system of the patient, comprises a housing () accommodating an electric motor (), the proximal end of the housing () being connected to a catheter () and the distal end thereof carrying a pump (). The electric motor () includes a stator winding () forming a load-bearing component of the housing (). The stator winding () is embedded in a matrix made of synthetic resin. The housing () 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.
