Abstract:
An intracardiac blood pump comprising a drive portion (11) with a motor (21), and a pump portion (12) rigidly connected with the drive portion, the drive portion and the pump portion having substantially the same diameter and being arranged coaxially with a mutual axial distance, and comprising a pressure measuring device, characterized in that the pressure measuring device comprises a fist pressure sensor (60) measuring the pressure at an outlet side of the pump and a second pressure sensor (61) measuring the pressure at an inlet side of the pump and means that calculate the differential pressure between the outlet side and the inlet side of the pump from the signals of both pressure sensors (60,61), and that a control unit (66) controls the rotational speed of the motor (21) as a function of a signal from the pressure measuring device.
