Abstract

The intracardiac blood pump (10) comprises a drive section (11) and a pump section (12). A flexible pump hose (14) is connected to the pump section (12). To lay the pump hose (14) from the right atrium (21) to the pulmonary artery (26) the distal end of the pump hose (14) comprises a balloon (35) which acts as guide element in the blood flow and is entrained by the natural blood flow. This facilitates placing of the blood pump in the heart.
