The paracardiac blood pump is destined for protruding through the cardiac wall into the heart with a portion of its housing ( 10 ) and for suctioning blood from the heart. The blood is pumped into one of the blood vessels connected with the heart through a line that extends outside the heart. A cannula ( 30 ) is arranged in front of the inlet ( 17 ) of the pump ring ( 16 ). The housing ( 10 ) and the cannula ( 30 ) have approximately the same outer diameters of 13 mm at most. The housing, together with the cannula ( 30 ), can thus be inserted into the heart through a puncture hole that is produced in the cardiac wall without removing material.
