A biomedical apparatus for pumping blood of a human or an animal patient through a secondary blood circuit is provided, including a blood pump, an inlet duct and an outlet duct for guiding blood of the patient to the blood pump and back to the patient. The apparatus further includes a measuring device with at least one pressure sensor for measuring pressure values in the patient's circulatory system. A controller is provided that includes at least two different preset control algorithms for regulating the operating point of the blood pump based on the measured pressure values. The controller is configured to select one of these preset control algorithms for being applied in dependence on the position of the at least one pressure sensor in the patient's circulatory system.

Biomedical apparatus with a pressure-regulated blood pump

A biomedical apparatus for pumping blood of a human or an animal patient through a secondary blood circuit is provided, including a blood pump (), an inlet duct () and an outlet duct () for guiding blood of the patient to the blood pump () and back to the patient. The device further includes a measuring device () for measuring a physical parameter of the heart () or of a blood vessel, and a controller () for regulating the power of the blood pump (). The measuring device () is adapted to be arranged inside the heart () or the blood vessel, and the controller is configured to determine an estimate for an inner volume of the heart () or of the blood vessel based on the physical parameter and is configured to regulate the power of the blood pump () depending on this estimate.
