The invention relates to a pump-inflow-cannula ( 1 ) providing a blood conduit from a heart ( 2 ) and/or from an associated vessel to an external blood handling system. Said pump-inflow-cannula comprises a body ( 3 ), encompassing an essentially axially extending inflow-lumen ( 4 ), having a distal-end ( 5 ) for an attachment of the inflow-lumen ( 4 ) to said blood handling system, and having a proximal-end ( 6 ) for an introduction of blood from the heart ( 2 ) and/or from the associated vessel into the inflow-lumen ( 4 ), wherein at least one projection ( 7 ) is provided at the proximal-end ( 6 ) to deflect a heart muscle from intruding into the inflow-lumen ( 4 ), wherein said body ( 3 ) of the pump-inflow-cannula comprises a reinforcement-means ( 8 ). The invention is also related to a pump-outflow-cannula ( 19 ) and to a blood managing system comprising a pump-inflow-cannula and a pump-outflow-cannula in accordance with the present invention. |
