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 ( 1 ) comprising a body ( 3 ), encompassing an inflow-lumen ( 4 ), extending essentially axially along a center-line ( 5 ), having a distal-end ( 6 ) for an attachment of the inflow-lumen ( 4 ) to said blood handling system, and having a proximal-end ( 7 ) for an introduction of blood from the heart ( 2 ) and/or from the associated vessel into the inflow-lumen ( 4 ). At the proximal-end ( 7 ) at least one angled-hole ( 8 ), extending around a longitudinal hole-axis ( 9 ) is provided, and said hole-axis ( 9 ) includes a presettable hole-angle (alpha) with the center-line ( 5 ) of the inflow-lumen ( 4 ), wherein said body ( 3 ) of the pump-inflow-cannula ( 1 ) comprises a reinforcement-means ( 10 ). The invention is also related to a pump-outflow-cannula ( 23 ) and to a blood managing system comprising a pump-inflow-cannula ( 1 ) and a pump-outflow-cannula ( 23 ) in accordance with the present invention. |
