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.
