1. A centrifugal blood pump comprising:
a housing having a pumping chamber, an inlet with an inlet axis, and an outlet with an outlet axis, the inlet and the outlet being in fluid communication with the pumping chamber;
an impeller rotatably disposed within the pumping chamber;
at least one bearing supporting the impeller within the pumping chamber; and
a strut connected to the housing at the inlet to support at least a portion of the bearing mechanism,
wherein the strut is fixed directly to an inner sidewall of the housing at a fixation point at a circumferential position about the inlet axis such that a major axis of the strut and the outlet axis define a predetermined angle in a cross-sectional plane perpendicular to the inlet axis, wherein a first axial end of the strut proximate the inlet extends from the inner sidewall of the housing towards the inlet axis at an angle of 15° to 75° relative to the inlet axis.
