| description | A rotary blood pump is described. The rotary blood pump (10) comprising a housing defining a pumping chamber (3) with upper and lower interior surfaces and having a blood inlet (7) and a tangential blood outlet (13), and a rotatable impeller (22) within the pumping chamber (3) and adapted to increase blood pressure within the pumping chamber (3) to cause blood to move to the blood outlet (13). The impeller (22) has at least one raised surface area adjacent the upper interior surface of the pumping chamber (3). The raised surface area comprises a hollow cylindrical casing (53) having a plurality of sidewalls to define a cavity (54) beneath said one raised surface area. The cavity is bounded by at least one solid wall member having a plurality of side-by-side balancing bores (56) formed therein to cause said impeller to rotate smoothly. |
