A cannula for use as for example on the inflow end of an implantable intravascular heart pump. The stiffness of the cannula is differentiated along its length, wherein its proximal end is stiffer than its distal end, while a substantially constant wall thickness is maintained along its entire length. Attached to the flexible distal end, is a rigid tip component having inlet ports and an interior surface profile that minimizes the risk of hemolysis and thrombogenisis.
