1. A blood pump having a central axis and comprising:
a shroud extending generally along the central axis, the shroud comprising an inlet for incoming blood flow and an outlet for outgoing blood flow;
an impeller positioned within the shroud and extending generally along the central axis;
a motor including a motor body disposed proximal to and coupled with the impeller, the motor extending generally along the central axis and configured to impart rotation to the impeller;
a stator hub disposed adjacent to the motor body, the stator hub flaring radially outward in a proximal direction from a distal portion disposed at or within the shroud to a proximal portion spaced away from the shroud, the stator hub being stationary when rotation is imparted to the impeller by the motor; and
a pillar having a first end coupled with a proximal portion of the shroud at the outlet of the shroud, the pillar extending to a second end opposite to the first end, the second end coupled to the motor body, a length of the pillar between the first end and the second end being unconnected to the stator hub, the pillar disposed non-parallel to the central axis.
