1. An apparatus for pumping blood, the apparatus comprising:
a pump housing having an outer wall radially disposed about a longitudinal pump axis, the pump housing having an upstream end and a downstream end;
an impeller positioned between the upstream end and the downstream end within the pump housing, the impeller supported by an upstream bearing and a downstream bearing, wherein the impeller includes a permanent magnet; and
a stator positioned circumferentially about the impeller and configured to impart a rotational motion to the impeller by applying a magnetic field to the permanent magnet of the impeller,
wherein the stator includes a stator housing, a stator core, and a hinge,
wherein a first semicircular portion of the stator housing and the stator core is pivotable, using the hinge, with respect to a second semicircular portion of the stator housing and the stator core, between an open position and a closed position, and
wherein the stator includes one or more sensors configured to provide a signal indicating whether the stator is in the open position or the closed position.
