This disclosure includes pumping apparatuses and methods of using the same. Some apparatuses include a pump housing having one or more walls extending from a proximal end to a distal end, a hub rotatably coupled to the proximal end, and a peristaltic pump coupled to the hub and configured to cause fluid flow through a flexible tube when the hub is rotated relative to the pump housing, where at least a portion of the pump is disposed within the pump housing. Some apparatuses include a rotor and an interior cam surface, where the rotor is configured to cause fluid flow through a flexible tube as the hub is rotated by compressing at least a portion of the flexible tube between the rotor and the interior cam surface. Some apparatuses are configured to be coupled in fixed relation to a housing of a driver.
