• and
• a peristaltic pump disposed within the housing, the peristaltic pump comprising:
• a deformable conduit comprising a conduit lumen extending therethrough, the conduit lumen in fluid communication with the aspiration lumen;
• a roller in contact with the deformable conduit and comprising an outer peripheral surface forming a majority of an outer surface area of the roller, the roller engaged with the deformable conduit to cause the deformable conduit to deform;
• and
• a roller driver in contact with the outer peripheral surface of the roller, the roller movable along the deformable conduit in response to movement of the roller driver to cause movement of the material within the conduit lumen therealong;
• wherein the peristaltic pump comprises a plurality of rollers arranged in a circular configuration, and wherein the plurality of rollers are in contact with the deformable conduit and disposed between the deformable conduit and the roller driver;
