11. A pump comprising:
a conduit defining an inner volume and movable between an expanded state and a relaxed state, an effective length of the conduit being increased when moved from the relaxed state to the expanded state;
a coil disposed within the conduit, substantially filling the conduit, including an outer diameter that is approximately equal to an inner diameter of the conduit, and having an effective length that is increased when the conduit is moved from the relaxed state to the expanded state, the coil substantially maintaining its outer diameter and the inner diameter of the conduit when the conduit is moved between the relaxed state and the expanded state; and
a manifold in fluid communication with the inner volume and operable to permit fluid to enter the inner volume in a first mode and expel fluid from the inner volume in a second mode.
