Abstract
A pump includes a conduit defining an inner volume and formed from a flexible material, the conduit movable between an expanded state and a relaxed state. A coil is disposed within the conduit and includes an outer diameter that is approximately equal to an inner diameter of the conduit, the coil substantially maintaining its outer diameter when the conduit is moved between the relaxed state and the expanded state. A manifold is in fluid communication with the inner volume and is operable to permit fluid to enter the inner volume in a first mode and expel fluid from the inner volume in a second mode.
