1. A pump comprising:
a pump housing that is expandable and compressible; and
a rotor that is expandable and compressible and disposed in the pump housing, the rotor comprising at least one rotor blade, a hub, and an axis of rotation,
wherein, in an uncompressed state of the rotor, at least a portion of the at least one rotor blade extends from the hub toward an outer edge of the at least one rotor blade along a first axis,
wherein the first axis is offset a predetermined distance from a radial axis of the rotor that orthogonally traverses the axis of rotation,
wherein the first axis is eccentric with respect to a center of the hub and substantial parallel to e radial axis.
