1. A method comprising:
providing a pump housing defining an elongate interior that extends along a length of the pump housing, wherein the pump housing includes a piston in the pump housing, wherein the piston includes a first plurality of lumens, and wherein each lumen of the first plurality of lumens has a length extending substantially parallel to the elongate interior;
pumping a fluid by oscillating the piston in the elongate interior in the pump housing, wherein, in a first mode, each cycle of the oscillating has a rate differential between piston movement in a first direction versus piston movement in a second direction opposite the first direction to cause more of the fluid to move in the first direction than in the second direction.
