Abstract
A pump for generating fluid flow in an elastic tubular conduit. The pump comprises a plurality of electrically operated valves, each valve being positionable adjacent to the conduit. Each valve has a valve head configured to alternate from a first position in which the lumen of the conduit adjacent to the valve head is unobstructed and a second position in which the lumen of the conduit adjacent to the valve head is obstructed. The pump also comprises a driver configured to control the positions of the valve heads, so as to execute a predetermined temporo-spatial array of valve head positions.
