A circulatory apparatus for assisting the movement of fluids with a pulsatile flow. The circulatory apparatus includes a restrictable tube, an element for passively restricting a segment of the tube, two or more elements for selectively restricting segments of the tube, and a controller for directing selective restricting elements. The controller directs restricting elements in a manner that provides a cyclical pulsatile pattern of restriction along the length of the tube.
