Abstract
A pump includes a flexible conduit, at least one valve attached to the flexible conduit about the perimeter of the valve; and a drive mechanism to move the valve to pump blood within the conduit. The drive mechanism can, for example, be adapted to complete a single stroke during each heart ventricle contraction and/or to complete multiple strokes (that is, oscillate) during a single contraction. The moveable valve includes a plurality of openings. Each of the plurality of openings has a closure mechanism in operative connection therewith which is operable to at least partially close the opening to which it is operatively connected when the moveable valve is moved forward and to open the opening to which it is operatively connected when the valve is moved rearward. In one embodiment, each closure mechanism includes a flap of resilient material.
