The present invention is a pump and more specifically blood pumps, ventricular assist devices, and relates to artificial hearts. The natural heart functions in a fashion similar to this pump. Each of the two chambers of pumping has two check valves. The walls of the natural heart are made of muscle which provides power to pump blood. Mechanical blood pumps have been developed for use as artificial hearts to assisting the natural heart. There are two categories of blood pump. The first category uses a rotary impeller and it includes centrifugal pumps and axial flow pumps.

The other category is pulsatile pumps. One of the problems which are associated with available mechanical blood pumps is the formation of blood clots in the pump.  This is a serious issue and can result in the death of a human being. The object of this invention is to provide a blood pump that minimizes the incidence of blood clotting. The present invention improves the flow of the blood as well.
