ABSTRACT:
A blood pumping device is described for internal use in humans or animals and which is particularly suitable for use as a left ventricular assist device. The device is comprised of a unitary pancake-shaped deformable sac of flexible resilient, blood compatible material. A pair of oppositely acting plates on each side of the pancake-shaped sac are moved toward and away from each other by the action of driving means to deform the sac and provide the pumping action. Inlets and outlets are arranged in the annular side wall of the sac.
