Claim 4:
5. An implantable apparatus for pumping fluid in a human, comprising:
a fluid motor adapted and configured for converting a pressure differential of a flowing fluid into rotational energy, said fluid motor including a plurality of plates in parallel alignment in a stack rotatable about an axis, said fluid motor having two opposing sides, said fluid motor having a motor fluid inlet located along the periphery of the stack and a fluid motor outlet located centrally within the stack;
a first pumping element located on one side of said fluid motor and being driven to rotate by said fluid motor; and
a second pumping element located on the other side of said fluid motor and being driven to rotate by said fluid motor;
wherein fluid at a higher pressure is provided to the fluid motor inlet, flows within the stack, and is drained from the fluid motor outlet to the fluid at a lower pressure.
