Claim 12:
13. An implantable apparatus for pumping fluid in a human, comprising:
a housing comprising a biocompatible material and adapted and configured for implantation in a human;
a fluid motor located in said housing and 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 and rotatable about an axis, said plurality of plates having a centrally located fluid outlet;
a manifold statically supported by said housing and surrounding the periphery of said plurality of plates, said manifold having an inlet and providing fluid from the manifold inlet to the plurality of plates;
a pump located in said housing and including a first centrifugal pumping element and a second centrifugal pumping element, said pump having a plane of symmetry with said first pumping element and said second pumping element being located on opposite sides of the plane of symmetry, said pump being driven to rotate by said fluid motor;
wherein fluid at a higher pressure is provided to the manifold inlet, flows between said plurality of plates, and is drained from the centrally located fluid outlet.
