<p>Pump apparatus operated by remote energy transfer, for implantation in the body of a subject. The apparatus includes a pump chamber having an inlet and an outlet, and comprising an exterior wall, which defines and contains a volume of a fluid therein. The chamber has a one-way inlet valve at the inlet thereof and a one-way outlet valve at the outlet.
