1. A pumping device, comprising:

  • an outer lumen, formed of a substantially unbending material defining an inner surface inside the lumen, and an outer surface outside the lumen;

    an inner lumen, formed entirely within said inner surface within the outer lumen, said inner lumen formed of a material that is elastically deformable and having an inside surface which is adapted to receive a fluid therein;

    a fluid material, between said inner wall and said outer wall, said fluid material having a mechanical property that allows it to transmit applied force waves; and

    an actuator, that actuates said fluid material at a frequency that causes constructive wave interaction within the fluid material and drives a fluid flow through the inside surface of the inner lumen.
