Abstract
A vacuum pump system for a prosthesis includes an enhanced suspension mechanism and incorporates a vacuum pump system, an adaptor assembly, circuitry, and a power source. A virtually air-tight seal between a residual limb and a socket of the prosthesis allows a vacuum fit to be generated by the pump system. The pump system may be controlled with various circuits and processors receiving instructions from a software program. The pump system may be located within a pylon, but yet remain vibrationally and acoustically de-coupled from the pylon.
