1. An implant for addressing pressure within a first body region, said implant comprising:

  • a conduit comprising a flow path and adapted to fluidly interconnect with the first body region; and

    a MEMS flow module disposed within said flow path, wherein said MEMS flow module comprises;

    a flow regulator, wherein said flow regulator comprises a first baffle; and

    a first plate, wherein said first plate comprises a first flow port, wherein said first baffle is aligned with said first flow port, and wherein said first baffle is movable relative to said first plate to change a magnitude of a spacing of said first baffle from said first plate in response to a change in differential pressure across said MEMS flow module;

    wherein the first plate comprises a first group of a plurality of the first flow ports and wherein the first baffle is aligned with each first flow port in the first group; and

    wherein said first baffle comprises a plurality of baffle flow ports, wherein said plurality of first flow ports in said first group and said plurality of baffle flow ports are arranged such that a flow through any given said first flow port must change direction to flow through any of said plurality of baffle flow ports.
