1. An apparatus for treating a wound on a body with negative pressure, comprising:

  • a substantially liquid impermeable backing layer capable of forming a relatively fluid-tight seal or closure over a wound;

    a manifold member formed from a liquid impervious material positionable beneath the backing layer, the manifold member comprising;

    a plurality of separate, flexible flow channels extending in a radial direction away from a middle portion of the manifold member; and

    at least one opening formed in each of the flow channels, the openings being in communication with the flow channels and the wound so that negative pressure can be communicated through the flow channels and the openings to the wound and so that liquid can be removed from the wound through the flow channels;

    foam positionable beneath the backing layer; and

    an outlet conduit having an end portion mounted adjacent to a center portion of the backing layer.
