Claim Text:
1. A reduced pressure dressing adapted to distribute a reduced pressure to a tissue site, the dressing comprising: an interface layer adapted to be positioned at the tissue site; a first manifold layer positioned in fluid communication with the interface layer to distribute the reduced pressure to the interface layer; an absorbent layer in fluid communication with the first manifold layer to absorb liquid from at least one of the first manifold layer, the interface layer, and the tissue site; a diverter layer positioned adjacent the absorbent layer, the diverter layer formed from a substantially gas-impermeable material, the diverter layer including a plurality of spaced apertures in fluid communication with the absorbent layer, wherein the diverter layer includes a plurality of ridges on a surface of the diverter layer to define a plurality of channels between the ridges; a second manifold layer in fluid communication with the diverter layer to distribute the reduced pressure to the diverter layer; a cover to maintain the reduced pressure at the tissue site, the cover having an aperture through which the reduced pressure is adapted to be delivered to the dressing; and a liquid-air separator positioned between the second manifold and the cover to inhibit liquid from exiting the dressing.
