Claim Text:
1. An apparatus for dressing a wound, comprising: a substantially gas impermeable, flexible mat; a plurality of projections extending from a surface of the substantially gas impermeable, flexible mat, each projection having a first end connected to the surface and a second end opposing the first end; and a flexible membrane positioned adjacent the second end of at least a portion of the plurality of projections, the flexible membrane being deformable by the at least a portion of the plurality of projections when a biasing force exerted on the substantially gas impermeable, flexible mat or the plurality of projections is greater than or equal to a threshold force, wherein the flexible membrane comprises a smooth surface adapted to promote epithelialization if the biasing force is less than the threshold force and a valve associated with at least one of the plurality of projections to present the smooth surface when the biasing force is less than the threshold force.
