Abstract:
Dressings for tissue treatment with negative pressure and methods of using the dressings for tissue treatment with negative pressure, which may comprise a dressing having at least three layers assembled in a stacked relationship. The first layer may comprise or consist essentially of a polymer film having a plurality of fluid restrictions that are normally unstrained or closed. The second layer may comprise a manifold, and the third layer may comprise or consist essentially of a polymer drape. A fourth layer, which may be coupled to the first layer opposite the second layer, may comprise or consist essentially of a silicone gel having a plurality of apertures. In some examples, the plurality of apertures in the fourth layer may be registered with the fluid restrictions of the first layer.
