A multi-layer reduced pressure delivery apparatus is provided for applying
reduced pressure tissue treatment to a tissue site. The multi-layer
apparatus includes a tissue contact layer, a release layer, and a
manifold layer. The tissue contact layer includes a scaffold adapted to
contact the tissue site, the release layer includes a hydrogel-forming
material and a plurality of flow channels, and the manifold layer
includes a distribution manifold. The release layer is positioned between
the tissue contact layer and the manifold layer to allow easy release of
the manifold layer from the tissue contact layer following the
administration of reduced pressure tissue treatment.
