Abstract
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 water-soluble polymer 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.

A reduced pressure delivery system for applying reduced pressure tissue treatment to a tissue site comprising:
- a multi-layer reduced pressure delivery apparatus having a tissue contact layer, a release layer, and a manifold layer, the tissue contact layer including a scaffold adapted to contact the tissue site, the release layer including a water-soluble polymer and a plurality of flow channels, the manifold layer including a distribution manifold, the release layer being positioned between the tissue contact layer and the manifold layer, the water-soluble polymer of the release layer binding to at least one of the tissue contact layer and the manifold layer;
- and
- a reduced-pressure delivery tube fluidly connected to the manifold layer to deliver a reduced pressure to the tissue site.
A multi-layer reduced pressure delivery apparatus for applying reduced pressure tissue treatment to a tissue site comprising:
- a first layer having a scaffold adapted to contact a tissue site;
- a second layer having a water-soluble polymer and a plurality of flow channels, the water-soluble polymer contacting the scaffold;
- and
- a third layer having a distribution manifold contacting the water-soluble polymer.
A multi-layer reduced pressure delivery apparatus for applying reduced pressure tissue treatment to a tissue site comprising:
- a tissue contact layer having a scaffold adapted to contact the tissue site to receive in-growth of new tissue from the tissue site, the tissue contact layer further having a first plurality of flow channels;
- a manifold layer having a cellular material to distribute a reduced pressure to the tissue site, the manifold layer further having a third plurality of flow channels;
- and
- a release layer positioned between the tissue contact layer and the manifold layer, the release layer including a water-soluble polymer connected to at least one of the tissue contact layer and the manifold layer, the water-soluble polymer adapted to dissolve following hydration by a fluid to release the at least one of the tissue contact layer and the manifold layer, the release layer further having a second plurality of flow channels in fluid communication with the first and third plurality of flow channels.
A reduced pressure delivery system for applying reduced pressure tissue treatment to a tissue site comprising:
- a reduced pressure delivery apparatus having a distribution manifold to distribute a reduced pressure and a scaffold to encourage in-growth of new tissue from the tissue site, the distribution manifold and scaffold being bound together by a water-soluble polymer positioned between the distribution manifold and the scaffold;
- and
- a reduced-pressure delivery tube having a distal end fluidly connected to the distribution manifold to deliver the reduced pressure through the distribution manifold and scaffold to the tissue site.
