Abstract: Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

Abstract: A sealing member for providing a seal over a tissue site and a method of making the same is described. The sealing member includes a film layer; a first adhesive coupled to and coextensive with the film layer; and a second adhesive coupled to and coextensive with the first adhesive. A plurality of apertures extend through the second adhesive. Each aperture defines an interior surface between a first side and a second side of the second adhesive. The interior surface intersects the first side to form a first edge and intersects the second side to form a second edge, the interior surface comprising a chamfer. The first adhesive is configured to extend at least partially through the plurality of apertures.

Abstract: According to an illustrative embodiment, a system for treating a wound at a tissue site of a patient comprising a reduced-pressure source to supply reduced pressure, a drape adhering to the tissue site to cover the wound where possible leak passages between the drape and the tissue site may occur, and a seal disposed between the drape and the tissue site, is disclosed. The seal is adapted to react with a fluid to form a sealant substantially filling the passages in response to air leaking through the passages from outside the drape when reduced pressure is applied to the wound. According to another illustrative embodiment, a method for sealing a drape to a tissue site for treating a wound at the tissue site comprising applying the drape to cover the tissue site whereby passages are formed between the drape and the tissue site, positioning a seal between the drape and the tissue site wherein the seal is adapted to react with a fluid to form a sealant for substantially filling the passages, is also disclosed.

Abstract: A flexible dressing for applying to a tissue site for determining the extent of debridement required to remove non-viable tissue is disclosed. Some embodiments of the dressing may be in the form of a multi-layer drape having an integrated tissue viability indicator system. Some embodiments may also include a system of shapes or a grid pattern printed or embossed on a surface of the drape for providing guidance during an ensuing debridement or amputation procedure.

Abstract: Reduced-pressure sources, systems, and methods involve using a vacuum pump that is disposed within a sealed space to produce reduced pressure. The exhaust from the vacuum pump is exhausted from the sealed space through pores in an enclosure member that is made of a polymeric, porous, hydrophobic material. Other devices, systems, and methods are disclosed.

Abstract: A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.

Abstract: Dressings, systems, and methods are disclosed that, in some embodiments, relate to treating a tissue site. In one embodiment, a dressing may include a manifold, a retention pouch, a sealing member, and a conduit interface. The manifold may be adapted to distribute reduced pressure to the tissue site, and the retention pouch may be adapted to retain and manage fluid extracted from the tissue site. The sealing member may cover the retention pouch and the manifold to provide a sealed space with the tissue site. The conduit interface may be in fluid communication with the sealed space and an exterior surface of the sealing member. The dressing may be utilized with a therapy device operable to control reduced pressure in the dressing and fluid flow over the sealing member.

Abstract: A system for treating a tissue site includes a reduced-pressure source to apply reduced pressure, a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site, and a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape includes an adhesive layer for sealing the drape to the tissue site to create a sealed space having the manifold therein, and a non-adhesive layer formed from a portion of the adhesive layer. A method for manufacturing a medical drape includes providing a sheet of adhesive material and treating a side of the sheet of adhesive material to form a non-adhesive layer and an adhesive layer. The method laminates a release liner adjacent the adhesive layer.
