Abstract: Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure treatment device to treat a tissue site with reduced pressure may include a pump control unit fluidly separate from a collection unit. Pump energy may be provided by the pump control unit to deflect one or more diaphragms within the collection unit to create reduced pressure. Other systems, devices, and methods are presented.

Abstract: A dressing for treating tissue with negative pressure is provided herein comprising a composite of dressing layers, including a release film, a perforated coated polymer film, a manifold, and an adhesive cover. Additionally, a method of manufacturing the dressing may comprise applying a cross-linkable polymer to a polymer film, curing the cross-linkable polymer to a gel layer to form a coated polymer film, and perforating the coated polymer film to form fluid restrictions, such as slits and/or slots, though the coated polymer film.

Abstract: This disclosure includes wound dressings and systems for effluent management of topical wound therapy and related methods. Some devices, which are configured to dilute therapeutic gas effluent flowing from a dressing, comprise a therapeutic gas source configured to provide therapeutic gas to the dressing; a container comprising a sidewall that defines a chamber configured to receive therapeutic gas effluent from the dressing; a negative pressure source configured to be coupled to the container such that the negative pressure source can be activated to draw fluid from the dressing through the chamber of the container; and a diluent gas source configured to deliver a diluent gas to dilute therapeutic gas effluent before the therapeutic gas effluent enters the negative pressure source.

Abstract: In some embodiments, a dressing assembly may include a dressing bolster, an interface seal, and a base layer. The dressing bolster may include a first side, a second side, and a periphery. The interface seal may be coupled at the periphery of the dressing bolster. The base layer may include a base layer flange configured to be coupled to the dressing and to extend beyond the periphery of the dressing bolster. The dressing assembly may be suitable for treating a tissue site with reduced pressure and for creating an apposition force between a first portion of the tissue site and a second portion of the tissue site. Other systems, apparatus, and methods are disclosed.

Abstract: A reduced pressure dressing for applying reduced pressure treatment to a tissue site includes an interface layer adapted to be positioned at the tissue site. An absorbent layer is in fluid communication with the interface layer to absorb liquid from at least one of the interface layer and the tissue site. A pump is in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site. A cover is positioned over the pump, the absorbent layer, and the interface layer to maintain the reduced pressure at the tissue site, and a liquid-air separator is positioned between the absorbent layer and the pump to inhibit liquid from entering the pump.

Abstract: A sealing drape may be suitable for use with a reduced-pressure treatment system for treating a tissue site. The sealing drape may have an interior surface adapted for positioning adjacent to a peripheral surface of the tissue site. The sealing drape may include a sealing material and an absorbent material. The sealing material may be hydrophobic and substantially free of hydrophilic components. Further, the sealing material may be positioned between the interior surface of the sealing drape and the absorbent material. The sealing drape may be used with a manifold for positioning at the tissue site, a reduced-pressure interface, and a reduced-pressure source. Methods of manufacture and treatment are also disclosed.

Abstract: A reduced-pressure system for treating a tissue site on a patient includes a distribution manifold that adheres to a tissue site to allow retention without external support. The distribution manifold includes a porous member and a tissue-fixation element. The tissue-fixation element maintains the porous member substantially adjacent to the tissue site while a sealing member is applied. In one instance, the tissue-fixation element is a soluble adhesive that partially covers either the tissue-facing side of the porous member or a tissue-facing side of a fluid-permeable substrate layer that is on the tissue-facing side of the porous member. Other systems, distributions manifolds, and methods are presented.

Abstract: Systems, methods, and dressings for treating a linear wound, such as an incision, on a patient are presented. The systems, dressings, and methods involve a sealed wound dressing assembly that helps form a fluid seal around the linear wound while simultaneously encompassing a subcutaneous delivery conduit to deliver fluid to or from a subcutaneous tissue site. In one instance, a reduced-pressure interface is used to allow the subcutaneous delivery conduit to pass through tissue at or near the linear wound and through a wound dressing assembly to a drainage receptacle.

Abstract: Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

Abstract: A system for treating a tissue site of a patient includes a dressing filler adapted to be positioned at the tissue site. The dressing filler includes a porous substrate having at least one compressed region and at least one expanded region. The compressed region of the porous substrate is held in a compressed state by a first coating capable of dissolving in the presence of a fluid, and the expanded region of the porous substrate is held in an expanded state by a second coating.
