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: A dressing may include a first layer comprising a polymer film having a plurality of perforations. A second layer may comprise a manifold. A cover comprising a polymer film may be disposed adjacent to the second layer. The first layer, the second layer, and the third layer may be stacked so that the second layer is disposed between each of the first layer and the third layer. The second layer may have a length of at least 12 centimeters and not greater than about 32 centimeters. The second layer may have a thickness of between 7 millimeters and 9 millimeters. In some embodiments, the second layer may have a perimeter that is exposed between the first layer and the cover, which can allow the dressing to be customized for size and shape. The manifold may be configured to maintain at least 80% of an applied negative pressure through the length.

Abstract: In some examples, a dressing suitable for treating a tissue site may include a sealing member configured to form a sealed enclosure relative to the tissue site. A fluid buffer may be configured to be positioned at a sealing member aperture in fluid communication between the sealed enclosure and an ambient environment external to the sealed enclosure. Other dressings, apparatus, systems, and methods are disclosed.

Abstract: A citric acid containing dressing for treating a tissue site with negative pressure may comprise a cover, a manifold, and a perforated polymer film and/or a sealing layer. The sealing layer can be a perforated silicone gel having a treatment aperture. The dressing can further contain an adhesive. The cover, the manifold, and the perforated polymer film and/or the sealing layer may be assembled in a stacked relationship with the cover and the sealing layer enclosing the manifold. Citric acid may be present on or incorporated in, for example, the perforated polymer film and/or the sealing layer.

Abstract: A dressing for treating a tissue site with negative pressure includes a manifold having a first surface and a second surface opposite the first surface. The dressing also includes a first layer adjacent to the first surface and a second layer adjacent to the second surface. The first layer and the second layer each include a polymer film. The dressing also includes a plurality of fluid restrictions in the polymer film adjacent to at least the first surface, and a plurality of bonds between the first layer and the second layer. The plurality of bonds defines separable sections of the manifold. Each of the separable sections of the manifold has at least one rounded edge.

Abstract: An evaporative bridge dressing that may be used with negative-pressure treatment of tissue. The evaporative bridge dressing may have one or more fluid transfer layers comprised of high-density wicking material enclosed between layers of film having high moisture-vapor transfer rates to manage liquid storage and pressure drop. The evaporative bridge may have an absorbent in some embodiments. An evaporation channel may be disposed adjacent to or combined with the evaporative bridge. A means for measuring pressure across the evaporative bridge may include a feedback path. A support means may reduce or prevent collapse of one or more of the evaporative bridge, the evaporation channel, the feedback path.

Abstract: A dressing or wound filler comprising a laminate structure of film materials. In one example embodiment, a dressing may include a first layer comprising a first film, a second layer adjacent to the first layer and comprising a second film, and a third layer comprising a material having closed cells. The first layer may further include a plurality of fluid restrictions. The second layer may include blisters and apertures to allow fluid transfer through the second film. The third layer may include closed cells and apertures between the closed cells to allow fluid transfer through the third layer. The dressing may further include a fourth layer adjacent to the third layer opposite the second layer, which may include a fourth film having blisters and apertures. The dressing may also include a fifth layer, which may be adjacent to the fourth layer opposite the third layer. The fifth layer may include a film and a second plurality of fluid restrictions.

Abstract: Systems, methods, and apparatuses for generating and releasing iodine are described. Some embodiments may include a dressing member including a plurality of iodine-forming reagents and a water-swellable material. In some embodiments, the dressing member may include water-swellable fibers. The water-swellable fibers may each include a water-swellable material in which iodine-forming reagents are dispersed. As liquid comes into contact with and is absorbed by the water-swellable material, the iodine-forming reagents may come into contact with each other, causing an iodine-forming reaction to occur, producing iodine.

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.
