Abstract: A medical drape for use with a reduced pressure system for providing reduced pressure to a tissue site is described. In some embodiments, the drape may include a flexible film, and an adhesive layer coupled to the flexible film. The adhesive layer may include a first adhesive disposed on a first portion of the flexible film in a first pattern. The first adhesive can be configured to secure the flexible film proximate to the tissue site. The adhesive layer generally includes a second adhesive disposed on a second portion of the flexible film in a second pattern. The second adhesive can be configured to seal the flexible film proximate to the tissue site. The first pattern and the second pattern are preferably registered so that the first portion and the second portion are offset to cover substantially different portions of the flexible film.

Abstract: A dressing for treating a tissue site, particularly a peritoneal or abdominal site, is disclosed. The dressing may comprise: a substrate; an adherent layer coupled to a surface of the substrate; and a fibrous layer comprising fibers coupled to a surface of the adherent layer opposite the substrate. Typically, the fibrous layer satisfies one or more of the following: at least 75% of the fibers are coupled approximately perpendicular to the surface of the substrate; at least 95% of the fibers in the fibrous layer have a length to diameter aspect ratio from about 10 to about 1000; and no more than 10% of the fibers are coupled approximately tangential to the surface of the substrate. Optionally, the fibrous layer may be formed by a flocking process. Methods of treating various tissue sites using the dressings and negative-pressure therapy are also disclosed.

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: Provided herein is a system and method for mitigating premature light deactivation of light deactivated adhesive drapes. One aspect provides a system comprising a drape, a photosensitive adhesive layer, and a release agent, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a filter layer to prevent the photosensitive adhesive from being exposed to deactivation wavelengths prematurely. The filter layer may be printed directly onto the drape and may be removable after exposure to a solvent, such as isopropyl alcohol (IPA). The filter layer may also be a filter adhesive layer. Another aspect provides a method for application and removal of a drape using by removing one or more of the filter layer and/or the filter adhesive layer and applying light to the drape to deactivate the photosensitive adhesive layer and promote easy, clean, and less painful removal of the drape.

Abstract: A wound treatment system comprises a wound-treatment apparatus and a wound dressing coupled to the apparatus. The wound dressing includes a foam structure wound insert having pores with a greater cross-sectional area when viewed from a first direction and a smaller cross-sectional area when viewed from an orthogonal direction. Methods for making such wound inserts may include compressing foam structure material having pores with a substantially uniform cross-sectional area. Methods for treating a wound using a wound insert.

Abstract: A treatment system for debriding a treatment area of a tissue site and applying negative pressure is disclosed. In some embodiments, the treatment system may include an ultrasonic bubble generator fluidly coupled to a negative-pressure source, fluid source, and a dressing. Fluid may be drawn from the fluid source to the ultrasonic bubble generator, whereby micro-bubbles and ultrasonic waves may be generated in the fluid before the fluid is instilled to the dressing.

Abstract: In an example is a system for providing treatment to a tissue site. The system may include a tissue interface for transporting fluid to the tissue site. The system may further include a cover for providing a sealed space including the tissue interface. The system may further include a negative-pressure source fluidly coupled to the tissue interface and providing negative pressure. The system may further include a hyperoxic fluid source fluidly coupled to the tissue interface and providing a hyperoxic fluid. The system may further include a controller for controlling the negative pressure and the hyperoxic fluid so as to maintain the sealed space at a negative pressure while the hyperoxic fluid is provided to the sealed space.

Abstract: Systems, methods, and apparatuses for forming a multi-function core for a dressing are described. The multi-function core includes a contact layer configured to be positioned adjacent to a tissue site, a wicking layer adjacent to the contact layer, an ion exchange layer adjacent to the wicking layer, an absorbing layer adjacent to the ion exchange layer, a blocking layer adjacent to the absorbing layer, and an odor-absorbing layer adjacent to the blocking layer. The contact layer, the wicking layer, the ion exchange layer, the absorbing layer, the blocking layer, and the odor-absorbing layer are coextensive and formed from a plurality of fibers disposed in a fibrous web. Methods of manufacturing the multi-function core are also described.

Abstract: A multi-layer dressing for treating tissue with negative pressure, instillation, or both. In some embodiments a first layer may be formed from reticulated foam having a series of holes. A second layer disposed adjacent to the first layer may be formed from a perforated polymer. The dressing may optionally include a third layer formed from a soft polymer, such as a silicone gel. The third layer may also have perforations or apertures. The third layer is generally oriented to face a tissue site, and may be disposed adjacent to the first layer so that the first layer is disposed between the third layer and the first layer. The perforations or apertures in the third layer may be registered with one or more perforations in the first layer.
