Abstract: Dressings, systems, and methods for treating a tissue site with negative pressure are described. The dressing includes a manifold having a first surface and a second surface opposite the first surface, 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 are formed from a polymer film. A plurality of fluid restrictions are formed in the polymer film adjacent to at least the first surface. A first plurality of bonds is formed between the first layer and the second layer. The first plurality of bonds define separable sections of the manifold. A second plurality of bonds is formed between the first layer and the second layer. The second plurality of bonds define a plurality of openings.

Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a plurality of apertures and may be adapted to cover the tissue site. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. A conduit comprised of an absorbent material that is vapor permeable and liquid impermeable may be in fluid communication with the dressing for providing reduced pressure to the dressing. Other dressings, systems, and methods are disclosed.

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, a release agent, and an optical fiber mesh layer configured as a light pipe, 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. Another aspect includes a pipe light pipe, as an alternative to the optical fiber mesh layer. The systems may have a removable blocking layer to prevent the photosensitive adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using the light pipe to transport or route light to the drape to deactivate the photosensitive adhesive layer and promote easy, clean, and less painful removal of the drape.

Abstract: A porous conduit may be suitable for use in treating a tissue site, and may include a central lumen and a porous wall positioned substantially concentric about the central lumen. The porous wall may have an open porous structure that may define a plurality of interconnected pores in fluid communication with one another. As part of a system, the porous conduit may be used with a manifold adapted to be positioned at a tissue site, a sealing drape adapted to cover the manifold to provide a sealed space relative to the tissue site, and a therapy device including a reduced-pressure source. The porous conduit may be disposed in the sealed space and in fluid communication between the sealed space and the reduced-pressure source.

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 reduced-pressure treatment system for debriding a treatment area of a tissue site and applying reduced pressure is disclosed. The reduced-pressure treatment system includes a hydrogel having a blocked acid debriding agent. The hydrogel is adapted to cover the treatment area and enhance autolytic debridement at the treatment area. The reduced-pressure treatment system includes a manifold that is adapted to cover the hydrogel and distribute reduced pressure to the tissue site. The reduce-pressure treatment system also includes a sealing drape for forming a fluid seal over the tissue site and manifold. Other systems, methods, and dressings are presented.

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.
