    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: Systems and methods for a reduced-pressure interface for connecting a multi-lumen conduit to a distribution manifold. The interface includes a housing having a flange portion and a cavity wall portion. The cavity wall portion forms a cavity having a tissue-facing cavity opening. The interface further includes an attachment device, a conduit port, and a multi-lumen conduit. The attachment device is coupled to a tissue-facing side of the flange portion for coupling the housing to a sealing member. The conduit includes a distal end and a proximal whereby the distal end extends through a conduit aperture and past the cavity wall portion into the cavity. The conduit further includes a primary lumen and a plurality of sensing lumens. The primary lumen and the plurality of sensing lumens extend from the proximal end of the conduit to the distal end. The conduit is adapted to contact the distribution manifold.

    Abstract: Systems, apparatuses, and methods for providing negative pressure to a tissue site are disclosed. Illustrative embodiments may include an apparatus or system comprising a dressing for treating a tissue site with negative pressure. For example, the dressing may comprise or consist essentially of a manifold and a contact layer. In some embodiments, the manifold may have a tubular shape with a central axis. The contact layer may comprise a polymer film completely or substantially enclosing the manifold in some examples. In further embodiments, the dressing may comprise a plurality of fluid restrictions in the contact layer, the fluid restrictions configured to open or expand in response to a pressure gradient across the polymer film.

    Abstract: In some embodiments, a debridement tool may include a housing, a reduced-pressure lumen, a debridement head, an impeller, and a drive system. The debridement head may be moveable relative to the housing. The impeller may be positioned in fluid communication with the reduced-pressure lumen and be moveable relative to the housing by operation of reduced pressure being applied to the impeller. The drive system may be coupled between the impeller and the debridement head and be configured to impart movement from the impeller to the debridement head.

    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.
