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.

Abstract: In one example embodiment, a system for treating a tissue site is disclosed comprising a dressing adapted to contact the tissue site and provide a fluid seal between a therapeutic environment and a local external environment, and a solution source fluidly coupled to the dressing and adapted to deliver an antimicrobial solution comprising a peroxy α-keto carboxylic acid, such as peroxy pyruvic acid, to the tissue interface. The system may further comprise a negative-pressure source fluidly coupled to the dressing and adapted to provide negative pressure to the therapeutic environment after delivery of the antimicrobial fluid to the therapeutic environment. In another example embodiment, a method for treating a tissue site is disclosed comprising positioning a tissue interface to contact the tissue site, covering the tissue interface and the tissue site with a drape to provide a fluid seal between the therapeutic environment and the local external environment, and delivering an antimicrobial solution comprising peroxy α-keto carboxylic acid to the therapeutic environment before providing negative pressure to the therapeutic environment.

Abstract: A system, apparatus and method for delivering negative pressure and vibrations proximate a wound site. The system comprises a dressing adapted to be fluidly coupled to the wound site and further adapted to translate vibrations to the wound site. A pad is coupled to a negative pressure source and to the dressing. The pad is also coupled to a vibration module. The system further comprises a drape covering the dressing and the pad and forming a seal between the wound site and the environment. The vibration module fluidly couples to the dressing and provides vibrations during application of negative pressure.

Abstract: A wound dressing includes a contact layer and a support layer. The contact layer is configured to engage and provide surface deformation, slough removal, or debride a wound bed and has a first side and a second side, the second side facing the wound surface. The support layer also has a first side and a second side, the second side facing the first side of the contact layer, wherein a portion of the support layer is configured to overlay a periwound surrounding the wound bed.

Abstract: Disclosed embodiments relate to devices and systems for providing both negative-pressure therapy and instillation, In some embodiments, both negative-pressure and instillation may be provided to a tissue site in a low-profile context that may also prevent siphoning of instillation fluid during negative pressure application. For example, a single bridge may include a negative-pressure pathway with supports and an instillation pathway, and the instillation pathway may be configured with respect to the negative-pressure pathway so that at least a portion of the instillation pathway collapses upon application of negative pressure to the negative-pressure pathway. Collapse of at least a portion of the instillation pathway may be sufficient to close the instillation pathway.

Abstract: A dressing interface for connecting a negative-pressure source to a dressing may have a coupling member comprising an aperture, a first adhesive region having a first region peel strength, and a second adhesive region having a second region peel strength less than the first region peel strength. The dressing interface may further have a flange coupled to the coupling member, and a conduit housing coupled to the flange and extending through the aperture in the contact layer.

Abstract: In some non-limiting examples, a system for stimulating tissue growth at a tissue site may include an interactive body including a body mass and a tissue contact surface configured to contact the tissue site. A plurality of struts and a plurality of voids may be exposed at the tissue contact surface, and may define a tissue interface pattern at the tissue contact surface. The tissue interface pattern may be configured to engage the tissue site and to create tissue deformation in combination with the body mass. Also provided are other systems, apparatus, and methods suitable for stimulating tissue growth.

Abstract: Systems and methods for providing negative-pressure therapy with fluid instillation therapy and, more specifically, scheduling and controlling both the negative pressure therapy and the fluid instillation therapy are described. The method may comprise applying negative pressure to the dressing based on an initial therapy configuration, and monitoring negative pressure parameters associated with the application of negative pressure to the dressing to identify negative pressure alarm conditions. The method may further comprise applying instillation fluid to the dressing based on the initial therapy configuration, and monitoring instillation parameters associated with the application of instillation fluid to the dressing to identify instillation alarm conditions. Both may include modifying the initial therapy configuration to generate a modified therapy configuration in response to the negative pressure and instillation alarm conditions identified.

Abstract: In an example embodiment, a dressing for disrupting debris in a tissue site may comprise a manifold having a first face and a second face. The dressing may also include a plurality of surface features formed from a compressible material. The plurality of surface features may define channels on at least the first face of the manifold. The channels may receive tissue in response to the application of negative pressure. In another example embodiment, a system for softening tissue at a tissue site may include a contact layer. The contact layer may include at least two concentric edges and at least one frangible strut mechanically coupling the concentric edges. The concentric edges and the frangible strut may define through-holes in the contact layer. The through-holes in the contact layer may have an open area in a range of about 0.25 square centimeters to about 15 square centimeters.
