Some embodiments may further comprise one or more fluid bridges pneumatically linking adjacent separable sections across intervening seams, which may improve manifolding. The fluid bridges in some embodiments may be configured to minimize risk of in-growth.

ANTIMICROBIAL/ANTIBACTERIAL DISRUPTIVE DRESSING FOR USE WITH NEGATIVE PRESSURE AND FLUID INSTILLATION
Dressings, systems, and methods for treating a tissue site are described herein. The dressing has a contact layer having a plurality of holes. The contact layer is configured to be positioned adjacent to the tissue site. The dressing also includes a cover layer having a first side configured to be positioned adjacent to the contact layer and a second side opposite the first side. An antimicrobial agent is coupled to the first side of the cover layer. The dressing has a drape configured to be positioned over the cover layer to form a sealed space having the contact layer and the cover layer disposed in the sealed space.

DRESSING WITH EPITHELIALIZATION AND SCAR REDUCTION FEATURE
Provided are systems, dressings, and methods suitable for treating a tissue site, such as an incision or linear wound, for example. The systems, dressings, and methods relate to a dressing assembly that may include a dressing bolster, a comfort layer, and a polymeric enhancement layer. The dressing bolster may include foam and may have a first side and a second side. A first side of the comfort layer may be coupled to the second side of the dressing bolster, and a first side of the polymeric enhancement layer may be coupled to the second side of the comfort layer. An opposing second side of the polymeric enhancement layer may be configured to directly contact the tissue site. Other systems, dressings, apparatuses, and methods are disclosed.

HAND DRESSING FOR USE WITH NEGATIVE PRESSURE WOUND THERAPY
A dressing includes a barrier film layer, a wound contact layer coupled to the barrier film layer, and a plurality of felted foam strips positioned between the barrier film layer and the wound contact layer. Each strip provides a manifolding pathway. The barrier film layer and the wound contact layer include a central region and a plurality of peninsular projections extending therefrom in the shape of a hand.

LOW-PROFILE FLUID CONDUCTORS WITH MOISTURE MANAGEMENT FEATURES
An apparatus for conducting fluid may comprise a first layer, a second layer, and a third layer sealed to form a first fluid pathway and a second fluid pathway in a stacked relationship. An aperture may be disposed at a first end of the second fluid pathway. Upon the application of a negative pressure, fluid may be drawn through the third aperture, into the second fluid pathway, and through the first fluid pathway. The apparatus may be fluidly coupled to a dressing at a tissue site. At least a portion of the third layer may be configured to allow moisture to evaporate from a periwound into the second fluid pathway. The fluid drawn through the third aperture may aid in removal of the evaporated moisture within the second fluid pathway, as well as moisture directly from the periwound, to reduce the risk of maceration to the periwound.

A61F 13/00 - Bandages ou pansements; Garnitures absorbantes
Disclosed dressing embodiments may include a tissue interface and a cover, with the tissue interface shaped anatomically for interaction with a specific anatomical region, such as a foot. Such tissue interface embodiments would typically comprise a manifold and a fluid control layer having a plurality of fluid restrictions, with the manifold disposed in a stacked relationship with the fluid control layer. Some embodiments of the tissue interface might also include a gel layer in a stacked relationship with the fluid control layer, opposite the manifold. For foot dressings, tissue interface embodiments may be shaped with a hindfoot section, an underfoot section, and a forefoot extension section.
