Abstract: 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.

Abstract: A dressing interface includes a base that has an aperture and a plurality of microneedles that are attached to the base and disposed over the aperture. The interface also includes a port that is configured to receive a fluid conductor and a conduit that couples the port and the aperture. Each of the microneedles contains a passageway that is fluidly coupled to the aperture. The interface may be used with a drape that is placed over a tissue site. The interface may provide communication between the tissue site and a reduced-pressure source through the microneedles piercing the drape rather than by cutting a hole in the drape.

Abstract: An assembly includes a drape substantially sealable over a wound bed and a trackpad configured to couple a tube to the drape and allow the tube to provide suction to the wound bed. The assembly also includes a vent opening in the drape, a filter coupled to the drape and communicating with the vent opening, a cover coupled to the drape and movable between a first position to cover the vent opening and filter and a second position to uncover the vent opening and the filter, and a fluid indicator coupled to the drape and operable to provide a visual indication that fluid build-up is present in the wound bed.
