    Abstract: A dressing for treating tissue may be a composite of dressing layers, including a contact layer, a manifold layer, and an adhesive drape. The manifold layer may include one or more layers of felted open-cell foam in some examples. The manifold layer may be relatively thin to reduce the dressing profile and increase flexibility, which can enable it to conform to difficult geometry and other tissue sites under negative pressure. The dressing may have a length and a width less than the length. The manifold layer may include a population of holes extending at least partially therethrough, wherein the holes may be configured to promote anisotropic contraction of the dressing parallel to its width. The population of holes may have a circular, ovoid, triangular, square, hexagonal, irregular, or morphous shape. The dressing may be a bolster that may anisotropically contract to provide a closing force to a linear wound.

    Abstract: Dressing embodiments may include a first layer comprising a polymer film having a plurality of perforations, and a second layer comprising a manifold. In some embodiments, the second layer may have a length of at least 12 centimeters. In some embodiments, the second layer may have a thickness of between 7 millimeters and 10 millimeters. In some embodiments, the manifold may comprise a plurality of slits configured to provide conformability. The manifold may also be configured to maintain at least 80% of an applied negative pressure through the length.

    Abstract: A dressing for an internal cavity may include a connector, a negative pressure pathway layer, an instillation pathway layer, a negative pressure manifold, and an instillation manifold. The negative pressure manifold can be disposed within the negative pressure pathway layer and the instillation manifold can be disposed within the instillation pathway layer. A proximate end of the negative pressure manifold can be fluidly coupled with a first channel of the connector. The proximate end of the instillation manifold can be fluidly coupled with a second channel of the connector. The negative pressure pathway layer and the instillation pathway layer can be configured to cooperatively form an inner volume therebetween. The inner volume may be configured to receive a space filler. The negative pressure pathway layer, the instillation pathway layer, and the space filler can be collectively configured to be positioned within the internal cavity.

    Abstract: A conduit includes a first end configured to be fluidly coupled to a wound site, and a second end configured to be fluidly coupled to a canister. The conduit additionally includes a central lumen extending between the first end and the second end. The conduit further includes a male interlocking member on a first side of the conduit and a female interlocking member on a second side of the conduit. Both the first side and the second side extend along a length of the conduit between the first end and the second end. The female interlocking member is configured to receive the male interlocking member.

    Abstract: A dressing or wound filler comprising a laminate structure of materials. In one example embodiment, a dressing may include a first layer comprising a first film, a second layer adjacent to the first layer and comprising a foam, and a third layer comprising a second film. The first layer and the second layer may further include a plurality of perforations or fenestrations. The third layer may include a plurality of raised features. The perforations or fenestrations of the first and second layers may be positioned or aligned with the raised features of the third layer so as to facilitate tearing of the dressing for sizing and application purposes. In some embodiments, the first layer may comprise a polyurethane film, the second layer may comprise a polyurethane foam, and the third layer may comprise an additional polyurethane film.
