Abstract: A negative pressure wound therapy (NPWT) device for a deep abdominal wound. The compressive component includes a body having a first compressive profile. The body includes a plurality of removable portions of the material. The plurality of removable portions are configured to be selectively removed to form a pattern of voids to transform the first compressive profile of the body into a second compressive profile of the body based on the pattern of voids. The pattern of voids includes at least one void.

Abstract: A partially transparent dressing includes a fluid management core having a first side and a second, wound-facing side. The fluid management core includes an absorbent material and a plurality of optically transparent windows. The dressing includes a barrier layer coupled to the first side and a patient interface layer coupled to the second side. A fluid communication port is disposed in the second side. An opening is disposed in the patient interface layer. The opening is configured to receive fluid from a wound.

Abstract: A wound debridement system includes a wound dressing having an active layer (40) and a wound interface layer (10). The active layer is formed from one or more pneumatic members (45). The pneumatic members are arranged about a film layer (60), by which the pneumatic members are attached to the wound interface layer. A control unit (80) controls a drive unit (70) to intermittently apply pressure to the pneumatic members of the active layer. The pressure applied by the drive unit causes the pneumatic members to expand and contract. This movement of the pneumatic members is transferred to the wound interface layer, causing the wound interface layer to move relative to a tissue site to which the wound dressing is applied. The wound interface layer may be formed having an abrasive wound-facing surface, such that the movement of the wound interface layer causes a mechanical disruption and debridement of debris at the tissue site.

Abstract: A canister for a wound therapy includes a canister body and a plurality of superabsorbent projections. The canister body is configured to contain wound exudate collected from a wound side. The plurality of superabsorbent projections are fixed to and extend from at least a portion of an interior surface of the canister, and may be formed in a plurality of shapes or patterns comprising circles, squares, hoops/halos, a range of lines, or any combination of said shapes.
