    Abstract: Systems and methods for a reduced-pressure interface for connecting a multi-lumen conduit to a distribution manifold. The interface includes a housing having a flange portion and a cavity wall portion. The cavity wall portion forms a cavity having a tissue-facing cavity opening. The interface further includes an attachment device, a conduit port, and a multi-lumen conduit. The attachment device is coupled to a tissue-facing side of the flange portion for coupling the housing to a sealing member. The conduit includes a distal end and a proximal whereby the distal end extends through a conduit aperture and past the cavity wall portion into the cavity. The conduit further includes a primary lumen and a plurality of sensing lumens. The primary lumen and the plurality of sensing lumens extend from the proximal end of the conduit to the distal end. The conduit is adapted to contact the distribution manifold.

    Abstract: Described herein are dressings comprising a composite island comprising a polyurethane or foam layer coupled to an absorbent layer comprising non-woven gelling fibers. Also described herein are dressings comprising an absorbent layer comprising carboxymethyl cellulose fibers and a backing layer coupled to the absorbent layer. In the respective dressings, the absorbent layer is not elastically deformable under tissue treatment conditions, whereas the polyurethane or foam layer and the backing layer are substantially elastically deformable under tissue treatment conditions. The coupling of the absorbent layer to the polyurethane/foam layer or backing layer renders the coupled structure or the entire dressing substantially elastically deformable under tissue treatment conditions. Methods of eliminating, minimizing, or reducing edema are also described herein.

    Abstract: Disclosed herein are devices, systems and methods for delivering reduced pressure to a load-bearing wound site. The device can include a distal port configured to connect to a wound dressing positioned over the wound site; a proximal port located a distance from the distal port and configured to connect to a reduced pressure source, and a conduit body having an inner channel extending between the distal port and the proximal port. When the distal port is applied to the wound dressing positioned over the wound site the proximal port is positioned at a non-load bearing location remote from the wound dressing. The inner channel has a non-circular profile having a width larger than a height of the conduit body.

    Abstract: A modular wound therapy training device, system, and method of use for the device are provided. The device may include a support tray, an elastic insert, a base within the elastic insert, a recess within the base, a conformable polymer, a dressing and a negative pressure source. The recess may be circumferentially smaller than the base and the conformable polymer may be sized to fit within the recess. The device is preferably sized and shaped to form a system when aligned and assembled with duplicates of the device. A method is provided to apply negative pressure and installation therapy when a negative pressure source is activated through a protective dressing.

    Abstract: A wound treatment system comprises a wound-treatment apparatus and a wound dressing coupled to the apparatus. The wound dressing includes a foam structure wound insert having pores with a greater cross-sectional area when viewed from a first direction and a smaller cross-sectional area when viewed from an orthogonal direction. Methods for making such wound inserts may include compressing foam structure material having pores with a substantially uniform cross-sectional area. Methods for treating a wound using a wound insert.

    Abstract: A negative pressure wound therapy system includes at least one sensor coupled to a wound dressing for a wound of a patient, and a processing circuit. The at least one sensor is configured to output a measurement of the pressure in the wound dressing. The processing circuit is configured to open a sealable aperture, receive the pressure measurements in the wound dressing, calculate a rate of pressure decay, correlate the rate of pressure decay in the wound dressing to a wound dressing fluid absorbent capacity and other therapy parameters, and output the wound dressing fluid absorbent capacity and other therapy parameters to a remote electronic device.
