Described herein are dressings for incision management comprising a dressing layer that comprises: an elastic layer such as a hydrocolloid or foam layer; and an absorbent layer coupled, for example by lamination, to the elastic layer and which comprises: (i) from about 45% to about 90% carboxymethyl cellulose fibers; and (ii) from about 10% to about 55% elastic reinforcing fibers. Though the elastic layer may be substantially elastically deformable under tissue treatment conditions and the absorbent layer may be not elastically deformable under tissue treatment conditions, the coupling together of the elastic layer and the absorbent layer may result in a dressing layer, and advantageously a dressing, that is substantially elastically deformable under tissue treatment conditions. Methods for manufacturing such dressings and of eliminating, minimizing, or reducing edema using such dressings are also described herein.

A wound product and a method of manufacturing the wound product is provided. The wound product comprises a first layer comprising a plurality of splittable fibres. At least some of the plurality of splittable fibres are split longitudinally along at least part of their length, and at least some of the plurality of splittable fibres are entangled.

A wound dressing includes a superabsorbent layer, a backing layer, and a charcoal layer. The superabsorbent layer is configured to absorb wound fluid and has a first side and a second, wound-facing side. The backing layer also has a first side and a second, wound-facing side. The backing layer is substantially impermeable to liquid and substantially permeable to vapor. The charcoal layer is positioned between the first side of the superabsorbent layer and the second, wound-facing side of the backing layer. The charcoal layer is configured to increase a moisture vapor transmission rate of the wound dressing.

A reduced-pressure system for treating tissue, such as damaged subcutaneous tissue, includes a shaped dressing bolster for placing on the patient's epidermis and substantially sized to overlay the damaged subcutaneous tissue. The system further includes a sealing subsystem for providing a fluid seal over the shaped dressing bolster and a portion of the patient's epidermis, and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The reduced-pressure system may develop a force, which may include a vertical force that is realized at tissue site deeper than the epidermis or a closing force directed towards the incision. The shaped dressing bolster is shaped to evenly distribute the force. Other methods and systems are included.

A method of making a wound dressing comprising the steps of: providing an apertured substrate layer; coating the substrate layer with a fluid silicone prepolymer composition; thermally partially curing said silicone prepolymer composition to form a partially cured silicone coating on the substrate; laminating the coated substrate layer to a base layer to form a laminate having said partially cured silicone coating in contact with a surface of the base layer; followed by exposing the laminate to ionizing radiation, to further cure the partially cured silicone coating and to bond the silicone coating to said surface of the base layer. The radiation cure results in strong bonding between the siliconized substrate and incompatible base layers such as polyurethane foams. Also provided are wound dressings obtainable by the process of the invention.

A modular transdermal drug delivery system is provided, the system including: an upper module in which an outer backing layer is laminated to a pressure-sensitive adhesive layer that is covered by a removable release liner prior to assembly; and a lower module with a porous drug reservoir layer laminated to a skin-contact adhesive that affixes the system to the skin during drug delivery, where the skin-contact adhesive is, in one embodiment, an adhesive layer that is substantially co-extensive with the porous drug reservoir layer and, prior to use, protected with a second removable release liner. Methods of manufacture and use are also provided, as is an assembled transdermal drug delivery system fabricated by affixing the pressure-sensitive adhesive layer of the upper module to the porous drug reservoir layer of the lower module.

The present invention relates to a composition that can be used as or as part of a wound dressing and to wound dressings comprising the same. More specifically, the present invention relates to a composition that disrupts and kills bacteria within a biofilm and also prevents biofilm formation. The composition comprises a fibrous first component selected from the group consisting of chitosan, chitin, derivatives of chitosan, derivatives of chitin, and combinations thereof; at least one triprotic acid and at least one solubilising acid.

Systems, methods, and apparatuses for treating a tissue site are described. In some embodiments, the system may include a pouch having an upstream layer, a downstream layer, and an absorbent member enclosed between the upstream layer and the downstream layer. The upstream layer and the downstream layer may each include a hydrophobic side and a hydrophilic side. The hydrophilic side of both the upstream layer and the downstream layer may be positioned facing the absorbent member. The hydrophobic side of both the upstream layer and the downstream layer may form a portion of an exterior surface of the pouch such that fluid incident on the pouch is distributed laterally along the exterior surface of the pouch before being absorbed by the absorbent member.

A composite material is described, which is of particular use in wound treatment, and to a method for producing said composite material is also described. The composite material has a first foam layer having a first hydrophilic polyurethane foam material, and, in immediate contact therewith, a second foam layer having a second hydrophilic polyurethane foam material, which second hydrophilic foam material is different from the first hydrophilic foam material.

In some illustrative examples, a bridge suitable for treating a tissue site may include a bridge sealing member and one or more bridge wicking layers. The bridge sealing member may extend along a length of the bridge, and may define an internal passageway in fluid communication between a receiving end of the bridge and a transmitting end of the bridge. The one or more bridge wicking layers may be disposed within the internal passageway of the bridge sealing member. Other apparatus, systems, and methods are disclosed.
