Abstract: Systems, methods, and apparatuses for generating and releasing iodine are described. Some embodiments may include a dressing member including a plurality of iodine-forming reagents and a water-swellable material. In some embodiments, the dressing member may include water-swellable fibers. The water-swellable fibers may each include a water-swellable material in which iodine-forming reagents are dispersed. As liquid comes into contact with and is absorbed by the water-swellable material, the iodine-forming reagents may come into contact with each other, causing an iodine-forming reaction to occur, producing iodine.

Abstract: Systems, methods, and dressing are presented for treating a tunnel wound on a patient. In one instance, a reduced-pressure, tunnel-wound dressing includes a longitudinal core member formed from a closed-cell foam that is surrounded by a first longitudinal concentric member formed from a manifolding material. When subjected to reduced pressure, the longitudinal core member expands and the first longitudinal concentric member compresses. These actions create intimate contact between the tunnel wound and the dressing, oppose collapse of the tunnel, and when reduced pressure is removed provide clearance to remove the dressing. Other embodiments are presented.

Abstract: Systems, methods, and apparatus are provided for detecting leaks in systems for treating a patient with reduced pressure. In one instance, a system includes a distribution manifold for disposing proximate to the tissue site and a sealing member for disposing over the distribution manifold and at least a portion of intact epidermis of the patient. The sealing member has at least a portion that is substantially transparent. The system further includes a reduced-pressure source associated with the distribution manifold for providing reduced pressure to the distribution manifold and a leak-detection member sized and configured to substantially surround the distribution manifold. The leak-detection member includes a detection material that develops a color contrast when a portion is exposed to air and a portion is not exposed to air. The leak detection member works with even low flow systems. Other systems, methods, and apparatus are presented.

Abstract: Systems, methods, and devices are presented for treating a tissue site and managing hair proximate the tissue site. A composition is provided for inhibiting, removing, or weakening hair proximate the tissue site and for providing an improved fluid seal by a flexible film drape over the tissue site. In some example embodiments, a hair-modification agent is disposed at least proximate a peripheral edge of a treatment manifold between a drape and epidermis proximate a tissue site. The hair-modification agent can be configured to flow over imperfections on the epidermis and to form a fluid seal against the epidermis, and can further be configured to at least substantially weaken hair on the epidermis as the hair encounters the hair-modification agent.

Abstract: Systems, kits, methods of manufacturing, and a sealing member for creating a sealed space are described. The sealing member can include a film layer and a first adhesive layer coupled to the film layer. The sealing member can also include a second adhesive layer coupled to the first adhesive layer. A plurality of apertures may extend through the second adhesive layer. Each aperture can expose at least a portion of the first adhesive layer through the second adhesive layer. A plurality of polymer particles may be disposed in the first adhesive layer. The polymer particles can be configured to dissolve in response to interaction with a switching solution.

Abstract: A system for treating a tissue site with negative-pressure is described. The system includes a manifold configured to be positioned adjacent to the tissue site and a drape configured to be positioned over the tissue site and the manifold to form a sealed space. The system also includes a negative-pressure source configured to provide negative-pressure to the sealed space. The drape includes a film layer, a layer of a bonding adhesive coupled to the film layer, and a mesh coupled to the layer of the bonding adhesive. The mesh includes a coating of a sealing adhesive and one or more bonding apertures. Methods of manufacturing the drape are also described.

Abstract: Systems and methods for a reduced-pressure interface for providing reduced pressure through a sealing member to a distribution manifold includes a housing having a flange portion and a cavity wall portion such that the cavity wall portion forms a cavity having a tissue-facing cavity opening. A conduit port is coupled to the cavity wall and has a conduit aperture, such that the conduit port is adapted to receive a reduced-pressure delivery conduit. An attachment device is coupled to a tissue-facing side of the flange portion of the housing such that the attachment device couples the housing to the sealing member. Additionally, a cutting element is at least temporarily coupled to the housing proximate to the tissue-facing cavity opening such that the cutting element is adapted to form an aperture in the sealing member when the cutting element is driven into the sealing member with a driving force.

Abstract: A manually-actuated, constant reduced-pressure apparatus for use with a reduced-pressure system for treating tissue at a tissue site includes a flexible, collapsible member that is operable to move between a compressed position and an extended position. The collapsible member may be disposed between a carrier member and a slider member that move between a compressed position and an extended position. The carrier member and slider member are urged away from each other by a constant-force biasing member, e.g., a constant force coil spring. As the apparatus moves from the compressed position to the extended position, a constant reduced-pressure is generated and delivered to a reduced-pressure port. Methods of manufacturing a manually-actuated, constant reduced-pressure apparatus and methods of treating a tissue site are also provided.

Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a plurality of apertures and may be adapted to cover the tissue site. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. A conduit comprised of an absorbent material that is vapor permeable and liquid impermeable may be in fluid communication with the dressing for providing reduced pressure to the dressing. Other dressings, systems, and methods are disclosed.

Abstract: To offload forces from a tissue site being treated with reduced pressure, an offloading pressure component may be used as part of a reduced-pressure treatment system. A reduced-pressure source of the reduced-pressure treatment system vents positive pressure exhaust into the offloading pressure component to inflate the offloading pressure component. The offloading pressure component disperses forces away from the tissue site. Other devices, methods, and systems are presented.
