Abstract: Provided herein is a system and method for attaching and detaching elements of a medical fluid collection system. One aspect provides a high-strength canister retention system with automated, non-mechanical canister release. A canister may have a switchable adhesive that can adhere the canister to a medical therapy unit. When detachment of the canister is desired, the switchable adhesive can be deactivated by exposure to certain light wavelengths, particularly UV light, emitted from a light source disposed in the medical therapy unit. This allows for easy detachment of the canister from the medical therapy unit without the use of mechanical latches.

Abstract: A portable therapy system for treating a tissue site, particularly a venous leg ulcer, is disclosed. In some embodiments, the therapy system may include a bridge, a dressing, or both, which contain a material suitable for binding bacteria and/or protein. Such a binding material may be used in conjunction with one or more manifold or wicking layers disposed within the bridge or the dressing to help contain bacteria and/or protein present in fluid extracted from the tissue site, such as wound exudate. By binding the bacteria and/or protein present in wound exudate, particularly wound exudate that may possess a high viscosity due to a greater concentration of proteins, blockages and associated pressure drops across the components of the therapy system may thus be minimized or avoided.

Abstract: Some illustrative embodiments of an instillation assembly for treating a tissue site may include a fluid distribution lumen and a fluid hub that may define a fluid instillation pathway. The fluid distribution lumen may be defined by a first film layer and a second film layer, and the fluid hub may be positioned in fluid communication with the fluid distribution lumen. The instillation assembly may be used in combination with a reduced-pressure assembly that may define a reduced-pressure pathway separate from the fluid instillation pathway.

Abstract: Provided herein is a system and method for mitigating premature light deactivation of light deactivated adhesive drapes. One aspect provides a system comprising a drape, an adhesive layer, and a release agent, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a photochromic layer that may transition between a blocking transmittance state and a non-blocking transmittance state to block or allow certain wavelengths of light to pass through. Some systems may use a combination of a photochromic layer and a filter layer to prevent the adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing one or more of a photochromic layer and a filter layer and applying light to the drape to deactivate the adhesive layer and promote easy, clean, and less painful removal of the drape.

Abstract: A porous conduit may be suitable for use in treating a tissue site, and may include a central lumen and a porous wall positioned substantially concentric about the central lumen. The porous wall may have an open porous structure that may define a plurality of interconnected pores in fluid communication with one another. As part of a system, the porous conduit may be used with a manifold adapted to be positioned at a tissue site, a sealing drape adapted to cover the manifold to provide a sealed space relative to the tissue site, and a therapy device including a reduced-pressure source. The porous conduit may be disposed in the sealed space and in fluid communication between the sealed space and the reduced-pressure source.

Abstract: This disclosure includes wound dressings and systems with high-flow therapeutic gas sources for topical wound therapy and related methods. Some dressings, which are configured to be coupled to tissue to facilitate delivery of therapeutic gas to the tissue, comprise a manifold that defines a plurality of gas passageways, the manifold configured to allow communication of therapeutic gas to the tissue; and a gas-occlusive layer configured to be disposed over the manifold and coupled to the tissue such that an interior volume containing the manifold is defined between the gas-occlusive layer and the tissue and the gas- occlusive layer limits escape of therapeutic gas from the interior volume; wherein the gas- occlusive layer includes: a first opening configured to allow communication of therapeutic gas into the interior volume; and one or more second openings configured to allow communication of therapeutic gas out of the interior volume.

Abstract: A treatment system (100) for debriding an area of a tissue site is disclosed. In some embodiments, the system may include a debridement tool (122) which may be fluidly connected to a negative-pressure source (116) and a fluid source (118). The system may also include a control unit for interfacing with an operator and for regulating the application of negative pressure and delivery of treatment fluid to the debridement tool. The debridement tool may include multiple fluid conduits for delivering and removing fluid to and from the tissue site, as well as a brush (128) for assisting with the removal of necrotic tissue.

Abstract: Microstrain-inducing manifolds, systems, and methods are presented that involve microstrain-inducing manifolds that include a plurality of shaped projections for creating microstrain. The shaped projections may be tapered projections. A system may include a sealing member for placing over the tissue site, a microstrain-inducing manifold, and a reduced-pressure subsystem that delivers reduced pressure to the sealing member. The reduced pressure causes the shaped projections to create microstrain at the tissue site. Other methods, apparatuses, and systems are also presented.

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: In some examples, a dressing suitable for treating a tissue site may include a sealing member having a periphery and a central portion. The central portion of the sealing member may include a breathable zone having a higher vapor permeability than the periphery of the sealing member. Other features may be associated with the dressing including, by way of example and without limitation, a base layer, an adhesive, one or more wicking layers, and an absorbent layer. Other dressings, apparatus, systems, and methods are disclosed.
