Abstract: A conduit for treating a tissue site with reduced pressure may include a primary lumen and at least one secondary lumen. A wall of the conduit may include a first wall material and a second wall material. The first wall material may comprise a substantially non-absorbent material that is vapor impermeable and liquid impermeable. The second wall material may comprise an absorbent material that is vapor permeable and liquid impermeable. The second wall material may be positioned in fluid contact with the at least one secondary lumen. Other systems, apparatus, and methods are disclosed.

Abstract: A system that may be adapted to distribute reduced pressure to a tissue site may include a dressing and a sealing member. The dressing may include a manifold layer, a storage layer, and a plurality of retainers. The manifold layer may be adapted to be positioned proximate the tissue site, and the storage layer may be positioned proximate the manifold layer. The plurality of retainers may be disposed in the storage layer. Each of the retainers may define a fluid communication channel through the storage layer. The retainers may be adapted to substantially preclude deformation of the storage layer into the fluid communication channels. The sealing member may be adapted to cover the dressing and to provide a fluid seal between the sealing member and the tissue site.

Abstract: Systems, methods, and apparatuses for providing instillation therapy with a negative-pressure source are described. The apparatus can include a housing having a dosing chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus can also include a moveable barrier disposed in the housing between the dosing chamber and the negative-pressure chamber. The housing includes a fluid inlet in fluid communication with the dosing chamber and a fluid outlet in fluid communication with the dosing chamber. The housing can also include a negative-pressure inlet in fluid communication with the negative-pressure chamber and a biasing element coupled to the moveable barrier. The biasing element is operable to move the moveable barrier between a charge position and a discharge position.
