Abstract: Disclosed embodiments relate to devices and systems for providing both negative-pressure therapy and instillation, In some embodiments, both negative-pressure and instillation may be provided to a tissue site in a low-profile context that may also prevent siphoning of instillation fluid during negative pressure application. For example, a single bridge may include a negative-pressure pathway with supports and an instillation pathway, and the instillation pathway may be configured with respect to the negative-pressure pathway so that at least a portion of the instillation pathway collapses upon application of negative pressure to the negative-pressure pathway. Collapse of at least a portion of the instillation pathway may be sufficient to close the instillation pathway.

Abstract: An apparatus for promoting circulation through a subcutaneous lymph vascular network may comprise a first manifold layer, a second manifold layer coupled to the first manifold layer, and a cover layer coupled to the second manifold layer. The first manifold may have a first stiffness, and the second manifold may have a second stiffness greater than the first stiffness. In some embodiments, the apparatus may additionally have a fluid interface configured to fluidly couple at least one of the first manifold layer and the second manifold layer to a fluid conductor through the cover layer. The fluid conductor may be coupled to or configured to be coupled to a source of negative pressure.

Abstract: An evaporative bridge dressing that may be used with negative-pressure treatment of tissue. The evaporative bridge dressing may have one or more fluid transfer layers comprised of high-density wicking material enclosed between layers of film having high moisture-vapor transfer rates to reduce liquid storage and minimize pressure drop.

Abstract: New and useful systems, apparatuses, and methods for providing negative-pressure therapy with instillation of topical treatment solutions are described. An apparatus may comprise an exudate container, a solution source, and a pneumatically-actuated instillation regulator. The instillation regulator may be coupled to the exudate container and to the solution source, and negative pressure from a negative-pressure source can actuate the instillation regulator. In some embodiments, a negative-pressure source may be configured for a negative-pressure interval and a venting interval, and the instillation regulator can be configured to draw instillation solution from the solution source during a negative-pressure interval and to instill the solution to a dressing during a venting interval.

Abstract: Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described. Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. A pneumatic actuator may be mechanically coupled to a disposable distribution system that can provide a fluid path between the solution source and a distribution component. A bacterial filter may be disposed in the fluid path between the actuator and the distribution component to prevent contamination of the actuator during operation. The distribution system may be separated from the actuator and disposed of after operation, and the actuator may be re-used.

Abstract: 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.
