Abstract: Systems, apparatuses, and methods for providing negative pressure to a tissue site are disclosed. Illustrative embodiments may include an apparatus or system for delivering negative-pressure to a tissue site, which can be used in conjunction with low-profile distribution components for wound therapy. Such apparatus may include a low-profile dressing interface or connector comprising at least two side-by-side fluid pathways fluidly coupled to a recessed space of the connector, one for providing negative pressure to a tissue interface or manifold and the other for sensing the negative pressure within the recessed space adjacent the tissue interface. In some embodiments, for example, the apparatus may comprise a first layer of polymeric film having an outer surface, an inner surface, and a plurality of features extending from the inner surface, and a second layer of polymeric film coupled to the first layer. The second layer may have an outer, tissue-facing surface and an inner surface coupled to the first layer and covering the plurality of features to form an enclosed space with the inner surface of the first layer and a plurality of flow channels within the enclosed space. The second layer also includes an aperture defining the recessed space adapted to fluidly coupling the enclosed space to the tissue interface.

Abstract: A treatment system for applying negative pressure therapy and fluid instillation treatment to a tissue site, particularly an abdominal tissue site, is disclosed. In some embodiments, the treatment system may include a dressing member, a plurality of fluid removal pathways, a fluid instillation matrix, a drape, a negative-pressure source, and a fluid instillation source. Instillation fluid may be delivered from the fluid instillation source to the tissue site through the fluid instillation matrix, and negative pressure may be communicated and fluid withdrawn from the tissue site through the plurality of fluid removal pathways.

Abstract: A system for providing instillation fluid to a deep abdominal wound includes an instillation module and a connection structure. The instillation module defines a first surface and a second, abdominal contents-facing surface. The instillation module includes a distribution hub configured to receive instillation fluid from an instillation fluid source. The connection structure includes a first surface, a second, abdominal contents-facing surface; and a flow path extending between the first surface and the second surface. The flow path includes an inlet configured to receive an instillation fluid conduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module. The flow path defines an axis extending between the inlet and the outlet. The flow path is configured to compress in a direction defined by the axis.

Abstract: A fluid management bridge for providing a fluid communication between a wound interface dressing and a negative pressure source is disclosed. The fluid management bridge comprises a first end having a first fluid port configured to be coupled to a port of the wound interface dressing and a second end having a second fluid port configured to be coupled to the negative pressure device. The first end of the fluid management bridge is configured to provide for central alignment of the first end with the port of the wound interface dressing.

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.
