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source to the tissue site through the fluid instillation matrix, and negative pressure may be communicated and fluid withdrawn from the tissue site through the plurality of fluid removal pathways.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: Dressings, systems, and methods are disclosed that, in some embodiments, relate to treating a tissue site. In one embodiment, a dressing may include a manifold, a retention pouch, a sealing member, and a conduit interface. The manifold may be adapted to distribute reduced pressure to the tissue site, and the retention pouch may be adapted to retain and manage fluid extracted from the tissue site. The sealing member may cover the retention pouch and the manifold to provide a sealed space with the tissue site. The conduit interface may be in fluid communication with the sealed space and an exterior surface of the sealing member. The dressing may be utilized with a therapy device operable to control reduced pressure in the dressing and fluid flow over the sealing member.

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: Systems, methods, and apparatuses for providing feedback for reduced-pressure treatment of a tissue site are described. A regulator may include a supply chamber fluidly coupled to the dressing, a control chamber fluidly coupled to the dressing, a charging chamber fluidly coupled to the supply chamber through a port, and a regulator valve operable to control fluid communication through the port based on a pressure differential between the control chamber and a therapy pressure. The feedback system may include one or more mechanical feedback interfaces fluidly coupled to the regulator to provide a signal of at least one of an application of reduced-pressure therapy, a leak condition, a blockage condition, and a canister full condition.

Abstract: Disclosed embodiments relate to devices and systems for providing negative-pressure therapy, instillation, and/or pressure-sensing at a tissue site, and to methods of manufacturing such devices and systems. In some embodiments, a fluid bridge may comprise a first layer of foam with a plurality of supports extending from at least an inner surface, and a second layer. The first and second layers may be coupled together around the perimeter to form one or more enclosed fluid pathways, for example extending from a port to an aperture. In some embodiments, at least the first layer may be formed of closed-cell foam.

Abstract: An apparatus for filling a wound can include an array of at least four truncated ellipsoids interconnected to define at least one fluid path through, for example perpendicular to, the array. The longest principal axis of each ellipsoid may be perpendicular to the array. Each truncated ellipsoid may be a spheroid and/or may include an approximately elliptical contact surface at each contact surface between two interconnected ellipsoids. Each fluid pathway may have four continuously-curved concave sides and may have a parallelogram-shaped cross-section with continuously-curved concave edges. A dressing may include the apparatus, a dressing layer coupled to the apparatus, a backing layer disposed over a surface of the dressing layer opposite the apparatus, and an attachment device disposed on at least a margin of the backing layer. Methods of treating various tissue sites using the apparatus or dressing with negative-pressure therapy are also disclosed.

Abstract: One implementation of the present disclosure is a negative pressure wound therapy (NPWT) system, according to some embodiments. In some embodiments, the system includes an instillation system configured to provide instillation fluid to a wound site, and a controller. In some embodiments, the wound site includes a wound and a wound dressing. In some embodiments, the controller is configured to provide a first quantity of instillation fluid for a first instillation cycle. In some embodiments, the controller is configured to determine a second quantity of instillation fluid for a second instillation cycle based on the first quantity and a reduction factor. In some embodiments, the second quantity of instillation fluid is less than the first quantity of instillation fluid. In some embodiments, the controller is configured to adjust an operation of the instillation system to provide the second quantity of instillation fluid to the wound site.

Abstract: A negative-pressure source is described. The negative-pressure includes a first housing and a second housing configured to be coupled to the first housing to form a cavity. The first housing and the second housing are rotatable on a common axis relative to each other. A membrane is disposed in the cavity and sealed to the second housing to form a first chamber and a second chamber. A motor is disposed in the first chamber, and a clockwork is coupled to the motor and configured to be driven by the motor. A threaded body is disposed in the first chamber and configured to be driven by the motor. The threaded body is configured to rotate on the common axis and to displace the membrane in response to rotation on the common axis.
