Abstract: A reduced pressure treatment apparatus includes a charging chamber storing a first pressure less than an ambient pressure and a regulated chamber storing a second pressure less than the ambient pressure. The first pressure is less than the second pressure. A conduit provides fluid communication between the regulated chamber and the charging chamber. A regulator member is operably associated with the conduit to prevent fluid communication through the conduit when the second pressure is less than or equal to a desired therapy pressure and to allow fluid communication through the conduit when the second pressure exceeds the desired therapy pressure.

Abstract: A reduced pressure delivery system for applying a reduced pressure to a tissue site is provided. The system includes a manifold having a plurality of flow channels. The manifold is configured to be placed adjacent the tissue site. A first conduit is in fluid communication with the flow channels of the manifold to deliver a reduced pressure to the flow channels. A second conduit is in fluid communication with the flow channels of the manifold and is operably connected to a valve. The valve selectively purges the second conduit with ambient air when the valve is positioned in an open position, and a controller is operably connected to the valve to place the valve in the open position for a selected amount of time at a selected interval during delivery of reduced pressure through the first conduit.

Abstract: Described are improvements to the structure and functionality of a reduced pressure adapter used to connect a distribution manifold and a reduced pressure source instrumentation in a reduced pressure wound treatment (RPWT) system. The reduced pressure adapter reduces instances of unintentional liquid ingress into ancillary lumens of a reduced pressure delivery tube, while channeling the liquid to a primary lumen of the reduced pressure delivery tube.

Abstract: A low-profile dressing interface or connector may comprise 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 and the other for sensing negative pressure within the recessed space adjacent the tissue interface. The apparatus may comprise a top layer having a plurality of closed cells with tapered sidewalls. The apparatus may also comprise a base layer forming a sealed space between the top layer and the base layer. The base layer may further include a plurality of closed cells having tapered sidewalls. The apparatus may then further comprise a barrier coupled between the top layer and the base layer to form two fluid pathways within the sealed space.

Abstract: A multi-layer dressing for treating tissue with negative pressure, instillation, or both. In some embodiments a first layer may be formed from reticulated foam having a series of holes. A second layer disposed adjacent to the first layer may be formed from a perforated polymer. The dressing may optionally include a third layer formed from a soft polymer, such as a silicone gel. The third layer may also have perforations or apertures. The third layer is generally oriented to face a tissue site, and may be disposed adjacent to the first layer so that the first layer is disposed between the third layer and the first layer. The perforations or apertures in the third layer may be registered with one or more perforations in the first layer.

Abstract: Methods of debriding a wound include applying a wound debridement material in frictional contact across at least a portion of a wound surface of a patient and removing tissue from the wound surface via adherence of the tissue to the wound debridement material without leaving solid debris of the wound debridement material on the wound surface after the application of the wound debridement material. A wound debridement material comprising a solid porous foam soaked by a fluid suitable for use in such methods is also provided.

Abstract: A dressing for treating a tissue site with negative pressure includes a manifold having a first surface and a second surface opposite the first surface. The dressing also includes a first layer adjacent to the first surface and a second layer adjacent to the second surface. The first layer and the second layer each include a polymer film. The dressing also includes a plurality of fluid restrictions in the polymer film adjacent to at least the first surface, and a plurality of bonds between the first layer and the second layer. The plurality of bonds defines separable sections of the manifold.
