    Abstract: Systems, methods, and connectors are provided that introduce a working gas at certain times into a reduced-pressure dressing into order to break or avoid vacuum locks in the conduits removing fluids. In one instance, a reduced-pressure connector includes a connector body for applying a reduced pressure to the tissue site. The connector body is formed with a venting port, a body conduit, and a receptacle to receive a reduced-pressure delivery conduit. The reduced-pressure connector includes a flexible member coupled to the connector body over the venting port. The flexible member is formed with at least one venting aperture. The flexible member is biased away from the venting port and is configured to collapse and seal the venting port under a reduced pressure greater than a threshold pressure. Other systems, apparatuses, and methods are disclosed.

    Abstract: Systems and apparatuses for administering reduced pressure treatment to a tissue site including a wound filler for positioning adjacent a wound site on a patient. The wound filler includes at least one strand having a plurality of nodes positioned along a length of the strand. The at least one strand has a charged state and an uncharged state. In the charged state, the at least one strand includes a stored energy that when released would deform or move the at least one strand. In the discharged state, the stored energy has been released. The wound filler further includes a removable sheath encasing the at least one strand. The at least one strand transitions from the charged state to the uncharged state as the removable sheath is removed.

    Abstract: A negative pressure wound treatment (NPWT) system including a NWPT therapy unit and a wound dressing configured to overlay a wound bed. The NPWT system includes a first length of tubing comprising a first end and a second end, the first end of the first length of tubing coupled to the NWPT therapy unit and the second end of the first length of tubing having a first coupling half, as well as a second length of tubing having a first end and second end, the first end of the second length of tubing coupled to the wound dressing and the second end of the second length of tubing having a second coupling half. The NPWT system includes an inline filter comprising a sintered polymer and a superabsorbent material, and an inline coupling, wherein the inline coupling is configured to operably couple and de-couple the NPWT therapy unit and wound dressing.

    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 dressing for treating a tissue site, particularly a peritoneal or abdominal site, is disclosed. The dressing may comprise: a substrate; an adherent layer coupled to a surface of the substrate; and a fibrous layer comprising fibers coupled to a surface of the adherent layer opposite the substrate. Typically, the fibrous layer satisfies one or more of the following: at least 75% of the fibers are coupled approximately perpendicular to the surface of the substrate; at least 95% of the fibers in the fibrous layer have a length to diameter aspect ratio from about 10 to about 1000; and no more than 10% of the fibers are coupled approximately tangential to the surface of the substrate. Optionally, the fibrous layer may be formed by a flocking process. Methods of treating various tissue sites using the dressings and negative-pressure therapy are also disclosed.

    Abstract: Systems, assemblies, and methods for providing negative-pressure therapy to a tissue site are described. The system can include an absorbent and a sealing layer configured to cover the absorbent. The system can also include a blister fluidly coupled to the absorbent. The blister may have a collapsed position and an expanded position. A first check valve may be fluidly coupled to the absorbent and the blister and configured to prevent fluid flow from the blister into the absorbent if the blister is moved from the expanded position to the collapsed position. A second check valve may be fluidly coupled to the blister and the ambient environment and configured to prevent fluid flow from the ambient environment into the blister if the blister is moved from the collapsed position to the expanded position.
