Abstract: A super-absorbent dressing assembly for use with a reduced-pressure wound treatment system includes a breathable, fluid restricted dry layer for placement against a wound, a super-absorbent layer, and a non-breathable layer, and a drape extending over the non-breathable layer. A reduced-pressure interface is available to fluidly couple the super-absorbent layer to a reduced-pressure subsystem. The super-absorbent dressing assembly preferably supplies a compressive force when placed under reduced pressure. A reduced-pressure treatment system uses a super-absorbent bolster to treat wounds, e.g., linear wounds.

Abstract: Some embodiments of a manifold pad may be configured to distribute reduced pressure relative to a tissue site and to provide a lateral contractive force relative to the tissue site. In some embodiments, the manifold pad may comprise a foam having a cell-structure forming ovoidal or ellipsoidal pores. In some embodiments, the manifold pad may be configured to preferentially contract radially or laterally upon application of negative pressure. For example, the manifold pad may be configured to be more resistant to collapse of the thickness of the manifold pad than to collapse radially or laterally. Other apparatus, dressings, systems, and methods are disclosed.

Abstract: Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

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.

Abstract: Disclosed embodiments may relate to dressings configured to provide negative-pressure wound therapy to a tissue site, while simultaneously shielding a portion of the tissue site from the negative pressure. For example, dressing assembly embodiments may comprise an outer dressing configured for applying negative-pressure wound therapy to a tissue site, and an underlying isolation patch configured for use under the outer dressing. The isolation patch may be configured to seal the portion of the tissue site so that it does not experience the negative pressure. Additionally disclosed are other apparatus, dressings, systems, and methods.

Abstract: A dressing for a wound includes a drape, an absorbent core, and a wicking member. The drape can be configured to sealingly couple with a patient's skin surrounding the wound. The drape may enclose an inner volume of the dressing. The absorbent core layer may be positioned within the inner volume of the dressing. The wicking member is positioned within the inner volume, wherein the wicking member extends from an underside of the absorbent core layer to the drape. The indicator may be configured to fluidly couple with the wicking member through the drape and receive fluid from the wicking member. The indicator may be configured to provide a visual wound status indication in response to receiving fluid from the wound through the wicking member.

Abstract: A moisture trap for removing liquid from a fluid drawn from a tissue site treated with reduced pressure and systems and methods for using the same are described. The moisture trap may include a barrier adapted to be fluidly coupled to and define an indirect fluid path between a fluid reservoir and a reduced-pressure source. The barrier may have a hydrophilic surface. The moisture trap also may include a sump adapted to receive condensation from the barrier.

Abstract: This disclosure includes wound dressings and systems with high-flow therapeutic gas sources for topical wound therapy and related methods. Some dressings, which are configured to be coupled to tissue to facilitate delivery of therapeutic gas to the tissue, comprise a manifold that defines a plurality of gas passageways, the manifold configured to allow communication of therapeutic gas to the tissue; and a gas-occlusive layer configured to be disposed over the manifold and coupled to the tissue such that an interior volume containing the manifold is defined between the gas-occlusive layer and the tissue and the gas-occlusive layer limits escape of therapeutic gas from the interior volume; wherein the gas-occlusive layer includes: a first opening configured to allow communication of therapeutic gas into the interior volume; and one or more second openings configured to allow communication of therapeutic gas out of the interior volume.
