Abstract: Systems, methods, and apparatuses for increasing liquid absorption are described. Some embodiments may include a dressing having an absorbent layer containing super-absorbent material as well as ionic-exchange media (IEM). In some embodiments, the absorbent layer may include absorbent fibers. The absorbent fibers may each include a super-absorbent core surrounded by a water-permeable layer onto which ionic-exchange media (IEM) may be grafted. As liquid comes into contact with the IEM, its ionic nature may be reduced, therefore protecting the absorbent qualities of the super-absorbent material.

Abstract: Systems, apparatuses, and methods for utilizing a dressing having a single manifold fluidly coupled to at least two therapy units in a negative-pressure therapy and/or instillation therapy environment as set forth herein. In one example embodiment wherein the therapy system comprises two therapy units, apparatus and methods may be utilized for alternately applying pressure or fluids to a single tissue site to more quickly remove large amounts of fluid from the tissue site.

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: Methods, apparatuses, and systems for promoting re-epithelialization as an aspect of wound healing are presented. A re-epithelialization dressing for use with reduced pressure has a moist tissue-interface layer, a manifold member, and a sealing member. The moist tissue-interface layer has a plurality of apertures. The moist tissue-interface layer is for disposing adjacent to the wound and provides a moisture balance (i.e., provides moisture when the wound is dry and receives moisture when the wound site is substantially wet). The reduced pressure, apertures, and moist tissue-interface layer help with liquid management and otherwise promote re-epithelialization. Other systems, apparatuses, and methods are presented.

Abstract: Skin graft harvesting systems and methods are disclosed that utilize sensors to automate the harvesting of skin grafts or assist a user in deciding when the skin graft is ready to be harvested. Such systems and methods can reduce the burden of visual observation and ensure greater reliability and consistency of the grafts. The invention is particularly useful with harvesters that rely upon suction and/or heating to raise a plurality of small or “micro” blisters simultaneously.

Abstract: A system for applying negative pressure to a joint positioned in a treatment area. The system includes a negative pressure dressing. The negative pressure dressing includes a compressive layer and a sealing layer. The compressive layer includes a first surface and a second, treatment area-facing. The compressive layer further includes a first elongated portion configured to be positioned proximate the joint. The first elongated portion includes a first end and a second end. The compressive layer further includes a second elongated portion spaced from the first elongated portion and configured to be positioned proximate the joint. The second elongated portion includes a first end and a second end. The compressive layer further includes an interconnecting portion extending between the first elongated portion and the second elongated portion. The interconnecting portion is configured to overlie at least a portion of the joint. The compressive layer further includes a plurality of channels formed in the first surface and extending proximate the second surface. The plurality of channels is formed in at least one of the first end and the second end of the first elongated portion and at least one of the first end and the second end of the second elongated portion. The sealing layer is configured to form a seal around a perimeter of the negative pressure dressing.

Abstract: A system, method, and apparatus for treating a tissue site with reduced pressure includes a dressing adapted to be positioned proximate the tissue site. An absorbent may be adapted to be fluidly coupled to the manifold, and an ion exchange member may be adapted to be fluidly coupled between the manifold and the absorbent. A sealing member may be adapted to cover the tissue site to form a sealed space having the manifold disposed therein. A reduced-pressure source may be adapted to be fluidly coupled to the manifold.
