Abstract: A system suitable for treating a tissue site may include an interface manifold, an interface sealing member, an absorbent layer, and a storage sealing member. The interface manifold may be positioned in fluid communication at the tissue site. The interface sealing member may be adapted to provide a sealed treatment space relative to the tissue site, and the interface manifold may be positioned in the sealed treatment space. The absorbent layer may be for positioning on an exterior facing side of the interface sealing member. The storage sealing member may be adapted to provide a sealed storage space between the storage sealing member and the exterior facing side of the interface sealing member. The absorbent layer may be positioned in the sealed storage space. Other systems, apparatuses, and methods are disclosed.

Abstract: Systems, methods, and dressings for treating a linear wound, such as an incision, on a patient are presented. The systems, dressings, and methods include a sealing ring that helps form a fluid seal around the linear wound. In one instance, a sealing material is extruded around the linear wound to help form a seal. In another instance, a sealing ring is coupled to a lower portion of a dressing bolster to form a seal. Other systems, methods, and apparatuses are disclosed.

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: 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: Adjustable covers, systems, and methods are presented that include an adjustable cover that may be adjusted to an appropriate size by hand without requiring cutting tools and without substantial leaks. In one instance, the adjustable covering includes a drape member with a plurality of non-leaking tear paths. Each non-leaking tear path includes a weakened path of the drape member that may be torn. The adjustable covering may further include a first plurality of tear starters formed on a first initiation edge of the drape member. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path. The grains of the drape member, a backing layer, and support layer may also be in the same direction. Other adjustable covers, systems, and methods are presented.

Abstract: Systems, methods, and apparatuses for debriding a tissue site are described. The system includes a manifold and a cover adapted to form a sealed space over the tissue site for providing negative pressure. The system also includes a debridement tool positioned between the manifold and the tissue site. The debridement tool having a tissue-facing surface and a plurality of holes separated from each other by walls. The walls have transverse surfaces extending between the tissue-facing surface and an opposite surface that form cutting edges. The holes have a perforation shape factor that allows the holes to collapse from a relaxed position to a contracted position in response to the application and removal of negative pressure from the sealed space. The cutting edges debride the tissue site in response to movement between the relaxed position and the contracted position.

Abstract: Systems, methods, and dressing are presented for treating a tunnel wound on a patient. In one instance, a reduced-pressure, tunnel-wound dressing includes a longitudinal core member formed from a closed-cell foam that is surrounded by a first longitudinal concentric member formed from a manifolding material. When subjected to reduced pressure, the longitudinal core member expands and the first longitudinal concentric member compresses. These actions create intimate contact between the tunnel wound and the dressing, oppose collapse of the tunnel, and when reduced pressure is removed provide clearance to remove the dressing. Other embodiments are presented.

Abstract: Provided are systems, dressings, and methods suitable for treating a tissue site, such as an incision or linear wound. The systems, dressings, and methods relate to a dressing assembly that may include a dressing bolster and a sealing ring. The sealing ring may be adapted to provide a fluid seal around the tissue site, and to absorb fluids from the tissue site. In some embodiments, the sealing ring may be extruded around the tissue site. In other embodiments, the sealing ring may be coupled to the dressing bolster. Other systems, apparatuses, and methods are disclosed.

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: A reduced pressure dressing for applying reduced pressure treatment to a tissue site includes an interface layer adapted to be positioned at the tissue site. An absorbent layer is in fluid communication with the interface layer to absorb liquid from at least one of the interface layer and the tissue site. A pump is in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site. A cover is positioned over the pump, the absorbent layer, and the interface layer to maintain the reduced pressure at the tissue site, and a liquid-air separator is positioned between the absorbent layer and the pump to inhibit liquid from entering the pump.
