Abstract: Methods, dressings, and systems for promoting epithelialization of a wound or other tissue are presented. The methods, dressings, and systems help form simulated rete pegs. In one instance, an epithelialization dressing is disclosed that may include a dressing body having a plurality of projections. A plurality of apertures is formed on a portion of the dressing body. The dressing helps manage fluids on the wound and the projections form cavities into which epithelial tissue migrates to from epithelial columns that function like rete pegs. Other dressings, methods, and systems are disclosed.

Abstract: Systems, methods, and apparatuses are provided for delivering reduced pressure to a subcutaneous tissue site, such as a bone tissue site. In one instance, a manifold for providing reduced pressure to a subcutaneous tissue includes a longitudinal manifold body formed with at least one purging lumen and a reduced-pressure lumen. The manifold further includes a plurality of manifolding surface features or slits formed on the second, tissue-facing side of the longitudinal manifold body and a plurality of apertures formed in the longitudinal manifold body on the second, tissue-facing side. The plurality of apertures fluidly couple the reduced-pressure lumen and the manifolding surface features or slits. The manifold further includes an end cap fluidly coupling the reduced-pressure lumen and the at least one purging lumen. Other systems, apparatuses, and methods are presented.

Abstract: The illustrative embodiments described herein are directed to systems, methods, and apparatuses for applying a reduced pressure to a subcutaneous tissue site. In one instance, a manifold for applying reduced pressure to a subcutaneous tissue site includes a plurality of first conduits, each of the plurality of first conduits having a wall with at least one first aperture and at least one second aperture. At least one of the plurality of first conduits is operable to deliver reduced pressure to the subcutaneous tissue site. The plurality of first conduits is coupled in a spaced arrangement that forms an interior space. The manifold further includes a second conduit comprising the interior space and formed by a portion of each wall of the plurality of first conduits. The second conduit is in fluid communication with the plurality of first conduits via the at least one second aperture.

Abstract: Example embodiments of an apparatus for tissue therapy may comprise a sequentially-collapsing tissue interface for use with negative pressure. More generally, some embodiments may include a first manifold and a second manifold fluidly coupled to the first manifold through a constricted fluid path. A fluid conductor may fluidly couple the second manifold to the first manifold in some embodiments. The fluid conductor may constrict fluid flow between the first manifold and the second manifold. The apparatus may additionally comprise a negative-pressure source fluidly coupled to the first manifold in some embodiments. A controller may be configured to operate a negative-pressure source to provide negative pressure to a tissue interface in a therapy sequence adapted to propagate a wave in the tissue site. Such motion may be particularly advantageous or beneficial for a variety of conditions, including lymphedema, edema, or venous insufficiency.

Abstract: Systems, methods, and apparatuses arc presented that involve forming patterns on neo-epithelium that allow increased functionality and may more nearly resemble the original epithelium. In one instance, a patterned neo-epithelium dressing for treating a tissue site having granulation tissue includes an interface member for placing proximate the granulation tissue and a plurality of three-dimensional features formed on a second, patient-facing side of the interface member. Other systems, methods, and apparatuses are disclosed.

Abstract: An apparatus, system, and method for treating an incisional wound having incisional walls is disclosed. The apparatus includes a conduit having a first end for receiving reduced pressure and a second end. The apparatus further includes a scaffold. The scaffold has opposing surfaces for positioning adjacent the incisional walls and is fluidly coupled to the second end of the conduit for receiving the reduced pressure. The scaffold is generally elongated in shape and has a thickness between the opposing surfaces that is sufficiently thin for positioning within the incisional wound. The apparatus further includes an internal manifold that has a primary flow channel extending generally longitudinally within the scaffold and between the opposing surfaces of the scaffold. The internal manifold is fluidly coupled to the second end of the conduit. The application of the reduced pressure through the scaffold and the internal manifold induces tissue apposition between the incisional walls.
