Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. At least one of the apertures in the periphery may be positioned at an edge of the periphery, and may have an interior exposed at the edge. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. Other dressings, systems, and methods are disclosed.

Abstract: Systems, kits, methods of manufacturing, and a sealing member for creating a sealed space are described. The sealing member can include a film layer and a first adhesive layer coupled to the film layer. The sealing member can also include a second adhesive layer coupled to the first adhesive layer. A plurality of apertures may extend through the second adhesive layer. Each aperture can expose at least a portion of the first adhesive layer through the second adhesive layer. A plurality of polymer particles may be disposed in the first adhesive layer. The polymer particles can be configured to dissolve in response to interaction with a switching solution.

Abstract: A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.

Abstract: A method and apparatus for disrupting material at a tissue site is described. A contact layer may be selected for use on the tissue site and positioned adjacent to the tissue site. The contact layer may include walls defining a plurality of through-holes. A sealing member may be positioned over the contact layer and sealed to tissue surrounding the tissue site to form a sealed space enclosing the contact layer. A negative-pressure source may be fluidly coupled to the sealed space. The negative-pressure source may supply negative pressure to the sealed space and the contact layer to draw tissue into the through-holes to form nodules. The negative pressure may be vented from the sealed space to release the nodules.

Abstract: Systems, apparatuses, and methods for closing an opening through a surface of a tissue site are described. The system includes a sealing member adapted to cover the opening to form a sealed space and a negative-pressure source adapted to be fluidly coupled to the sealed space to provide negative pressure to the sealed space. The system also includes a contracting layer adapted to be positioned adjacent the opening and formed from a material having a firmness factor and a plurality of holes extending through the contracting layer to form a void space. The holes have a perforation shape factor and a strut angle causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. The contracting layer generates a closing force substantially parallel to the surface of the tissue site to close the opening in response to application of the negative pressure.

Abstract: Inline storage pouches and systems for receiving and retaining body fluids from an animal are presented. The inline storage pouch include a flexible pouch body has an interior portion with a fluid storage material disposed within the interior portion. In addition to receiving body fluids, the inline storage pouch may fluidly couple a pressure sensing conduit between a first port and a second port using a first bypass conduit. The first port may be a patient-port interface. The second port may be a device-port interface. Multiple sensors and bypass conduits may be included and associated with a microprocessor that is configured to locate blockages or determine when the inline storage pouch is full. Another inline storage pouch has two chambers and receives and discharges fluids from a pouch connector. Other pouches, systems, and methods are presented herein.

Abstract: In one example embodiment, an apparatus may include a panel with integrated fluid channels, wherein the panel and the fluid channel consist only of surfaces that can be manufactured with a straight-pull mold. A port may also be integrated into the panel to facilitate coupling the fluid channel to pneumatic components in an assembly. A seal may be secured to the panel over the fluid channel to form an integrated fluid conductor. The seal is preferably an adhesive label that can also be used for product labeling. Such an apparatus may be used in a control unit of a therapy system, employing several integrated fluid conductors. A method of manufacturing may include molding a panel, wherein the mold forms a channel integral to the panel. The panel and the channel preferably consist of surfaces that can be molded with a straight-pull mold.

Abstract: Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure interface includes a conduit housing having a cavity divided by a dividing wall into a reduced-pressure-application region and a pressure-detection region. The reduced-pressure interface further includes a reduced-pressure port disposed within the reduced-pressure-application region, a pressure-detection port disposed within the pressure-detection region, and a base connected to the conduit housing, the base having a manifold-contacting surface. The dividing wall includes a surface substantially coplanar with the manifold-contacting surface.
