Abstract: A reduced pressure tissue treatment system includes an applicator having an aperture, a first pad section, and a second pad section substantially covering the aperture and positioned substantially adjacent the first pad section. A fabric layer is located at least partially between the second pad section and the drape, and the fabric layer includes a woven or non-woven fabric made from a fiber material. A drape substantially covers the first pad section, the second pad section, the fabric layer, and the applicator. A reduced pressure source is in fluid communication with at least one of the first pad section and the fabric layer for providing reduced pressure to the aperture.

Abstract: A dressing for treating a tissue site with negative pressure includes a manifold having a first surface and a second surface opposite the first surface. The dressing also includes a first layer adjacent to the first surface and a second layer adjacent to the second surface. The first layer and the second layer each include a polymer film. The dressing also includes a plurality of fluid restrictions in the polymer film adjacent to at least the first surface, and a plurality of bonds between the first layer and the second layer. The plurality of bonds defines separable sections of the manifold.

Abstract: Systems, methods, and devices related to removing fluids from a patient are provided. In one instance, fluid is removed from the patient and delivered to a canister using reduced pressure. Reduced pressure is supplied to the canister via a reduced-pressure delivery conduit that includes a moisture processing device and a hydrophobic filter. The moisture processing device condenses moisture from the air to prevent condensation from occluding the hydrophobic filter. The moisture processing devices includes an expanded volume and one or more liquid-impermeable, vapor-permeable membranes. The liquid-impermeable, vapor-permeable membrane allows vapor to egress the moisture processing device. Other systems, methods, and devices are presented.

Abstract: A sealing system that includes a switchable drape is presented. The drape provides enhanced sealing by using a high-strength adhesive. In one instance, the switchable drape has a plurality of perforations through which a switching solution may be delivered to the high-strength adhesive. The switching solution causes the high-strength adhesive to become less adhesive so that the switchable drape may be removed more easily. Other systems, methods, and drapes are presented.

Abstract: Body-fluid containers, methods, and systems are presented that include a container that has a container housing formed, at least in part, by a liquid-impermeable, vapor-permeable material. The liquid-impermeable, vapor-permeable material allows water to evaporate and be transmitted outside of the container. The evaporation allows more fluid to be processed by the container than the container could otherwise hold. Other systems, methods, and apparatuses are presented.

Abstract: A treatment system for applying negative-pressure therapy to a wound site is disclosed. The treatment system may include a non-adherent material for applying to the perimeter of the wound site. In some embodiments, the treatment system may include a tape, a tissue interface, a sealing member, and a negative-pressure subsystem. The tape material may provide a smooth surface along the perimeter of the wound site for protecting the wound edges from stresses and for promoting epithelialization.

Abstract: Dressings for use in negative pressure therapy and methods of making the dressings are provided herein. The dressings may comprise at least two layers in a stacked configuration. The first layer may comprise a manifold layer and the second layer may comprise a silicone gel layer. The second layer may have perforations to form fluid restrictions that can open and close when used in negative pressure therapy. The perforated second layer may be formed by a first and a second curing step.

Abstract: A reduced pressure treatment apparatus includes a charging chamber storing a first pressure less than an ambient pressure and a regulated chamber storing a second pressure less than the ambient pressure. The first pressure is less than the second pressure. A conduit provides fluid communication between the regulated chamber and the charging chamber. A regulator member is operably associated with the conduit to prevent fluid communication through the conduit when the second pressure is less than or equal to a desired therapy pressure and to allow fluid communication through the conduit when the second pressure exceeds the desired therapy pressure.

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.
