Abstract: A system for treating a tissue site with negative-pressure is described. The system includes a manifold configured to be positioned adjacent to the tissue site and a drape configured to be positioned over the tissue site and the manifold to form a sealed space. The system also includes a negative-pressure source configured to provide negative-pressure to the sealed space. The drape includes a film layer, a layer of a bonding adhesive coupled to the film layer, and a mesh coupled to the layer of the bonding adhesive. The mesh includes a coating of a sealing adhesive and one or more bonding apertures. Methods of manufacturing the drape are also described.

Abstract: Reduced-pressure sources, systems, and methods involve using a vacuum pump that is disposed within a sealed space to produce reduced pressure. The exhaust from the vacuum pump is exhausted from the sealed space through pores in an enclosure member that is made of a polymeric, porous, hydrophobic material. Other devices, systems, and methods are disclosed.

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: Illustrative embodiments of a dressing for treating a tissue site may include a fluid transport layer, an offloading layer, and a liquid deflector. The offloading layer may be in fluid communication with the fluid transport layer, and the offloading layer may include a force offloading region and a target region. The liquid deflector may be positioned between the fluid transport layer and the offloading layer. The liquid deflector may be configured to deflect a liquid from the tissue site into contact with the target region of the offloading layer. The target region may be configured to expand for offloading forces at the tissue site. Other dressings, systems, and methods are disclosed.

Abstract: Systems, assemblies, and methods for providing negative-pressure therapy to a tissue site are described. The system can include an absorbent and a sealing layer configured to cover the absorbent. The system can also include a blister fluidly coupled to the absorbent. The blister may have a collapsed position and an expanded position. A first check valve may be fluidly coupled to the absorbent and the blister and configured to prevent fluid flow from the blister into the absorbent if the blister is moved from the expanded position to the collapsed position. A second check valve may be fluidly coupled to the blister and the ambient environment and configured to prevent fluid flow from the ambient environment into the blister if the blister is moved from the collapsed position to the expanded position.

Abstract: A wound-closing dressing, which is suitable for use as part of a reduced-pressure, wound-treatment system, may include a sealing drape, one or more contracting elements, and a gripping member. The contracting element may be coupled to the sealing drape and is configured to contract when activated and to generate a closing force. A gripping member is coupled to the sealing drape and is configured to transmit the closing force to a patient's epidermis. Other dressings, systems, and methods are also disclosed.

Abstract: An open-cavity, reduced-pressure treatment device and system for treating a cavity in a patient's body, such as an abdominal cavity, is presented. In one instance, an open-cavity, reduced-pressure treatment device includes a plurality of encapsulated leg members, each having an interior portion with a leg manifold member and formed with fenestrations operable to allow fluid flow into the interior portion, and a central connection member fluidly coupled to the plurality of encapsulated leg members. The central connection member has a connection manifold member. The open-cavity, reduced-pressure treatment devices, systems, and methods allow for, among other things, removal of fluids.

Abstract: Dressings for closing an opening through a surface of a tissue site are described. The dressing includes a cover adapted to form a sealed space over the opening and a bolster. The bolster is adapted to be positioned adjacent the opening and includes a first plurality of holes. The holes have an average width to length ratio causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. Systems, apparatuses, kits and methods including and/or using the dressing for closing the opening are also described.

Abstract: A system for treating a tissue site includes a reduced-pressure source to apply reduced pressure, a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site, and a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape includes an adhesive layer for sealing the drape to the tissue site to create a sealed space having the manifold therein, and a non-adhesive layer formed from a portion of the adhesive layer. A method for manufacturing a medical drape includes providing a sheet of adhesive material and treating a side of the sheet of adhesive material to form a non-adhesive layer and an adhesive layer. The method laminates a release liner adjacent the adhesive layer.

Abstract: A system and method for performing tissue therapy may include applying a reduced pressure to a tissue site, sensing a fluid parameter being applied to the tissue site, generating a fluid sensor signal in response to sensing the fluid parameter, and altering the fluid sensor signal in response to sensing that the fluid parameter changes. A fluid leak location mode may be entered. In response to the fluid leak location mode being entered, a graphical user interface that provides for fluid leak location functionality may be displayed. In one embodiment, the fluid leak location mode may be automatically entered in response to the sensor signal crossing a threshold value. Additionally, an alarm signal may be generated in response to determining that the fluid sensor signal crosses the threshold value.
