Uses may include treating a traumatic injury such as in injury caused by a bullet, an explosive, a blade etc., or an injury caused during a medical procedure such as surgery.

A method of manufacturing a tissue interface for a reduced pressure tissue treatment system is provided. The method includes foaming a plurality of polymer particles to form a porous polymer. The method also includes sintering the porous polymer to form a sintered porous polymer. The method further includes texturing the sintered porous polymer. A system to provide reduced pressure at a tissue site is provided. The system includes a cover configured to form a seal over the tissue site. The system also includes a reduced-pressure source configured to provide reduced pressure through the cover at the tissue site. The system further includes a tissue interface configured to be disposed underneath the cover at the tissue site and comprising a porous polymer that is formed from one or more polymer particles that may be foamed and textured.

Snap band dressing devices and methods are disclosed. The snap band dressing device serves to protect a point of entry from bacteria and other elements found outside the body. For example, the snap band in dressing devices may include a snap band having an elongated open shape and a coiled closed shape, and a layer integral with or coupled to the snap band and configured to elute a fluid to a wound site when the snap band is positioned around the circumferential wound site in the coiled closed shape. Methods are also provided including snapping a snap band in a coiled closed shape about a circumferential wound site and eluting an antimicrobial substance to a wound site when the snap band is positioned around the circumferential wound site in the coiled closed shape.

Dressings, systems, and methods for treating a tissue site are described. The dressing can include a first layer having a first side and a second side and a plurality of through-holes extending through the first layer from the first side to the second side. The dressing can also include a second layer configured to be positioned adjacent the second side of the first layer. The second layer can have a plurality of fluid restrictions and a plurality of perforations disposed in the second layer. The plurality of perforations can be configured to be aligned with the plurality of through-holes in the first layer.

Negative pressure wound therapy sponges that are custom-fabricated to fit a given wound to be treated, corresponding methods of creating said sponges in situ or external to a wound, and related systems for performing negative pressure wound therapy using said sponges. Exemplary sponge embodiments may have pressure-sensing capabilities.

A method for dressing a wound. The method includes introducing a chromic material via at least one article to the wound and stimulating the chromic material with a stimuli. The method also includes providing a color change in response to stimulating the chromic material and indicating via the color change of the chromic material how long the article has been at least partially in contact with the wound. In one or more embodiments, the method may also include measuring the color change from information including a plurality of colors corresponding to a plurality of time periods and, in response to measuring the color change, determining a length of time the article has been in contact with the wound. The method may also include manually crumpling a distal end of a portion of the article such that the distal end of the portion is sized to be received within the wound and then manually separating the crumpled distal end from the rest of the article.

Negative pressure wound therapy sponges that are custom-fabricated to fit a given wound to be treated, corresponding methods of creating said sponges in situ or external to a wound, and related systems for performing negative pressure wound therapy using said sponges. Exemplary sponge embodiments may have pressure-sensing capabilities.

Systems and apparatuses for administering reduced pressure treatment to a tissue site include a reduced pressure source, a drape having a plurality of projections for contacting the tissue site, and an adhesive connected to at least a portion of the drape for sealing the drape to a portion of a patient's intact epidermis.

A method of manufacturing a reduced-pressure abdominal treatment system for treating an open abdominal cavity is provided. In some embodiments, the reduced-pressure abdominal treatment system has an open-cavity treatment device for providing reduced-pressure treatment to an abdominal cavity; a deep-tissue closure device for applying a closing force on a deep-tissue wound; and a surface-wound closure subsystem for providing a closing force on a surface wound. The method of manufacturing may also include providing a reduced-pressure supply subsystem. A method of treatment using a reduced-pressure abdominal treatment system is also disclosed.

The present invention relates to an adhesive patch. The adhesive patch includes a plurality of reliefs, each relief having a flat top face, and each micro channel groove defined between adjacent reliefs of the plurality of reliefs, wherein the plurality of reliefs and the micro channel groove are respectively formed on and defined the adhesive patch, and wherein a hydrogel layer is disposed on at least a portion of a bottom face of the micro channel groove and is contained in the groove. Therefore, the adhesive patch is well-adhered to a dry or wet adhered face.
