Disclosed herein are apparatuses and methods for treating, a wound by applying reduced or negative pressure to the wound. The apparatus can include a wound cover, a fluid collection container, a vacuum pump, an inflation pump, and one or more conduits. The wound cover can be configured to move between at least a relatively rigid, generally raised position and a relatively flexible, generally collapsed position according to a predetermined program or in response to input from a user or one or more sensors. In some embodiments, the wound cover can be configured to move between at least the relatively rigid, generally raised position and the relatively flexible, generally collapsed position by adjusting the air pressure in one or more channels in the wound cover or by adjusting the length of piezoelectric or other length changing material supported by the wound cover.

A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.

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 plurality of apertures and may be adapted to cover the tissue site. 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. A conduit comprised of an absorbent material that is vapor permeable and liquid impermeable may be in fluid communication with the dressing for providing reduced pressure to the dressing. Other dressings, systems, and methods are disclosed.

A therapeutic compress assembly, system, and method for treating an area of a user is disclosed herein. The therapeutic compress assembly includes an elastic fabric compress and an absorbent pad. The elastic fabric compress is stretchable in a length direction and a width direction. The absorbent pad is coupled to a first side of the elastic fabric compress. The absorbent pad may be impregnated with a medication or an oil. In use, the therapeutic compress assembly is applied to the area of the user.

Wound dressings and wound inserts comprising substantially dry reactive agents, methods of forming wound inserts comprising dry reactive agents, and wound-treatment methods.

The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.

Described are wound pads for use, e.g., as cavity wound fillers, having shapes with rounded corners, the projection on an X-Y plane of at least one corner having a curvature distinct from that of the projection of the other corners. Negative pressure systems and kits that includes such wound pads, and methods of using such wound pads are also described.

Occlusive tissue dressings and methods including an elastomeric drape and a liquid component, at least partially cross-linked at least after one of drying and curing, suitable for application at a dressing-to-skin interface in order to create a substantially air-tight seal. The same or a different liquid component may be applied by a user at a tube-to-dressing interface in order to create a similar air-tight seal around the tube, if not occlusively sealed during its manufacture.

A negative pressure wound therapy system treats multiple wounds on a patient's body. The system includes a source of negative air pressure, an air source, first and second fluid collection volumes, first and second wound-covering domes disposed over first and second wounds, a valve assembly disposed between the source of negative air pressure and the first and second fluid collection volumes, and between the air source and the first and second domes. The valve assembly has first and second operational modes. In the first, the valve assembly puts the source of negative air pressure in fluid communication with the first fluid collection volume, and the air source in fluid communication with the first dome. In the second, the valve assembly puts the source of negative air pressure in fluid communication with the second fluid collection volume, and the air source in fluid communication with the second dome.
