A method, and apparatus for the controlled acceleration, and/or retardation of the body's inflammatory response generally comprises a foam pad for insertion substantially into a wound site, a heating, a cooling pad for application over the wound site, a wound drape or sealing enclosure of the foam pad, the heating, and cooling pad at wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of the controlled acceleration or retardation of the body's inflammatory response. The heating, and cooling provision controls the local metabolic function as part of the inflammatory response.

Negative pressure treatment system with heating and cooling provision

An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a healing manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material enclosed by sheets of elastomeric material punctuated by a number of appropriately placed holes. Multiple layers of porous foam may also be used. A suction tube connector is provided on an upper surface of a layer of foam for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope and through the foam.

Abdominal wound dressing

An apparatus and method for the controlled acceleration, and/or retardation of the body's inflammatory response comprises a foam pad for insertion into a wound site, a drape covering the foam pad, and a thermal control element configured to be placed proximate the wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of the controlled acceleration or retardation of the body's inflammatory response. The thermal control element has a pair of flexible sheets for receiving a thermally conductive fluid.

An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a healing manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The method comprises providing a flexible film having a plurality of holes therein and placing the flexible film in the wound. The flexible film has a first, patient-facing side and a second side. The method includes placing a porous pad on top of the second side of the flexible film. The flexible film and porous pad are sealed within the wound with a drape that is positioned in contact with an area of skin surrounding the wound. A negative pressure is provided to the porous pad for drawing a flow of exuded fluids from the wound.

A system and method for the temporary closure of a wound, especially an abdominal wound, to facilitate re-entry, final closure, and long term healing of the wound. An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a site healing promoting manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material () enclosed by sheets of elastomeric material () punctuated by a number of appropriately placed holes (). Multiple layers of porous foam may also be used. A suction tube connector () is provided on an upper surface of a layer of foam () for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope, and through the foam. If multiple foam layers are employed, the lower layer(s) of foam are of a finer porosity while the upper layer of foam is coarse. An adhesive elastomeric sheet () covers the entire wound dressing and seals the edges to the skin surrounding the wound. An appropriate vacuum device is attached to the suction tube connector.

Removable wound closure

A method, and apparatus () for the controlled acceleration, and/or retardation of the body's inflammatory response generally comprises a foam pad () for insertion substantially into a wound site, a heating, a cooling pad () for application over the wound site (), a wound drape () or sealing enclosure of the foam pad (), the heating, and cooling pad () at wound site (). The foam pad () is placed in fluid communication with a vacuum source for promotion of the controlled acceleration or retardation of the body's inflammatory response. The heating, and cooling provision controls the local metabolic function as part of the inflammatory response.
