Abstract
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 includes 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.
