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 (36) enclosed by sheets of
elastomeric material (38) punctuated by a number of appropriately placed
holes (34). Multiple layers of porous foam may also be used. A suction
tube connector (16) is provided on an upper surface of a layer of foam
(12) 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 (14) 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.
