Biocompatible wound dressing
First Claim
1. A biocompatible wound dressing, comprising:
- a biocompatible pad shaped to conform to a wound site;
an air-tight seal removably adhered to said pad;
a negative pressure source in fluid communication with said pad;
a scaffold removably connected to a wound-contacting surface of the pad, the scaffold being adapted to facilitate cellular growth from the wound into the scaffold.

Abstract
A biocompatible wound dressing comprised of a pad for insertion substantially into a wound site and a wound drape for sealing enclosure of the foam pad at the wound site. The pad, comprised of a foam or other like material having relatively few open cells in contact with the areas upon which cell growth is to be encouraged so as to avoid unwanted adhesions, but having sufficiently numerous open cells so that drainage and negative pressure therapy may continue unimpaired, is placed in fluid communication with a vacuum source for promotion of fluid drainage, as known in the art. The pad is further comprised of an ultra-low density fused-fibrous ceramic, or a bioabsorbable branched polymer, or cell growth enhancing matrix or scaffolding.

8. A biocompatible wound dressing comprising:
-
a first pad comprised of a bioabsorbable or includable cell-growth enhancing matrix, shaped to conform to a wound site; the bioabsorbable or includable cell-growth enhancing matrix comprising porous, highly reticulated material, the matrix being adapted to contact the wound surface and to be absorbed or included by the wound; a negative pressure source in fluid communication with said pad; a second pad comprised of a bioabsorbable or includable cell-growth enhancing matrix, adapted to connect to the surface of the first pad opposite the wound-facing surface and to cover the first pad when the first pad is partially absorbed or included by the wound; and the bioabsorbable or includable cell-growth enhancing matrix of the second pad comprising porous, highly reticulated material, the matrix being adapted to contact the wound surface and to be absorbed or included by the wound; wherein the matrix of the second pad is adapted to facilitate cellular growth from the wound through the matrix; wherein the matrix of the first pad is adapted to facilitate cellular growth from the wound through the matrix. - View Dependent Claims (9, 10)

11. A biocompatible wound dressing comprising:
-
a pad comprised of a non-bioabsorbable substrate, and a bioabsorbable or includable cell-growth enhancing matrix removably coupled to the non-bioabsorbable substrate, the pad being shaped to conform to a wound site; the cell-growth enhancing matrix comprising reticulated porous material formed into a plurality of sections and implanted into the substrate in the central portion of the pad, the matrix being adapted to contact the wound surface and to be absorbed or included by the wound; the substrate defining a plurality of holes remote from the bioabsorbable or includable cell-growth enhancing matrix; and wherein the pad is adapted to be fluidly connected to a negative pressure source. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A biocompatible wound dressing comprising:
-
a bioabsorbable or includable matrix having a surface adapted to be placed in contact with a tissue site at which new cell growth is desired, the bioabsorbable or includable matrix having an invadable space to facilitate cellular growth from the tissue site into the bioabsorbable or includable matrix; a non-bioabsorbable porous substrate removably connected to the matrix; and a flexible tube in fluid communication with at least one of the matrix and the substrate, the flexible tube further being adapted to be fluidly connected to a negative pressure source. - View Dependent Claims (19, 20, 21, 22, 23)
