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 bioabsorbalbe branched polymer , or cell growth enhancing matrix or scaffolding .
