Biocompatible wound dressing
First Claim
1. A biocompatible wound dressing comprising:
- a pad comprising an open-cell porous foam adapted to be in fluid communication with a vacuum source for delivering a negative pressure to the pad; and
a material implanted in the pad in fluid communication with the pad, the material having a surface adapted to be placed in contact with a tissue site where new cell growth is desired and having an invadable space for cellular growth from the tissue site into the invadable space, wherein the invadable space of the material remains in place following treatment.

Abstract
A biocompatible wound dressing comprised of a pad for insertion substantially into a wound site and 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.

13. A method of promoting new cell growth at a wound site comprising:
-
positioning a scaffold in contact with the wound site; delivering a negative pressure to the wound site through the scaffold to induce new cell growth from the wound site into the scaffold; and allowing the scaffold to remain in place at the wound site after delivery of negative pressure to promote new cell growth. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
