Abstract: A method for uniformly coating a foam or dressing with a polymer-based or metal-based coating incorporating at least one therapeutic or prophylactic agent and a foam or dressing formed by this process. Such foam or dressing is particularly useful in combination with subatmospheric pressure tissue treatment, wherein the foam or dressing formed by the process serves as at least a portion of a screen placed in contact with the tissue and enclosed under a cover. During application of a subatmospheric pressure within the space defined by the cover, the screen compresses and conforms to the tissue, increasing an area of contact between the screen and the tissue. The coating releases the agent directly to the area of contacted tissue. In embodiments where the agent is silver, the coating releases silver ions directly to the contacted tissue to reduce bacterial density thereon.

Abstract: A method and apparatus for the introduction to a wound under subatmospheric pressure therapy of a wound healing agent, generally comprises a foam pad (11) for insertion substantially into a wound site (12), and a wound drape (13) for sealing enclosure of the foam pad at the wound site. The foam pad is placed in fluid communication with a subatmospheric pressure source for promotion of fluid drainage. Additionally, the foam pad is predisposed, through grafting or other techniques known to those of ordinary skill in the art, with basic fibroblast growth factor (bFGF), anti-microbial or other factors, also known to those of ordinary skill in the art, for the promotion of increased wound healing.

Abstract: A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A first hydrophobic filter is positioned at an opening of the canister to detect a canister full condition. A second hydrophobic filter is positioned between the first filter and the negative pressure source to prevent contamination of the non-disposable portion of the system by exudates being drawn from the wound. An odor filter is positioned between the between the first and second hydrophobic filters to aid in the reduction of malodorous vapors.

Abstract: A wound therapy device comprising a head and a surgical drape. The head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The second face is formed with projections that define flow channels for facilitating flow of liquids to and from the aperture.

Abstract: The present invention provides skin grafting and devices that comprise a systematic approach to the process of skin grafting, i.e., harvesting, post-excision processing and application of donor skin and pre and post-graft treatment of the recipient site.

Abstract: A wound treatment dressing for applying negative pressure wound therapy to a wound of an extremity, such as on the heel of a foot. The dressing comprises a fluid manifold 14 positioned within a fenestrated drape 16 to form a contoured occlusive wrapping 10 for placement over a wound on an extremity. A contoured porous pad 26 is placed adjacent or within the wound, such that the contoured pad 26 is enveloped by the occlusive wrapping 10. Flexible tubing 42 is attached to or through a fluid communication port 18, which forms an opening to the outer layer 16b of the occlusive wrapping 10, so as to allow for fluid communication of negative pressure to the contoured pad 26 from a source of negative pressure 44 connected to an opposite end of the flexible tubing 42. The negative gauge pressure is communicated from the source 44, through the tube 42, through the fenestrations 19 of the occlusive wrapping 10, such that negative gauge pressure is applied to the wound on the extremity.
