Abstract
A method and apparatus for the introduction to a wound under negative 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 vacuum 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.
Claims5
A method for promoting wound healing in mammals, said method comprising:
- grafting wound healing factors into a porous pad of a negative pressure system, wherein said negative pressure system comprises:
- the porous pad which is permeable to fluids and adapted for positioning within a sealable space defined in part by a wound surface;
- and
- a tube having a first end in fluid communication with said porous pad and a second end in fluid communication with a vacuum source, said vacuum source being adapted to apply negative pressure to said porous pad through said tube.
