An improved adhesion-preventative physical barrier, wound dressing and drug delivery system comprising an oxidized cellulose film made up of multiple layers of a cellulose fabric or like material and a cellulose film. A method for forming an improved oxidized cellulose film and for using the same to prevent the formation of postsurgical adhesions and/or to dress a wound and/or to deliver one or more drugs.

Bioabsorbable medical devices are prepared by oxidizing derivatives of cellulose, including methyl cellulose, carboxymethylcellulose, and cellulose acetate. The resulting material is formed into films, sponges and, in the case of oxidized methyl cellulose, gels, due to its unique property of being water soluble. The resulting devices are particularly useful in limiting surgical adhesions, and for hemostasis. Other uses include wound dressings and as a replacement for more expensive bioabsorbable gels such as hyaluronic acid.
