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.
