BIOABSORBABLE MEDICAL DEVICES FROM OXIDIZED POLYSACCHARIDES

摘要

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