Abstract
Abstract A moldable biodegradable surgical material is made of a bioabsorbable polymer derived from hydroxyacids, lactones, carbonates, etheresters, anhydrides, orthoesters and copolymers, terpolymers and/or blends thereof, the polymer blended with at least one surface active agent selected from the group consisting of fatty acid ester and poly(oxypropylene)/poly(oxyethylene) block copolymer. In one embodiment, a leaching agent is blended with the above-mentioned surgical material. Methods of making moldable biodegradable surgical material are provided. The surgical material may be used as a moldable bone wax in connection with repair of wounds and is an adaptable aid for any appropriate surgical use, e.g., hemostat, anchor, patch etc.
