| 摘要 |
The present invention is based, in part, on studies we conducted with biocompatible compositions that contain a copolymer and a filler material. Accordingly, the invention features compositions that include a copolymer (e.g., a copolymer that includes lactic acid and/or glycolic acid monomers) and a filler such as calcium carbonate (e.g., about 30-40% CaCO<SUB>3 </SUB>by weight (i.e., by weight of the composition as a whole)).
