Abstract
Absorbable/resorbable mixtures of aliphatic polyesters of poly(lactide), poly(glycolide), poly(trimethylene carbonate), poly(p-dioxanone) and poly(.epsilon.-caprolactone) and calcium containing bone regenerating compounds such as powdered, non-fibrous calcium phosphates are described. The composites when used to manufacture medical devices exhibit improved absorption characteristics and other physical properties.
