Abstract
A process for making an adsorbable, annealed surgical device of a multi-phase, polymeric composition derived from lactide and glycolide. The process includes the preparation of a first polymer having predominantly lactide moieties, followed by the intimate mixing of particles of a second polymer containing a predominant amount of glycolide moieties, thereby forming a two-phase polymeric composition. The polymeric composition is then formed into a surgical device and annealed.
