Patent ID: 8158729

Claim:
A process for producing a bioabsorbable material, the method comprising: polymerizing lactide monomers and ε-caprolactone monomers simultaneously under a three-dimensionally shaped metal zinc polymerization catalyst to provide a bioabsorbable material; and removing the three-dimensionally shaped metal zinc polymerization catalyst from the bioabsorbable material by using a physical force, wherein the three-dimensionally shaped metal zinc polymerization catalyst has a shape selected from the group consisting of a wire-like shape, a rod-like shape, a plate-like shape, a ball-like shape, a net-like shape, and a mesh-like shape, wherein the lactide is at least one selected from the group consisting of L, L-lactide, D, D-lactide, and D, L-lactide, and wherein the physical force is a force to peel-off or cut-off the three-dimensionally shaped metal zinc polymerization catalyst.
