Abstract
A composition of an absorbable polymer and a filler to increase the stiffness of the polymer is disclosed. The filler is a poly[succinimide], which is a bioabsorbable polymer that degrades into a nontoxic, simple amino acid. The composition can be melt processed to prepare medical and surgical devices, particularly those devices which are designed to penetrate bodily tissue or to withstand heavy loads. Typical surgical devices which can be made from the composition include surgical staples and ligating clips.
