COPOLYMER OF EPSILON-CAPROLACTONE, GLYCOLIDE AND GLYCOLIC ACID FOR COVERING SUTURE YARN

摘要

PURPOSE: To provide a filament surgical suture having a high biological absorptivity by coating the suture with a copolymer ofε-caplactone, glycolide and glycol acid which has been dissolved in an organic solvent. CONSTITUTION:ε-caplactone having a quantity occupying a major part, the remainder of a glycolide and glycole acid are copolymerlized so as to obtain a copolymer having a glycol acid concentration so that the inherent viscosity of the copolymer is about 0.15 to 0.60 deciliters per gram within hexafluoroisopropyl-aldehyde. A surgical suture is coated with a solution in which this organic solvent is dissolved.
