Abstract

A surgical suture material of absorbable, synthetic polymer is formed from glycolide-trimethylene carbonate copolymer with a glycolide content higher than 76 wt. % and with a statistical distribution of the monomers. Within 9 to 21 days, the suture material has a complete breaking strength loss and is completely absorbed in vivo after 35 to 91 days.
