Polysorb™ sutures are composed of Lactomer™ glycolide/lactide copolymer, which is a synthetic polyester composed of glycolide and lactide (derived from glycolic and lactic acids). They are prepared by coating the suture with a mixture of a caprolactone/glycolide copolymer and calcium stearoyl lactylate. The sutures are colored violet to increase visibility and are also available undyed.
The advanced extrusion process of the molecule of Lactomer™ 9-1, the exclusive braiding process and coating system, give the suture:
Polysorb™ sutures are indicated for use in soft tissue approximation or ligation and ophthalmic surgery, but not in cardiovascular or neural tissue.
