Biosyn™ synthetic absorbable sutures are prepared from Glycomer™ 631, a synthetic polyester composed of glycolide (60%), dioxanone (14%) and trimethylene carbonate (26%). These sutures are colored violet to increase visibility and are also available undyed. The advance extrusion process of the molecule of Glycomer™ 631 gives the suture:
Excellent initial strength
Excellent in vivo strength over the critical wound healing period
Excellent knot security
Minimal memory for handling ease
Biosyn™ sutures are indicated for use in general soft tissue approximation and/or ligation including use in ophthalmic surgery, but not for use in cardiovascular or neurological surgery.
