BIOSYN™ synthetic absorbable sutures are prepared from a synthetic polyester, GLYCOMER 631, composed of glycolide (60%), dioxanone (14%) and trimethylene carbonate (26%). The advanced 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™ synthetic absorbable 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.
