Biosyn monofilament absorbable sutures have the tensile strength needed for the critical wound healing period of about three weeks. Biosyn synthetic sutures are prepared from Gylcomer 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. Biosyn sutures are indicated for use in general soft tissue approximation, subcuticular skin closure and/or ligation including use in ophthalmic surgery. The advanced extrusion process of the molecule of Gylcomer 631 gives the suture:
Reverse & Premium Reverse Cutting (Also Called Cosmetic Revrse Cutting = CRC) Reverse cutting needles feature tri-coined, reverse cutting edges for use in dense connective tissue and skin. The cutting edge is on the convex surface of the needle arc, facilitating needle passage while minimizing tissue cut-through. Premium reverse cutting needles are made exclusively of Surgalloy material for added strength and ductility.
