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:
Taper Point needles feature a smooth, round cross-sectional profile in the body which narrows to a pointed tip. Taper point needles are indicated for use in all soft tissues with the exception of skin. Tapercutting needles can be used for cutaneous application however.
