Violet Dyed Coated Vicryl (polyglactin 910) Sutures from Ethicon Inc. Coated Vicryl Suture is a synthetic absorbable sterile surgical suture composed of a copolymer made from 90% glycolide and 10% L-lactide. Coated VICRYL Suture has a tensile strength that is greater than gut and knot security that will last longer than gut by a few weeks. Coated VICRYL is said to absorb completely in 56 - 90 days. Violet dyed Vicryl is more visible, which is ideal for situations where you want to make sure the suture can be seen more clearly.
