Although the name "Vicryl" is a trademark of Ethicon, the term "vicryl" has been used generically referring to any synthetic absorbable suture made primarily of polyglycolic acid. Other brands of polyglycolic acid suture include Surgicryl, Polysorb and Dexon, all of which are manufactured by different companies. Vicrylis a copolymer of lactide (a cyclic diester of lactic acid) and glycoside. In practice, vicryl comes as braided, dyed or undyed with the following decay schedule: 75% at 2 weeks, 50% at 3 weeks, and 25% at 4 weeks.

Needle Curvature
Straight Needles: This needle should be used when tissue is easily accessible, and is designed to be used by hand (without the aid of instruments). The straight needles are most useful for skin closure or microsurgical procedures like nerve and vessel repair.

Half-curved (ski): This needle is used to suture using laparoscopic technique. It is rarely used in rodent surgery.

1/4 Circle: This needle has a shallow curvature and is used on easily accessible convex surfaces. Typically used for ophthalmic and microsurgical procedures.

3/8 Circle: This is the most commonly used needle. The curvature makes it easy to manipulate in large and superficial wounds, however it is impossible to use in deep cavities due to the large arc of manipulation needed.

1/2 Circle: This needle is to be used in confined locations, but requires more pronation and supination of wrists.

5/8 Circle: This needle is ideal for deep, confined holes, and can be used by rotating the wrist with little to no lateral movement.

Types of non-absorbable suture are silk, stainless steel, polyester, polypropylene, nylon, and cotton. These, like absorbable sutures come in differing gauges, depending on the level of tension needed to close the defect. The smaller the gauge that is used, the less the tissue reaction will be and the faster the wound will heal.
Suture Size
There are two classifications of suture size; those that follow USP (United States Pharmacopeia) or those that follow the European system. The European system uses the diameter of the suture in millimeters. The USP method uses a complex relationship between diameter, tensile strength, and knot security.
