Suture Material

 

Sutures are designed to help the body heal by closely opposing two sides of a wound to minimize scar formation or to prevent leaking blood, like in vessels. Sutures have to comply with several regulations and guidelines such as United States Pharmacopeia and the FDA to ensure they meet the necessary requirements.

 

Essential suture characteristics:

All sutures by DemeTech are manufactured to meet the necessary qualities:

 

    • Sterility

    • Uniform diameter and size

    • Pliability for ease of handling and knot security

    • Uniform tensile strength by suture type and size

    • Freedom from irritants or impurities that would elicit tissue reaction

 

 

United States Pharmacopeia

 

The United States Pharmacopeia classification system was established in 1937 for standardization and comparison of suture materials, corresponding to metric measures. The 3 classes of sutures are collagen, synthetic absorbable, and nonabsorbable. Size refers to the diameter of the suture strand and is denoted as zeroes. The more zeroes characterizing a suture size, the smaller the resultant strand diameter (eg, 4-0 is larger than 5-0). The smaller the suture, the less tensile strength of the strand.

 

 

 

Natural Suture Materials

 

Natural sutures are made from natural materials such as collagen derived from the gastrointestinal track of animals, woven cotton, raw silk, linen, or steel. Because of the material, tissue reaction is often greater with natural sutures, especially those that are absorbable (e.g. Catgut). Coating agents are often used to help reduce tissue reactivity and to help reduce friction.

SUTURE INFORMATION

Class I - Silk or synthetic fibers of monofilament, twisted,

                or braided construction.

Class II - Cotton or linen fibers or coated natural or synthetic

                  fibers in which the coating contributes to suture

                  thickness without  adding strength.

Class III - Metal wire of monofilament or multifilament construction

Synthetic sutures are made from synthetic collagen derived from polymers.
