The braided, non-absorbable silk suture can generally be used for:

• Tissue suturing
• Retention in contact
• Soft tissue approximation

Its use is not indicated for the tissues of the central cardiovascular and central nervous system.

The application of the non-absorbable surgical suture S initially causes a slight inflammatory reaction of the tissues, characteristic of the reaction to a foreign body, followed by the gradual formation of a connective tissue capsule around the suture.

Silk sutures are not absorbed, but the proteins are progressively degraded with a gradual loss of their tensile strength.
