Stainless steel sutures are composed of 316L stainless steel conforming to ASTM Standard F138 Grade 2 “Stainless steel bar and wire for surgical implants”.
Steel sutures are the most inert among all suture materials and provide maximum tensile strength.
They are indicated for use in abdominal wound closure, intestinal anastomosis, hernia repair, sternal closure and also for certain orthopedic procedures (cerclage or tendon repair).
