Synthetic sutures made of polyester fibers, a nonabsorbable (i.e., nonbiodegradable) polymer. These sutures are typically available in sterile monofilament or multifilament thread sections (e.g., 18, 30 inches/45, 76 cm long) attached to a single-use needle as an integral device; they are frequently colored for easy identification during surgery. Polyester sutures keep their tensile strength for very long periods of time and are not absorbed by tissues; their intended use includes general soft-tissue approximation and placement of prosthetic devices.
