Synthetic sutures made of polyvinylidene fluoride homopolymer and polyvinylidene fluoride hexafluoropropylene copolymer, nonabsorbable (i.e., nonbiodegradable) polymers. The sutures are typically available in sterile monofilament uncoated thread sections (e.g., 18, 30 in [45, 76] cm long) attached to a single-use needle as an integral device; they are frequently colored for easy identification during surgery. These synthetic nonabsorbable sutures keep their tensile strength longer than seven years and are not absorbed by tissues; their intended use includes vascular and/or cardiovascular procedures when fine sutures are needed.
