Indications for Use
REXLON is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures, but not for use in cardiovascular or neural tissue. REXSIL is indicated for use in general soft tissue approximation and/or ligation, including use in ophthalmic procedures, but not for use in cardiovascular or neural tissue.
Device Story
REXLON and REXSIL are sterile, nonabsorbable surgical sutures used for soft tissue approximation and ligation. REXLON is a monofilament polyamide (Nylon 6 and 6,6); REXSIL is a braided silk suture (fibroin protein from Bombyx mori) coated with silicone. Both are available with or without stainless steel (STS 304) needles. Used by clinicians in surgical settings. Sutures provide mechanical tissue closure; performance verified against USP standards for diameter, tensile strength, and needle attachment. Biocompatibility confirmed per ISO 10993. Sterilized via ethylene oxide. Benefits include secure tissue approximation and visibility (dyed black/blue or natural).
Clinical Evidence
Bench testing only. No clinical data. Testing included USP 35 <861> (diameter), <871> (needle attachment), <881> (tensile strength), <71> (sterility), <85> (bacterial endotoxin), and <151> (pyrogen). Biocompatibility testing performed per ISO 10993-1, -3, -4, -5, -6, -7, -10, and -11. Shelf life supported by real-time and accelerated aging studies.
Technological Characteristics
REXLON: Monofilament polyamide (Nylon 6/6,6). REXSIL: Braided silk (fibroin) with silicone coating. Needles: Stainless steel STS 304. Sterilization: Ethylene oxide (ISO 11135-1). Compliance: USP 35 <861>, <871>, <881>. Biocompatibility: ISO 10993. Packaging: ASTM F88-09 (seal strength), ASTM F1929-98 (leak detection).
