Flexor® Kink-Resistant Ureteral Access Sheath System | Model FUS-120045 | Sizing: 12 French Inner Diameter x 45 cm Working Length | Continuous Hydrophilic-Coated Dilator Array | Retrograde Endoscopic Access Corridor

Expiration Date:2026-12-28 - 2028-07-10 

The Cook Medical G46168 (FUS-120045) is a professional-grade, sterile, single-use endourological device engineered to establish a continuous, highly stable, and protective working channel during diagnostic and therapeutic retrograde ureteroscopy procedures. Part of the widely utilized Flexor® Access Sheath Product Portfolio, this system features a 12 French interior diameter (with a low-profile 14 French outer diameter) coupled with an extended 45 cm working length, optimizing it for navigating adult anatomy up to the renal pelvis while maintaining a significantly smaller anatomical footprint than larger 14 French profiles. The core sheath is constructed using a specialized monofilament stainless steel wire coil embedded within a flexible polyurethane matrix, providing unmatched kink-resistance, high radial strength, and extreme flexibility under active manipulation. Treated with an advanced hydrophilic AQ® coating that activates upon hydration, the sheath and its corresponding tapered-tip inner dilator minimize sliding friction and shear stress along the ureteral mucosa. This enables smooth, low-pressure advancement, facilitates rapid, repetitive insertions of flexible scopes or stone baskets, and maintains a low-pressure fluid irrigation outflow tract during high-energy laser lithotripsy interventions.
