4A Ureteral Access Sheath

SKU: 4A-UR-0002

The 4A Ureteral Access Sheath is a single-use endourological device designed to establish a continuous working channel during retrograde intrarenal surgery (RIRS) and flexible ureteroscopy. Featuring a wire-reinforced shaft and hydrophilic coating, it facilitates repeated scope passages, optimizes intrarenal pressure control, and protects ureteral mucosa during stone management. Its atraumatic tapered dilator tip ensures smooth, low-friction insertion across the ureterovesical junction.

Key Benefits

  • Atraumatic Tapered Dilator: Seamless dilator-to-sheath transition minimizes mucosal trauma and shear force during placement.
  • Kink-Resistant Coil Reinforcement: Stainless steel coil integration maintains 1:1 lumen integrity through tortuous anatomy.
  • Hydrophilic Exterior Coating: Friction-reducing coating enables effortless sheath advancement and easy scope navigation.
  • Intrarenal Pressure Regulation: Sustained fluid outflow around flexible scopes lowers renal pelvic pressure to improve visibility.
  • Ergonomic Snap-Lock Hub: Secure dual-locking mechanism prevents accidental dilator displacement during advancement.
