GlideAccess is a versatile, hydrophilic-coated ureteral access sheath engineered for atraumatic entry into the upper urinary tract—simplifying endoscopic procedures such as ureteroscopy and stone management. Featuring a unique tip-expanding system, the sheath transitions gently from its dilator to the external surface, minimizing patient discomfort and reducing mucosal trauma. With stainless-steel coil reinforcement, radiopaque markers, and a dilator lock mechanism, GlideAccess offers secure, anti-kink performance across a variety of lengths and diameters.

Atraumatic Tip Transition
  • Unique Tip-Expanding System: Ensures a smooth, gradual opening that decreases friction at the ureteral orifice, reducing tissue irritation or injury.
  • Protective Design: Minimizes patient discomfort during insertion or repositioning.
  • Secure Sheath-Dilator Connection: Prevents accidental separation, facilitating consistent advancement and controlled placement.
  • Visual Control of Fixation: Confirms at-a-glance that the dilator is correctly engaged with the sheath.
  • PTFE Inner Layer: Ensures a low-friction lumen for smooth device passage (e.g., scopes, retrieval baskets), avoiding potential hang-ups or drag.
  • Stainless-Steel Coil Reinforcement: Maintains sheath patency under bending forces, imparting robust anti-kink characteristics—critical in tortuous ureteral anatomy.
  • Sheath & Dilator Tip Visibility: Allows precise fluoroscopic or endoscopic confirmation of device position, key in complex anatomy.
  • Efficient Localization: Helps operators define the exact transition point of the tip for atraumatic positioning.
  • Enhanced Navigability: Reduces friction along ureteral walls, simplifying sheath advancement and retrieval.
  • Lower Tissue Trauma: Minimizes ureteral irritation, diminishing bleeding or edema risks.
  • Multiple Lengths: 35 or 45 cm suits various patient anatomies or scope placements.
  • Inner & Outer Diameters (CH/FR): Wide range—10/12, 12/14, 14/16—covering typical ureteral requirements for stone extraction or endoscopic interventions.

临床优势与应用

Facilitating Ureteroscopy
  • Repetitive Instrument Exchange: Ensures comfortable and efficient scope passes, limiting repeated trauma to the ureteral orifice and walls.
  • Stone Retrieval & Laser Lithotripsy: Streamlines manipulations of baskets, laser fibers, or retrieval devices, enhancing operative speed.
  • Reliable Anti-Kink Design: Maintains consistent patency for irrigation outflow and instrument movement, potentially lowering overall operative durations.
  • Atraumatic Transition: Minimizes scope deflections or repeated sheath reintroductions, boosting procedural efficiency.
  • Lower Mucosal Injury: The gentle tip transition mitigates excessive stress or friction within the ureter.
  • Secure Placement: Locking mechanism keeps the dilator-sheath assembly stable, alleviating sudden disconnections or misplacement.
  • Hydrophilic Coating: Beneficial in managing acute angles, strictures, or narrower ureteral segments.
  • Stainless-Steel Coil: Reinforces radial strength and consistent luminal diameter for large or rigid endourological instruments.
