Product Description

Product Description

Core Features

1. Adjustable Pressure Relief Valve

Maintains low intrarenal pressure while ensuring procedural efficiency, reducing the risk of potential complications.

2. Hydrophilic Ultra-Smooth Coating

Provides an ultra-low friction outer surface, improving procedural efficiency and minimizing tissue trauma.

3. Superior Deflection Performance

Enables direct access to lesions in complex anatomical environments.

4. Reinforced Coil Construction

Provides mechanical support, ensuring lumen patency and operational stability under demanding conditions.

5. PTFE Inner Liner

Ensures a smooth inner lumen with reduced friction, facilitating easy instrument insertion and removal.

Intended Use

Flexible ureteral access sheaths are intended to establish a working channel through the ureter during ureterorenoscopy (fURS/RIRS). They allow repeated passage of flexible ureteroscopes and ancillary instruments (laser fibers, graspers, baskets) while protecting the ureteral wall, maintaining irrigation flow, and reducing intrarenal pressure. The deflectable tip improves access to the lower pole and other hard-to-reach calyces.
