Ureteral access sheath UAS series

renalhydrophilic

Product Description
The Disposable Ureteral Access Sheath is used to facilitate repeated access to the upper urinary tract during endoscopic procedures. It helps maintain a stable working channel, reduces intrarenal pressure, and protects the ureter from repeated instrument exchanges—enhancing procedural efficiency and patient safety.

Product Advantages

• Hydrophilic coating: minimizes insertion friction and protects the ureter during repeated instrument exchanges.
• Stainless steel reinforcement: provides flexibility while resisting kinking and external compression.
• Smooth sheath-dilator transition: enhances insertion efficiency and improves access success rate.
• Integrated spring coil: strengthens pushability and improves handling during navigation.
