4A Biliary Stents - Amsterdam

SKU: 4A-GE-0003

The Amsterdam Biliary Stent is a classic endourological polymer stent designed for high-efficiency biliary decompression during ERCP procedures. Characterized by its specialized side holes and double flap mechanism at both ends, the Amsterdam design offers exceptional resistance to migration while optimizing bile throughput. Its rigid yet flexible polyethylene construction provides excellent column strength, making it ideal for traversing tight, calcified, or malignant common bile duct strictures.

Key Benefits

  • Dual Anti-Migration Mechanism: Opposing distal and proximal retention flaps securely anchor the stent across the stricture.
  • High Flow Efficiency: Optimized lumen-to-wall ratio ensures rapid bile drainage and reduces sludge buildup.
  • Superior Column Strength: Pushing-resistant shaft allows smooth advancement through hard or tight biliary strictures.
  • Radiopaque Tracking: Infused with barium sulfate to ensure clear fluoroscopic visibility during deployment.
  • Trauma-Free Profile: Tapered leading edges ease insertion past the Papilla of Vater without tissue tearing.
