4A Biliary Stents - Single Pigtail

SKU: 4A-GE-0004

The Single Pigtail Biliary Stent features a coiled distal or proximal end engineered to prevent stent migration while maintaining effective bile evacuation. Designed for anatomical regions where traditional retention flaps may cause tissue irritation or fail to anchor securely, the pigtail curl acts as a natural mechanical barrier within the duodenum or liver parenchyma. This design is particularly suited for managing proximal bile duct strictures, complex pancreatico-biliary drainage, and cases where prolonged stent stability is required.

Key Benefits

  • Anatomical Pigtail Retention: Curled pigtail segment anchors naturally inside the organ cavity to prevent migration.
  • Smooth Endoscopic Removal: Coiled design uncurls under gentle traction, allowing uncomplicated endoscopic retrieval.
  • Atraumatic Internal Drainage: Multiple side drainage eyes along the pigtail curve maximize fluid intake while preventing tissue occlusion.
  • Flexible Polyurethane Body: Conforms smoothly to tortuous biliary anatomy to minimize focal pressure necrosis.
  • Fluoroscopic Guidance: Full radio-opacity allows real-time position verification during placement and follow-up.

4A Biliary Stents - Standard

Standard Biliary Stents are radiopaque polymer drainage tubes engineered to restore and maintain bile flow in patients with biliary tract obstructions. Used during Endoscopic Retrograde Cholangiopancreatography (ERCP), these stents palliate malignant biliary strictures, relieve benign strictures, and manage post-operative bile leaks. Constructed from flexible medical-grade polyethylene or polyurethane, they feature retention flaps and side drainage holes to ensure stable position retention and uninterrupted biliary clearance.
