4A Biliary Stents - Standard

SKU: 4A-GE-0002

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.

Key Benefits

  • Effective Biliary Drainage: Multi-hole drainage design maintains consistent bile flow through malignant and benign strictures.
  • Anti-Migration Flaps: Integrated retention flaps minimize unwanted distal or proximal stent displacement within the bile duct.
  • High Radio-Opacity: Fully radiopaque polymer allows accurate placement and monitoring under real-time fluoroscopy.
  • Biocompatible Material: Smooth, flexible construction resists encrustation and conforms to natural duct curvature.
  • Universal Endoscopic Delivery: Compatible with standard 0.035" guide wires and standard ERCP pushing catheters.

4A Biliary Stents - Single Pigtail

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.

4A Biliary Stents - Double Pigtail

The Double Pigtail Biliary Stent is engineered with coiled curl loops at both its proximal and distal ends to provide maximum anchor stability within the biliary tree and duodenum. By securing one pigtail in the bile duct and the other within the duodenal lumen, this stent virtually eliminates both upward (proximal) and downward (distal) migration risks. It is widely utilized for benign strictures, pancreatic pseudocyst drainage, and long-term palliation where stent displacement poses a high clinical risk.

4A Biliary Stents - Straight

The Straight Biliary Stent is a streamlined endourological drainage device designed for simple, direct insertion through straightforward extrahepatic bile duct strictures. Featuring a linear shaft with tapered ends and peripheral side holes, it provides an unobstructed pathway for bile flow from the hepatic ducts to the duodenum. Its minimalistic profile makes it an excellent choice for rapid deployment during diagnostic or therapeutic ERCP procedures where complex anatomical curvature is absent.
