4A PTBD Catheter (Percutaneous Transhepatic Biliary Drainage Catheter)

SKU: 4A-GE-0011

The Percutaneous Transhepatic Biliary Drainage (PTBD) Catheter is a specialized interventional radiology device used to decompress obstructed biliary systems via a percutaneous transhepatic approach. Designed for external biliary fluid evacuation, this catheter provides a vital solution when endoscopic drainage (ERCP) is technically unfeasible or anatomically contraindicated.

Key Benefits

  • Secure Pigtail Retention Mechanism: Mac-Loc or thread-locking mechanism secures the distal pigtail loop inside the bile duct, preventing accidental dislodgement.
  • Kink-Resistant Polyurethane Body: High structural integrity maintains internal cross-sectional diameter even across tight intercostal pathways.
  • Large Drainage Perforations: Strategically positioned side holes maximize biliary evacuation rates and resist occlusion from biliary sludge.
  • Hydrophilic Tip Coating: Reduces insertion friction over guidewires, allowing smooth progression through fibrotic hepatic parenchyma.
  • Clear Depth Marking: High-contrast centimeter depth indicators provide visual alignment during fluoroscopic positioning.

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.
