This PTCD biliary pigtail drainage catheter is a fully integrated locking catheter system designed for percutaneous transhepatic cholangial drainage (PTCD). Engineered for both external and internal‑external drainage modes, it provides clinicians with a versatile solution for biliary decompression in obstructive and post‑procedural settings. The system is optimized for stability under imaging guidance and patient comfort during short‑ to long‑term drainage.

• Catheter Size Range: 7F, 8.5F, 10F, 12F, 14F
• Working Length: 25 cm, 30 cm, 35 cm, 40 cm
• Fixation: Integrated locking hub with suture wings
• Tip Design: Multi‑loop pigtail with radiopaque marker
• Trocar Compatibility: Diamond‑tip or conventional needle access

• External Mode: Tip placed above obstruction for direct external drainage
• Internal‑External Mode: Tip advanced past obstruction, allowing bile to flow internally to duodenum; external port can be closed for internal‑only drainage

• Secure Locking Hub – Reduces catheter migration and dislodgement
• Enhanced Radiopacity – Full‑length marker stripe and tip marker for clear fluoroscopic visualization
• Soft, Kink‑Resistant Material – Medical‑grade polyurethane maintains patency during flexion
• Multi‑Loop Retention – Helical pigtail design enhances position stability in the biliary tree
• Ultrasound & Fluoroscopy Compatible – Suitable for all common image‑guidance approaches

• Malignant biliary obstruction (palliative drainage)
• Benign stricture management
• Pre‑operative biliary decompression
• Post‑surgical or traumatic bile leak control
• Diagnostic cholangiography and bile sampling

Manufactured in an ISO 13485‑certified facility. Single‑use, sterile, EO packaged. Suitable for interventional radiology, gastroenterology, and hepatobiliary surgical applications.
