4A PTBD Catheter (Percutaneous Transhepatic Biliary Drainage Catheter)
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.
