As the demand for minimally invasive treatment of biliary diseases continues to grow, EVT Medical has become the first Chinese manufacturer to introduce a domestically developed PTBD (Percutaneous Transhepatic Biliary Drainage) Catheter Set, providing a safer and more efficient solution for the treatment of biliary obstruction.

The PTBD catheter set is designed to establish percutaneous transhepatic access for endoscopic entry into dilated bile ducts, making it suitable for biliary drainage, biliary obstruction management, and a wide range of diagnostic and interventional procedures.

A Comprehensive PTBD Solution for Clinical Practice

The EVT Medical PTBD catheter set includes:

• Drainage Catheter
• Dilator
• Peel-away Sheath
• Puncture Needle
• Guidewire

The integrated system is designed to simplify the PTBD procedure while improving procedural efficiency and clinical performance.

Optimized Design for Enhanced Clinical Performance

Radiopaque Puncture Needle

The puncture needle features a sandblasted tip with an internal air channel, providing enhanced dual-contrast visualization to improve puncture accuracy during intervention.

High-Support Nitinol Guidewire

The guidewire is constructed with a nitinol core for excellent support and flexibility. Its hydrophilic-coated tip minimizes insertion resistance, enabling smoother device advancement.

Medical-Grade Dilator

Manufactured from medical-grade polyethylene, the dilator offers an optimal balance of stiffness and flexibility for efficient tract dilation.

Peel-away Sheath

The peel-away sheath is available in both negative-pressure and standard configurations. Its tapered tip design ensures a smooth transition and facilitates easy insertion.

Large-Lumen Silicone Drainage Catheter

The straight single-lumen silicone drainage catheter features a large internal diameter, helping maintain efficient and unobstructed biliary drainage.
