Medical Custom PTFE Multi-Lumens Tube
Medical Custom PTFE Multi-Lumen Tube is a precision tubing solution developed for minimally invasive medical devices, including endoscopic instruments, laparoscopic devices, and customized catheter systems.
Made from high-purity PTFE material, the tube integrates multiple independent channels into one compact structure. Each lumen can be customized for different functions, such as guidewire passage, fluid delivery, gas transmission, or instrument control.
Zetai provides customized PTFE multi-lumen tubes based on customer drawings, including lumen quantity, inner diameter, outer diameter, wall thickness, length, and cross-sectional design.

Product Features
Custom Multi-Lumen Design
The lumen structure can be customized according to different medical device requirements.
Available options:
• 2 lumen
• 3 lumen
• Multiple lumen configurations
Each channel can be designed for different functions, including:
• Guidewire movement
• Irrigation
• Suction
• Gas transmission
• Instrument operation
Smooth PTFE inner surface and non-stick properties
PTFE naturally provides a low-friction surface, which helps:
• Reduce resistance during guidewire movement
• Improve fluid flow performance
• Support smooth device operation
This makes PTFE suitable for minimally invasive instruments requiring reliable internal channels.
Stable Dimensional Control
Medical devices require consistent tubing dimensions.
Our manufacturing process focuses on controlling:
• Outer diameter
• Inner lumen size
• Wall thickness
• Concentricity
• Surface quality
Stable dimensions help improve assembly consistency during medical device production.
Advantages
One Tube, Multiple Functions: Multiple channels can be integrated into one tubing structure, saving internal space in compact medical devices.
Suitable for Complex Minimally Invasive Devices: Designed for applications where multiple functions need to be performed through a small diameter component.
Low Friction Performance: The smooth PTFE surface helps reduce friction between the tube wall and internal components.
Non-stick properties: Reduce the adhesion of blood, tissue fluids, and drug residues.
Quality Control Process

Dimensional Inspection
Focuses on measuring the catheter outer diameter, tapered section dimensions, and critical lengths.

Visual & Surface Inspection
Focuses on checking for impurities, foreign objects, scratches, damage, or surface defects.

Lumen Dimension Measurement
Uses optical projection or microscopic measurement equipment to verify that the inner diameter, wall thickness, and concentricity of each lumen are within tolerance limits.

Order Quantity Verification
Checks that product quantities, batch labels, and packing lists align with order specifications.
