Medical Etched PTFE Multi-Lumen Tubing
Medical Etched PTFE Multi-Lumen Tubing is a customized PTFE tubing solution designed for medical catheter and minimally invasive device applications.
Manufactured from medical-grade PTFE resin, the tubing is produced through precision extrusion and controlled etching processes.
The multi-lumen structure allows different channels to work independently, while the etched surface improves bonding performance with outer layers or other medical materials.
With excellent chemical resistance, low friction and stable dimensional control, our PTFE multi-lumen tubes are suitable for applications such as microcatheters, delivery systems, and other customized medical devices.
We provide customized solutions based on customer drawings, including lumen number, dimensions, wall thickness and tubing length.

Advantages
Independent Multi-Channel Transmission: Multiple lumens allow different media, guidewires or signals to pass through separate channels.
Compact Device Design: Combining multiple channels into one tube helps reduce catheter size and simplify device structure.
Smooth Inner Surface: The low friction property of PTFE helps provide smooth movement of fluids and medical components.
Custom Design Capability: We support customized lumen structures, dimensions, tolerances and surface treatments according to customer requirements.
Why Choose Etched PTFE Multi-Lumen Tubing?
Multiple Channels in One Tube
Multi-lumen design allows different fluids, wires or signals to pass through separate channels within one tube structure.
Benefits:Reduce device size/Simplify catheter design/Support multiple functions
Improved Bonding Performance
PTFE naturally has excellent chemical resistance but is difficult to bond.
Surface etching modifies the PTFE surface and improves adhesion with outer catheter materials.
Excellent PTFE Properties
PTFE provides:Low friction/Chemical resistance/Temperature stability/Good dimensional stability
Applications
Microcatheter Systems
Used as an inner tubing component for neurovascular and cardiovascular catheter systems requiring multiple channels and smooth transmission.
Drug Delivery Catheters
Multi-lumen structure allows separate channels for drug delivery, guidewire movement or other functions.
Endoscopic & Minimally Invasive Devices
Suitable for customized endoscopic instruments requiring compact tubing structures.
