Guiding Catheter Types with PTFE Catheter Liner

Guide catheters come in a variety of types, each designed for specific applications. Here are a few common types:

Over the Wire Catheters

These catheters are used in procedures where precise placement is necessary. They are guided into place using a guidewire.

Balloon Guide Catheter

These catheters have a small inflatable balloon at the tip, which can be used to widen narrow or blocked arteries.

Exchange Length Catheters

These are longer catheters used in complex procedures where standard-length catheters may not reach the desired location.

Each type of guide catheter has its own benefits and is chosen depending on the medical procedure’s unique requirements.

The Manufacturing Process of PTFE Lined Catheters

Material Selection

The production process of PTFE extruded guide catheters begins with the selection of high-quality PTFE. This material was chosen for its distinctive features, which include reduced friction, chemical resistance, and temperature resistance.

Extrusion Process

The PTFE is then heated and pressed through a die to form a tube during the extrusion process. This tube creates the catheter’s lining, resulting in PTFE tubing.


After that, the PTFE extruded tubing is put into the catheter body, which is usually constructed of another flexible material. To guarantee that the lining fits exactly within the catheter body, the assembling procedure must be precise.

Quality Control

After the guide catheter is built, it is subjected to stringent quality control examinations. These tests confirm that the catheter complies with all applicable medical requirements and that the PTFE lining is properly installed and free of flaws.

The Multifaceted Impact of Guide Catheters with PTFE Extrusion on Patient Care
