How Can PTFE Catheter Liners helps in Construction of Various Catheter types ?

Before discussing this further, let us first understand what a PTFE Catheter Liner is- in brief.

 

PTFE Catheter Liner- An Introduction

During catheter manufacturing, the liner is the first layer or component to be placed over the mandrel. The completed catheter's lining will serve as its interior wall or lumen. A catheter is used to reduce the friction on the inner walls of a catheter. 

 

Applications of PTFE catheter Liner:

Guide catheters: Allow for the controlled flow of materials inside the catheter walls.

Steered Catheters: Shift the entire length of the tube to modify the direction or form.

Deflectable Catheters: In this situation, you can only change the direction of the flow by moving the tip of the catheter.

 

Why is PTFE used to line catheters?


 

PTFE is Polytetrafluoroethylene and is quite popular in the medical industry due to its use as a Catheter Liner. Its unique properties such as being chemically inert, having the highest friction-resistance, having an extreme working thermal range of -270 ̊C to 260 ̊C, excellent dielectric insulator, and being biocompatible, makes it an ideal choice for developing PTFE Catheter Liners. 

Furthermore, it cannot be melt-processed in this form, but professionals have created a shape that you can call FEP (Fluorinated ethylene propylene) or FEP, identical to PTFE wholly. It is still perfect for creating items that need great clarity, chemical resistance, and relatively low stiffness because it has a low heat shrink temperature and is UV resistant.

To further facilitate the smooth passage of things through multi-lumen tubing, we can add liners to the individual lumen. DTC has created a wide variety of PTFE Catheter Liners using the latest technology which is in wide use by the leading medical equipment manufacturing businesses globally. 

 

Characteristics of a PTFE Catheter Liner:

Typically, thin walls and a low coefficient of friction are the characteristics of a catheter liner that are most desirable. To maximize intraluminal space while minimizing the overall device profile is possible with thin walls. High lubricity lessens resistance to equipment and devices that pass through the catheter. Successful catheter design still depends heavily on liner selection. 

 

Lubricity

Due to its high lubricity, professionals give top priority to using PTFE for designing Catheters and Liners. The fact that PTFE has the lowest coefficient of friction of any polymer is particularly advantageous when taking the catheter's interior diameter (ID) into account. Since intraluminal devices (such as stents, balloons, etc.) pass through the catheter's working channel with less force due to high lubricity, the success rate of the procedure rises.

 

 

 

Thin walls:

Another significant benefit of PTFE for catheter design is its ability to process into tubes with incredibly thin walls and precise tolerances. This is in addition to its low coefficient of friction. The working channel of the catheter can increase while maintaining a minimal overall device profile thanks to a catheter liner with incredibly thin walls. Thin walls and other characteristics of the catheter liner contribute to the catheter's strength and flexibility. However, the catheter liner's actual production process also has a significant impact on how well it performs, beyond just its physical dimensions.

Catheters use PTFE to lessen friction, and FEP heat-shrink tubing offers flexibility, clarity, and lubricity. In every instance, these materials increase patient comfort and healthcare effectiveness. Our professionals at DTC are working diligently to improve the structural designs and working span of invasive products. Nevertheless, medical device producers must match the application's needs to the size and mechanical performance characteristics of the available liner options for every catheter project.

 

Guide Catheters- an application of PTFE Catheter Liners:

A Guide Catheter enables the convenient placement of lasers, stents, and balloons for angioplasty procedures. For successful interventional cardiology, an ideal guide catheter is crucial. PTFE serves the purpose of a baseliner while manufacturing Guiding Catheters. It provides an exceedingly smooth surface. 

A guide catheter is preferred over a simple catheter in critical cases due to the characteristics mentioned above-

  • Stiffer shaft 
  • Ultra-thin walls 
  • Larger internal lumen diameter
  • More angulated tip
  • Reinforced construction

All the above features make it an ideal choice for complex anatomy operations that requires critical handling.

 

Benefits of a Guide Catheter:

  • Excellent shape retention capacity giving maximum reliability for long-term operation
  • Frictionless internal movements in the vessel
  • Soft automated tip to reduce the damage to the tissues and vessels
  • Variable flexibility
  • Highly stable
  • Support for device & wire transport
  • Compatible with the lumen and other devices

 

We are known for designing anatomy-based guide catheters and other products.
