Multi-Durometer Braid Reinforced PTFE Lined Tubing
Braid reinforced multi-durometer PTFE lined tubing provides several advantages over non-reinforced varieties. Improved torque response, improved kink resistance, and better pushability are features of braid reinforced tubing that allow for steering by rotation of fixed shape tips at the distal end, and for controlling device deployment systems remotely where precision and performance are to be optimized.
Duke Extrusion offers a range of multi-durometer PTFE lined braided tubing, with a variety of braid reinforcement materials, including flat and round stainless steel wire braiding, polymeric filament braiding, carbon and glass fiber braiding, and specialty metal braiding such as nitinol and platinum alloys.
Sizes from 2 to 24 French are available, with high angle pics per inch (PPI) and low angle PPI options. This specialty medical tubing extrusion is available with marker bands at the tip for visualization under fluoroscopy. Hydrophilic outer surface coatings are also available.
We offer quick turn development of prototypes and custom varieties, manufactured to your specifications. Our custom multi-durometer PTFE lined braided tubing can include as many as 7 different durometer segments, though most applications require only 3-5 segments. PPI, liner wall thickness, and other factors can be modified as required.
Laser cut hypotube with PTFE liner and multi-durometer thermoplastic outer surface is also available as a design option. Our customized configurations offer similar performance benefits, and may be better suited to applications where wall thickness and hoop strength are to be optimized, particularly for products with larger diameters (10-24Fr). Please visit our laser cut hypotube page for more information, or contact us for help in choosing the best medical tubing extrusion for your application.
Our multi-durometer braid reinforced PTFE tubing is provided with braid terminations co-linear to the end of the PTFE liner. Non-reinforced material continues to run past the end of the braid, resulting in a slightly smaller O.D.
