PTFE Lining

PTFE liners are used to lower the friction on the internal diameter of catheter tubing.  PTFE liners are generally a thin layer of PTFE with an etched outer surface that is bonded to other polymers through a thermal lamination.  Common applications include guiding catheters, deflectable catheters, introducer sheaths, and device delivery systems. 

PTFE liners can be added to individual lumens in multi-lumen tubing.   The combination of using a PTFE liner with braid or coil reinforcement in a composite tubing is used to produce tubing with low friction for passage of other devices through the lumen, with kink resistance, torque, and variable stiffness if more than one outer jacket material is used.  When used as a liner for deflection wires or cables within the wall of a catheter tubing, the PTFE liner reduces the force to deflect the tip of a catheter. 

PTFE liners range in wall thickness from 0.0005” – 0.005” depending on the diameter of the tubing and the specific application.  The ID of PTFE liners can range from 0.005” – 0.5”.
