Vascular Stent Delivery Systems
Stent delivery catheters require precise pushability and trackability. The PTFE liner reduces the friction between the stent and the catheter wall, enabling controlled, accurate stent deployment.
Neural Implants and Neurosurgical Devices
In neurosurgery, PTFE Etched Tubes are used in deep brain stimulation (DBS) leads, ventricular shunts, and other neural implants.
Diagnostic and Interventional Endoscopy
PTFE-lined working channels in endoscopes and bronchoscopes benefit from the material's chemical resistance, especially when exposed to enzymatic cleaning agents and disinfectants.
Drug-Coated Balloon (DCB) Catheters
In drug-eluting balloon systems, the PTFE liner ensures smooth balloon folding and unfolding during inflation while remaining chemically inert to the drug coating, preserving drug efficacy during delivery.
