PTFE Liner
PTFE (polytetrafluoroethylene) is a synthetic fluoropolymer that is used as a liner in catheters due to its unique properties. PTFE has a very low coefficient of friction and is a highly durable material with excellent tensile strength. Catheter liners made of PTFE can withstand the stresses of use in medical devices and resist breaking or tearing.
PTFE is used as a liner in catheters because it provides a smooth, low-friction surface that helps reduce the risk of infection and tissue damage. They are also biocompatible so that most people won’t experience an allergic reaction or any negative response.

Guiding Catheter
Guiding catheters are typically composed of biocompatible materials such as polyurethane or nylon, chosen for their flexibility, durability, and compatibility with bodily tissues. The catheter shaft is reinforced with braided or coiled wires to provide structural support and torqueability while maintaining flexibility for navigation through tortuous vascular anatomy. Soft, atraumatic tips minimize trauma to blood vessels during insertion and positioning. Radiopaque markers or bands incorporated into the catheter shaft enhance visibility under fluoroscopy or other imaging modalities, allowing for precise navigation and positioning during procedures. Demax’s guiding catheters are engineered with advanced materials and design features to optimize performance and safety, ensuring successful outcomes in a wide range of interventional procedures.
