Catheter Liners

The first layer or component placed over the mandrel during catheter construction is the liner. The liner will become the inner wall, or lumen, of the completed catheter. Generally, the most desired features of a catheter liner are thin walls and low coefficient of friction (high lubricity). Thin walls maximize intraluminal space while keeping the overall device profile to a minimum. High lubricity reduces friction against devices and tools which pass through the catheter.

Polyimide / PI Glide™ Tubing And Coated Wire

Polyimide (PI) tubing can be produced in extremely small wall thicknesses while still retaining its strength and pushability, enabling it to reach the smallest vasculatures. If increased lubricity is needed, PI Glide™ combines PI and PTFE for a lower coefficient of friction on the inside diameter. The mechanical properties of the liner can be modified by layering PI and PI Glide™ together.
