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 Reinforced Tubing

Polyimide (PI) tubing can be produced in a range of ID sizes with thin walls and extremely tight tolerances while still retaining its strength and pushability, enabling it to reach the smallest vasculatures. Zeus PI tubing products help you adhere to REACH and EU MDR guidelines regarding SVHC/CMR restricted substances.* When enhanced lubricity is needed, PI Glide™, a PI/PTFE composite, provides up to 25% lower coefficient of friction.

Braid and coil reinforced polyimide tubing are available for challenging applications that require enhanced torque, flexibility, kink resistance, improved pushability, or increased strength. These features help medical device engineers optimize their medical device designs and fine-tune key performance characteristics, paving the way for improved procedural outcomes and increased patient safety. Reinforced PI tubing can be produced in full-load and half-load braid patterns, as well as clockwise and counter-clockwise coiling, with various PPI (picks per inch) and WPI (wraps per inch) to meet your design requirements.

Key Benefits and Capabilities:

• Maintains Properties with Thin Walls and Tight Tolerances
• Customizable Lubricity
• Customizable Mechanical Properties

*Our thorough analytical test results indicate that no SVHC/CMR restricted substances are intentionally included in Zeus-supplied polyimide products at levels above the 0.1% threshold outlined by REACH and EU MDR.
