PI braided tubing is medical catheter tubing made by reinforcing polyimide (PI) tube with a metal braid. PI keeps its strength, heat resistance and thermal stability even at very small sizes, and the braid adds pressure resistance and pushability. Together they raise torque control, flexibility, strength and push performance in one composite tube.
Suited to vascular, structural heart, electrophysiology and urology work. It is used in intravascular ultrasound catheters, endoscopic catheters, vascular stent delivery systems and stone-retrieval basket sheaths.
No. It can be built as PI + wire + PI without PTFE. Add a PTFE inner layer when a low-friction bore is needed.
Yes. Specify the flat wire (e.g. 0.001″×0.003″) and PPI (e.g. 45) and we review at ±0.02 mm wall tolerance. Partial braiding (e.g. 300 mm of 1,800 mm) is also possible.
Yes. TDS · MSDS come with every specification reply. ISO 10993 biocompatibility data varies by grade and lot, so we confirm it with the factory (Linstant) and reply.
Standard sizes start with small sample lots. MOQ and lead time depend on dimensions, material and secondary processing — send OD · ID · wall · tolerance · length · quantity and we reply within one business day.
Inner diameter, wall thickness, length and operating environment — those four settle the item. We reply with TDS, MSDS and MOQ.
