▶ Multi-layer tubing is widely used in medical applications that require unique performance characteristics of catheter designs, particularly tri-layer designs. Tri-layer tubing can be designed with specific materials on the inner diameter to improve ID frictional properties, making it more lubricious. For example, a coextruded tube can provide a lubricious inner lining for a guide wire to smoothly travel through during a percutaneous transluminal coronary angioplasty (PTCA), neurology, oncology, and interventional radiology.

▶ Coextruded medical tubing is indicated for various medical applications, including IV therapy, cardiac catheterization, respiratory therapy, dialysis, and endoscopy. Coextruded tubing is used when multiple functions need to be performed through a single device or when specific properties such as flexibility, clarity, and strength are required.
