Coiled Tubing for Catheters & Other Medical Devices

Thin wall catheter tubing can be reinforced with metal or polymer coil to provide kink resistance and crush resistant benefits. Coil reinforced tubing uses an internal helical coil spring and includes an elongated tubular outer wall. It is engineered to eliminate kinking or collapsing, while still maintaining flexibility. Duke Extrusion’s coiled tubing is ideal for catheters and other medical devices where tubing performance is critical. Coil reinforced tubing materials and coil design can be optimized for certain applications, depending on product requirement specifications. The numerous options that can be specified include:

Flat ribbon or round Variable pitch Wire temper Multifilar coils

Gap distance Direction of winding Multiple layers of coils Coil on taper

Coiled Tubing & Extrusions 

At Duke Extrusions we can add coil reinforced catheter tubing to extrusions in diameters from 0.010"-up to 1". Coiled plastic tubing can be added to multi-lumen extrusions in numerous configurations, with one or more lumens above or below the coil filament as needed. Each individual lumen can also be reinforced with coils with or without a PTFE or polyimide liner for added lubricity and strength.
