Coil Reinforced Tubing
Kink resistance, pressure holding, burst strength, and other properties of medical device tubing can be improved with coil reinforcement. DUKE Extrusion offers coil reinforced tube for catheter manufacturer applications and other medical uses. We can help you develop the ideal coil reinforced tube for your needs through material recommendations and design assistance.
We utilize state-of-the-art custom equipment to produce coil reinforced composite tube. Pic-per-inch (PPI) can be varied along the length of the tube to provide access points for ports or the introduction of other devices through the wall of the tubing, as is common with irrigation cannulas and catheters.
Coil filaments can be composed of materials including stainless steel, nitinol, Kevlar, PEEK, fiberglass, carbon fiber, PET, platinum, iridium, tungsten, ultra-high weight molecular polyethylene (UHWMPE), and others.
Coil filament geometries can include ribbon, round, or flat. Single or multi-filament coils can be used. DUKE Extrusion will help you determine the best material, the best geometry, and the best coil layout for your medical device tubing application. See our Coiling page for more information.
Coil reinforced composite tube offers performance similar to braid reinforced tubing and laser cut hypotube. Each method offers its own advantages that may make it more suitable to your application. DUKE can recommend the best reinforcement method for your needs, with consideration to performance, cost, and other factors.
