Resonetics’ nitinol tubes play a key role in a wide range of interventional devices such as stents, heart valves, and catheter delivery systems.

With over 30 years of experience, we melt raw nitinol, create bars, and use precision die drawing to create 3 different grades of tubing (Standard, Precision, and Premium) in a range of sizes and finishes, all in-house. From micro-scale hypotubes to large premium tubes, every tube meets the tight tolerances required. We have the right nitinol tube for your application, no matter the complexity. Read more about our tube grades below and find the right one for your project.

Precision

We specialize in precision nitinol tubing solutions with laser-cut and shape set capabilities tailored for stent applications, offering two diameter groups. The first includes outer diameters ranging from 0.065" to 0.197" (1.65–5 mm) with tight tolerances of ±0.0005" (12.7 µm), ensuring superior accuracy. The other is designed for diameters exceeding 0.198" (>5 mm) with tolerances of ±0.0008"–0.001" (20.3–25.4 µm). Both groups deliver over 90% precision, meeting the highest standards for application-specific requirements in medical device manufacturing.

Applications:

Temporary and permanent implantables without high mechanical stress
Products that depend on consistent material performance, but do not have extremely high fatigue requirements, and can tolerate slightly lower concentricity
Delivery Aides
Endografts
Stents
Filters
Blood Clot Filters
Orthopedic Implants
Peripheral Vascular Applications
