Advanced Nitinol-Based Stent Manufacturing Technology
Stents are medical devices used to expand and maintain narrowed or obstructed lumens within the human body.
They require a precise balance of flexibility, radial compression strength, and long-term durability.
Zegatec manufactures nitinol wire-based stents using a semi-automated braiding process, enabling precise structural control and high radial force while maintaining excellent flexibility.
In addition, proprietary thin silicone coating technology and nitriding heat treatment of nitinol wires are applied to improve durability, fatigue resistance, and biocompatibility, ensuring reliable long-term performance inside the body.
