Nitinol Tubes: Precision-Engineered Hollow Structures for Advanced Medical Devices
Nickel Titanium Alloy Tubes Description:
Hollow cylindrical structures made from nitinol, crafted through extrusion or drawing. These tubes range from small (0,5 mm) to larger diameters (20 mm) with wall thicknesses of 0,05 – 1 mm.
NiTi Tubes Key Features:
- Superelasticity with up to 10% recoverable strain.
- Shape memory activated at 30–37°C (body temperature).
- Laser-cuttable for intricate designs like mesh patterns.
Certification and Standards:
- ASTM F2063: Governs chemical composition and properties of medical-grade nitinol.
- ISO 13485: Mandatory quality management certification for manufacturers.
- ISO 25539: Specific to endovascular devices like stents.
- Additional approvals: FDA (U.S.) or CE marking (EU) required for market entry.
