Tubes en Nitinol (tube NiTi)
Nitinol Tubes: Precision-Engineered Hollow Structures for Advanced Medical Devices
Nitinol Tubes Description:
Structures cylindriques creuses en nitinol, fabriquées par extrusion ou étirage. Ces tubes présentent des diamètres allant de 0,5 mm à 20 mm, avec des épaisseurs de paroi de 0,05 à 1 mm.
Nitinol 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.
Nitinol Tubes 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.

Matériels
Nitinol (NiTi), a nickel-titanium alloy, is renowned for its superelasticity and shape memory, making it a game-changer in medical applications. With a tensile strength of up to 1200 MPa and elastic modulus of 40–75 GPa, nitinol excels in demanding environments.
Application
- Stents: Coronary stents (expanding from 3–8 mm to 10–30 mm) support blood vessels.
- Endovascular Devices: Larger tubes (5–10 mm) reinforce aortic walls against aneurysms.
- Endoscopy: Thin tubes (0,5–1 mm) serve as flexible conduits for tools.
