Nitinol Tube with Platinum Core
Nitinol Tube with Platinum Core: Precision-Engineered Hollow Structures with Enhanced Radiopacity
Nitinol Tube with Platinum Core Description:
A composite structure featuring an outer nitinol tube (diameter 0,5–20 mm, wall thickness 0,05–1 mm) encasing a solid or hollow platinum core (diameter typically 10–50% of the tube’s inner diameter). Crafted via co-extrusion or sleeving, followed by thermal treatment to set nitinol’s transition temperature (30–37°C).
Nitinol Tube with Platinum Core Key Features:
- Superelasticity from nitinol, with up to 10% recoverable strain.
- Exceptional radiopacity from platinum, surpassing stainless steel and CoCr.
- Shape memory activated at body temperature, paired with platinum’s corrosion resistance.
Nitinol Tube with Platinum Core сertification and Standards:
- ASTM F2063: Governs nitinol properties for medical use.
- ASTM F560: Applies to platinum in surgical implants.
- ISO 25539: Específico para dispositivos endovasculares como stents.
- ISO 13485 and ISO 10993: Required for quality management and biocompatibility; FDA and CE approvals mandatory.

Materiales
Nitinol tube with a platinum core combines the shape-memory and superelastic properties of nitinol (NiTi, 50–55% nickel, 45–50% titanium) with the radiopacity and inertness of pure platinum (Pt). This hybrid design offers tensile strength of 1000–1200 MPa from nitinol and a density boost from platinum (~21,45 g/cm³), ideal for advanced medical devices.
Solicitud
- Radiopaque Stents: Tubes (3–10 mm Ø) expand in vessels, with the Pt core ensuring visibility under X-ray or fluoroscopy for precise placement.
- Endovascular Navigation: Used in guide catheters (0,5–2 mm Ø), where the Pt core aids tracking during complex procedures.
- Implantable Sensors: Larger tubes (10–20 mm Ø) with Pt cores serve as markers in long-term implants like pacemakers.
Presupuesto
- Outer Diameter: 0,5–20 mm
- Wall Thickness (Nitinol): 0,05–1 mm
- Platinum Core Diameter: 0,05–5 mm (varies with tube size)
- Composite Density: 8–15 g/cm³ (depends on Pt:NiTi ratio)
- Tensile Strength: 1000–1200 MPa (nitinol-driven)
