Marqueurs platine-iridium (marqueurs PtIr)

Platinum-Iridium Markers: High-Contrast Tags for Imaging and Tracking in Medicine

Platinum-Iridium Markers Description:

Minuscules marqueurs en platine-iridium, généralement des sphères, des disques ou de courts cylindres (0,1 à 3 mm de diamètre), fabriqués par micro-usinage ou par découpe au fil. Ces marqueurs exploitent la densité et la radio-opacité de l'alliage pour l'imagerie médicale.

Platinum-Iridium Markers Key Features:

Unmatched radiopacity, making them visible under X-ray, CT, and fluoroscopy.
Extreme chemical inertness, resisting degradation in the body.
Precision sizing for compatibility with minimally invasive delivery systems.

Platinum-Iridium Markers Certification and Standards:

ASTM F560: Applies to Pt-Ir alloys in medical devices.
ISO 10993: Ensures biocompatibility for implanted markers.
ISO 25539: Relevant for endovascular devices using markers.
FDA (e.g., 510(k) clearance) and CE marking; specific radiopacity specs per manufacturer.

Why Platinum-Iridium?

Platinum-iridium’s blend of durability, radiopacity, and biocompatibility—fortified by alloys like 90/10 Pt-Ir and upheld by strict standards—makes it indispensable for cutting-edge medical solutions. Need more details on applications or custom designs? Contact us today!

Matériels

Platinum-iridium (Pt-Ir), an alloy typically composed of 90% platinum and 10% iridium (though ratios may vary), combines platinum’s ductility and biocompatibility with iridium’s extreme hardness and corrosion resistance. With tensile strength ranging from 900–1200 MPa and a melting point around 1800°C, Pt-Ir is a premium choice for medical devices.

Application

Tumor Marking: Markers (0,5–2 mm Ø) implanted to guide radiotherapy or track tumor movement.
Vascular Tracking: Small tags (0,1–1 mm Ø) on stents or catheters enhance procedural accuracy.
Orthopedic Alignment: Discs (1–3 mm Ø) embedded in implants for post-surgical monitoring.
