Overview of Platinum Iridium Wire Pt90/Ir10
Platinum Iridium Wire Pt90/Ir10 (90% platinum, 10% iridium) is a high-performance medical-grade alloy engineered for demanding applications in interventional and minimally invasive instruments. Its exceptional radiopacity, combined with outstanding biocompatibility and mechanical stability, makes it the preferred material for manufacturing radiopaque marker bands on catheters and other visualization components in minimally invasive devices.
This high-density platinum iridium alloy ensures clear fluoroscopic visualization during complex procedures in interventional cardiology, radiology, and neurovascular interventions, helping physicians precisely position catheters, guidewires, and delivery systems in real time.
Features of Pt90/Ir10 Platinum Iridium Alloy Wire
Superior Radiopacity & High Density — Excellent X-ray and fluoroscopic visibility due to high atomic density (21.56 g/cm³), ideal for radiopaque marker bands and catheter components.
Proven Biocompatibility — FDA-recognized material suitable for long-term contact with bodily tissues and fluids.
Outstanding Corrosion Resistance — Resists physiological environments, ensuring durability and safety in interventional instruments.
Excellent Formability & Ductility — Easy to draw into fine wires and form into thin-walled marker bands or complex shapes for minimally invasive devices.
Reliable Mechanical Properties — Tensile strength of 380–620 MPa (depending on temper) provides the right balance of strength and flexibility for medical wire applications.
Consistent High-Purity Alloy — Precise Pt90/Ir10 composition delivers repeatable performance in precision medical manufacturing.
Implantable Medical Applications of Platinum Iridium Wire
Platinum Iridium Wire Pt90/Ir10 is widely used by medical device manufacturers for:
Radiopaque Marker Bands on diagnostic and therapeutic catheters (coronary, peripheral, neurovascular).
Guidewires and Delivery Systems in endovascular and interventional radiology procedures.
Catheter Components requiring clear imaging under fluoroscopy during minimally invasive surgery.
Electrodes and Sensors in cardiac rhythm management, neuromodulation, and electrophysiological devices.
Stent Delivery Systems and Balloon Catheters for precise placement in vascular interventions.
Other Minimally Invasive Devices such as embolization tools, biopsy instruments, and implantable components needing high visibility and biocompatibility.
