Overview of Platinum Iridium Medical Tube
Our ASTM B684 Platinum Iridium medical tubes deliver exceptional performance in neurostimulation and implantable medical devices. Manufactured from high-purity platinum-iridium alloys (commonly 90Pt/10Ir or 80Pt/20Ir), these precision medical tubes combine outstanding electrical conductivity, mechanical durability, and biocompatibility. They are ideal for long-term implantation in neuromodulation systems, offering low impedance, high charge transfer capacity, and excellent resistance to bodily fluids. Whether used in deep brain stimulation (DBS) leads, spinal cord stimulation (SCS) electrodes, or custom hypotube components, these biocompatible tubes ensure reliable signal transmission and structural integrity in demanding biomedical environments.

FAQs About Medical Grade Platinum Iridium (Pt90/Ir10) Tubes
Q: What does ASTM B684 compliance mean for medical tubing?
A: ASTM B684 specifies high-purity platinum-iridium alloys (such as 90/10 or 80/20 Pt/Ir) for electrical contact materials. When applied to medical tubes, it guarantees consistent composition, excellent conductivity, and reliability for neurostimulation leads and implantable devices.
Q: Why is platinum iridium the preferred alloy for neurostimulation electrodes and tubing?
A: Platinum iridium offers unmatched biocompatibility, corrosion resistance in bodily fluids, low impedance, high charge injection capacity, and added mechanical strength from iridium—making it superior for long-term neural stimulation compared to stainless steel or other alloys.
Q: Are these platinum iridium medical tubes suitable for chronic implantation?
A: Yes. They are widely used and FDA-cleared in many neurostimulation systems (DBS, SCS, etc.) due to their proven long-term stability, minimal tissue reaction, and resistance to degradation.
Q: What customization options are available for the tubing?
A: We provide various outer/inner diameters, wall thicknesses, lengths, alloy ratios, surface finishes, and secondary operations (e.g., laser cutting, electropolishing) to match your specific neurostimulation lead or implantable device requirements.
Q: Is the platinum iridium tubing MRI compatible?
A: Most configurations are MRI conditional. Always verify compatibility with the final assembled neurostimulation device labeling and consult regulatory guidelines for your specific implantable application.
