MEDICAL PLATINUM PLATING

Catheters

Catheters are one of the most common medical devices used today for delivering medication to specific areas, performing minimally invasive surgical procedures. Most catheters can benefit from using platinum in different ways. Platinum can be used as electrode material in Electrophysiology Catheters to monitor and measure the activity of certain cardiac muscles, or to ablate and stimulate anatomy within the body. Platinum guide-wire can also be used to guide and maneuver catheters to certain treatment sites. Doctors can use a Platinum marker band at the distal end of a catheter under radiographic imaging to see and operate on an area without an invasive incision.

Cardiac Implants

Pacemaker components, heart valve splices, and coronary stents often times include Platinum components such as marker bands, leads, and electrodes. Due to its high biocompatibility, using Platinum reduces the risk that the body will reject an implant. Platinum’s ductility serves as the perfect solution for making the extremely small wires that connect all the tiny electronics within a pacemaker.

Neuromodulation Devices

Platinum can be used for the external structures of certain devices such as neuromodulation devices. These devices are developed to send electrical signals to the central nervous system. This helps treat and manage chronic neurological conditions like Parkinson’s disease. Platinum allows for electrical conductivity and a metallic layer on the external structure of the device.

Why Platinum Matters in Medical Devices

Platinum offers a unique combination of properties that make it especially valuable for medical device applications:

• Biocompatibility: Platinum is highly inert and does not cause adverse reactions when in contact with tissues or bodily fluids, making it suitable for implantable applications.

• Corrosion resistance: Its resistance to corrosion in aggressive environments, including sterilization and body chemistry, enhances device longevity.

• Electrical conductivity: Platinum’s stable, high conductivity makes it well-suited for electrodes and signal-transmitting components.

• MRI compatibility: Platinum’s non-magnetic characteristics help support MRI-safe components where imaging needs must be balanced with performance.

• Radiopacity: Dense atomic structure improves visibility under X-ray and fluoroscopy, which is critical for implant placement and monitoring.

Specialized Capabilities for Complex Geometries

Many medical device components feature intricate designs, fine features, and challenging surface profiles. ProPlate®’s proprietary platinum electroplating techniques are engineered to offer:

• Uniform surface coverage even on microscopic features

• High throwing power for deep recesses and internal channels

• Controlled thickness and tolerance for precision instrumentation

• Selective plating options where masking or functional zones are needed

These capabilities ensure consistent performance and meet the mechanical, electrical, and regulatory requirements of complex medical assemblies.

Common Medical Platinum Plating Applications

Platinum plating enhances performance in a variety of medical device categories:

• Implantable electrodes (e.g., pacemaker and defibrillator contacts)

• Neurostimulation and electrophysiology sensors

• MRI-compatible components and leads

• Catheter electrodes and signal paths for electrophysiology mapping

• Radiopaque markers for interventional devices

• Diagnostic sensors exposed to biological fluids

These coatings are selected when the highest levels of stability, longevity, and patient safety are required.
