Medical Precious Metals

Implantable and minimally invasive device applications require materials that, at a minimum, possess structural integrity and biocompatibility. As engineers push the limits of device functionality, PI Medical strives to stay ahead of the curve to provide materials with secondary characteristics that go beyond mere biocompatibility.

Precious metals have several desirable properties that make them suitable for use in a wide range of medical related applications.  These properties include, but are not limited to: biocompatibility, electrical conductivity, mechanical durability, corrosion resistance, and radiopacity. 

The manufacturability and diverse processing capabilities of precious metals allow them to be formed into an array of different geometries and sizes for use in medical devices.  Several application areas that utilize precious metals include stents, catheter ablation, angioplasty, endovascular embolization, pacemakers, defibrillators, and hearing devices such as the cochlear implant.

Studies have found that precious metals and their alloys possess chemical, physical, and mechanical properties that make the material uniquely suitable for a variety of medical applications where biocompatibility may be required. Prince & Izant Medical regularly supplies materials in a variety of forms to manufacturers of implantable medical devices. As with all applications, the device  manufacturer alone can determine which products are most suitable for their particular medical device. Prince & Izant Medical is equipped to provide additional testing services if requested (additional fees may apply).

Medical Brazing Alloys (MedBrazeTM)

For many of the same benefits mentioned above, precious metal-based alloys are also utilized for the brazing of medical applications.  Artificial pacemakers and other devices for cardiac rhythm management often utilize pure gold for brazing of platinum-iridium electronic leads.  The high conductivity, favorable wetting and relatively low melting range of gold and gold-based alloys make them a preferred filler metal for brazing a range of different precious metals.  Other medical products joined with precious metals include electrosurgical tools, orthopedics and medical imaging devices
