ASTM International has released a new standard covering a high-strength alloy that could be used in cardiovascular stents as well as in trauma, spinal and maxillofacial implants. The specification for the new standard was created by ASTM International’s committee on medical and surgical materials and devices (F04).

Known as F3273, the standard specifies the chemical, mechanical, and metallurgical requirements for ‘wrought molybdenum-47.5 rhenium alloy.’ It is believed that this material could be of interest to both regulatory bodies and consumers for its biocompatibility, making it ideal for medical/surgical use. Because it does not require elements such as nickel, chromium or cobalt, it is less likely to cause allergic reactions in patients.

“This Powder Metallurgy alloy has a good combination of high strength and high ductility when compared to other metallic implant materials,” stated John Disegi, an ASTM International member and consultant at Advanced Biomaterial Consulting LLC. He noted that these properties may allow product engineers to ‘downsize’ various existing implants.

The new standard will be highlighted at the North American Spine Society meeting, October 25-28, in Orlando, Florida, USA.
