ASM International Honors NETL Work on Platinum-Chromium Alloy for Coronary Stents
For their work on the development, transfer, and successful commercialization of a novel platinum-chromium alloy used in next-generation coronary stents, scientists at the National Energy Technology Laboratory (NETL), and their colleagues, have been selected to receive a 2015 ASM Engineering Materials Achievement Award from the materials science and engineering society ASM International.
NETL’s Paul Jablonski, Paul Turner, Edward Argetsinger, and Jeffrey Hansen developed the alloy in collaboration with researchers at Boston Scientific Corporation. It is the first stainless steel formulation for stents with a significant concentration of platinum, making it easier for coronary specialists to see the stent on x-ray during placement and expansion. The alloy also increases the stents’ corrosive resistance, strength, and flexibility.
Stents made from the alloy benefit patients by shortening recovery time and avoiding follow-on procedures and more invasive surgery, which reduces healthcare costs. Since their commercial introduction in 2010, the stents have generated more than $6 billion in sales and captured a 25 percent U.S. share and a significant global share of the coronary stent market.
Engineered and manufactured in the United States, the stent series has created 450 sustainable domestic jobs. Carpenter Specialty Alloys, Accellent, and Minitubes Corporation also played a role in the chain from laboratory to market that made the alloy and subsequent stents a success.
The ASM Engineering Materials Achievement Award has recognized outstanding materials science advancements since its inception in 1969. NETL will be presented with the award at an awards banquet during the 2015 Materials Science and Technology meeting in Columbus, Ohio.
Each month, NETL and the Energy Department’s other national labs showcase their work in various areas that benefit the nation. This story is part of a series on how the national labs are developing custom materials with specific properties that are meeting the demands of the scientific community and revolutionizing industry.
