FLEXIBLE STEEL: A coronary stent is a small, self-expanding metal mesh tube that saves thousands of lives every year by opening blocked arteries and allowing blood to flow freely again.
Jointly developed by the Energy Department's National Energy Technology Lab (@NETL_DOE) and Boston Scientific Corporation Inc. (BSCI), this novel alloy is the first austenitic stainless steel formulation to be produced for the coronary stent industry with a significant concentration of platinum, making it highly visible on x-ray scans. Better visibility means greater ease and precision in placement of the stent inside the patient’s blood vessel.
In addition, the greater yield strength of the alloy allowed the stent’s designers at BSCI to make a thinner, more flexible stent that is more easily threaded through the winding path of the artery without doing damage along the way. This has allowed it to be deployed much smaller vessels in and around the heart.
Since its introduction in 2010, this platinum/chromium technology has become one of the leading stent platforms in the world.
