In a December 2015 blog post, I quoted a report by Technavio stating that bioresorbable coronary stents would be a key technology to watch over the next five years. Those in clinical development are either made of lactic acid polymers or use magnesium-based scaffolds, which break down naturally. More than a dozen companies have programs developing such products, which Forbes recently described as “the science-fiction-like promise to return damaged arteries to their natural state.” Two of these devices have CE mark, and both are working toward FDA clearance.
