In the late 1980s, a fortuitous observation by cardiologist Julio Palmaz and radiologist Richard Schatz led to the development of this life-saving medical device. While studying the use of balloon angioplasty to open narrowed arteries, they noticed that the artery walls tended to collapse or re-narrow after the procedure. To address this issue, Palmaz designed a tubular scaffold made of stainless steel mesh that could be implanted in the arteries to keep them open. The first successful implantation of a coronary stent took place in 1986. This paved the way for a less invasive and more effective treatment option for patients with coronary artery disease. Over the years, stent technology has advanced significantly, with the introduction of drug-eluting stents that release medications to prevent restenosis.
