He is thought to have coined the term "stent" in 1917 to describe his use of a dental impression compound invented in 1856 by the English dentist Charles Stent (1807–1885) to create a form for facial reconstruction. The term "stent" was later extended to mean a device to expand constricted tubes of body tissue. He was a one time Dutch Chess
Drug-eluting stent Drug-eluting stent A drug-eluting stent (DES) is a peripheral or coronary stent (a scaffold) placed into narrowed, diseased peripheral or coronary arteries that slowly releases a drug to block cell proliferation. This prevents fibrosis that, together with clots (thrombi), could otherwise block the stented artery, a process called restenosis. The stent is usually placed within the peripheral or coronary artery by an interventional cardiologist or interventional radiologist during an angioplasty procedure. Drug-eluting stents in current clinical use were approved by the FDA after clinical trials showed they were statistically superior to bare-metal stents for the treatment of native coronary artery
