Stent out. Others attribute the noun "stent" to Jan F. Esser, a Dutch plastic surgeon who in 1916 used the word to describe a dental impression compound invented in 1856 by the English dentist Charles Stent (1807–1885), whom Esser employed to craft a form for facial reconstruction. The full account is described in the "Journal of the History of Dentistry". According to the author, from the use of Stent's compound as a support for facial tissues evolved the use of a stent to hold open various bodily structures. The first (self-expanding) "stents" used in medical practice in 1986 by Ulrich Sigwart
Drug-eluting stent of a new endothelial layer over the new stent to inhibit clot formation. Endothelialization is a hallmark of vascular healing and is important for the prevention of thrombus formation. Lack of healing caused by antiproliferative drugs can make the stent an exposed surface on which a clot, sometimes life-threatening, can form. For drug-eluting stents (which, by design, delay formation of a new endothelium cover over the stent), the incidence of clot formation within the stent may persist for a longer period of time, perhaps as long as five years after treatment. Drug-eluting stents have been associated with delayed arterial healing
