Jan F. Esser Champion, winning the Dutch Championship in a play-off match for the title against Rudolf Loman in 1913. Jan F. Esser Johannes "Jan" Fredericus Samuel Esser (13 October 1877 in Leiden – 9 August 1946 in Chicago) was a Dutch plastic surgeon who pioneered innovative methods of reconstructive surgery on soldiers wounded in the First World War. 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
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
