Jan F. Esser 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 mean a device to expand constricted tubes of body tissue. He was a one time Dutch Chess
Drug-eluting stent of thrombosis was shown after the first year, compared to bare-metal stents. Late stent thrombosis often causes myocardial infarction and sometimes death. In other analyses, the late thrombosis risk is offset by drug-eluting stents' markedly reduced risk of restenosis and its complications including myocardial infarction. A meta-analysis concluded the mortality risk associated with drug-eluting and bare-metal stents is similar. Drug-eluting stents generally consist of three parts - the stent platform, a polymer coating that binds the drug to the stent and releases drug (although stents have been tested that do without a coating), and the drug. The stent platform itself
