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
Coronary stent stent placement. Substantial improvements have been made, including the use of more biocompatible materials, anti-inflammatory drug-eluting stents, resorbable stents, and others. Restenosis can be treated with a reintervention using the same method. The value of stenting in rescuing someone having a heart attack (by immediately alleviating an obstruction) is clearly defined in multiple studies, but studies have failed to find reduction in hard endpoints for stents vs. medical therapy in stable angina patients (see below). The artery-opening stent can temporarily alleviate chest pain, but does not contribute to longevity. The "...vast majority of heart attacks do not originate with obstructions
