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 and the prevalence of latent thrombus after five years, suggesting patients may continue to be at risk for stent thrombosis for an extended period of time. Though less frequent with drug-eluting stents, neointimal proliferation can still occur in DES and cause restenosis. Stent occlusion because of thrombosis may occur during the procedure, in the following days, or later. The presence of thrombi around the stent may, in turn, affect the drug-eluting performance of the stent. Treatment with the antiplatelet drugs aspirin and clopidogrel appears to be the most important factor reducing this risk of thrombosis, and early cessation of one
