Meaning of stent by John Rene Plaut

Eponymous STENT derived from the surname of Charles Thomas Stent, who patented (1856) a thermoplastic material, called Stent paste, to make dental impressions; vascular stent consisting of a metal mesh (coated with a releasing drug that prevents future blockages) that expands, once a catheter has been inserted into the damaged blood vessel through an incision in the artery at arm, wrist or groin, a clinical procedure called angioplasty. The stent is usually placed in coronary arteries that have suffered injuries and where there is obstruction of blood circulation with danger of heart attack, or as a result of one already occurred. The most common cause of the damage is the accumulation of cholesterol in the arterial walls. The stent, by extension, can be any inflatable mesh installed in a duct, such as the renal for example.
