The origin of the word Stent

In 1856, the English dentist Charles Stent developed a thermoplastic-like material for taking impressions of toothless mouths. This "Stent mass" was later used as a device or mould for keeping a skin graft in place; it was also used to provide support for anastomosis. A hundred years after the inventor's death in 1885, the word stent has been adopted all over the world in interventional radiology but today it is understood to mean percutaneous tubular structures that induce or maintain lumen patency. The true origin of the word stent is not found in many dictionaries. In most references, the wrong dentist is given credit for the discovery. Dictionaries also refer to the obsolete English and Scottish words stent and stint which mean, among other things, "to extend". The true origin of the word is therefore somewhat unclear.
