Medical Device Model Stent

This medical device animation illustration was created for a company before the device was made. The medical animation was created for investors and promotion of their new stent.

The origin of the word stent remains unsettled. The verb stenting was used for centuries for the process of stiffening garments (a usage long obsolete, per the Oxford English Dictionary) and some believe this to be the origin. Others attribute the noun stent to Jan F. Esser, a Dutch plastic surgeon who in 1916 used the word to describe a dental impression compound invented in 1856 by the English dentist Charles Stent (1807–1885), which Esser employed to craft a form for facial reconstruction. The full account is described in the Journal of the History of Dentistry.[1] According to the author, from the use of Stent's compound as support for facial tissues grew the eventual use of stent to open various bodily structures. Worth noting though is that the first "stents" used in medical practice were initially called "Wallstents". MEDINOL is the inventor responsible for the original closed cell stent design - a design at the heart of MEDINOL's revolutionary NIR stent, a flexible spring inserted in an artery leading to the heart in a catheretization balloon. The spring is placed on the artery's inner wall and prevents it from collapsing, to facilitate blood flow to the heart.

The main purpose of a stent is to counteract significant decreases in vessel or duct diameter by acutely propping open the conduit by a mechanical scaffold or stent. Stents are often used to alleviate diminished blood flow to organs and extremities beyond an obstruction in order to maintain an adequate delivery of oxygenated blood. Although the most widely known use of stents is in coronary arteries, they are widely used in other natural body conduits, such as central and peripheral arteries and veins, bile ducts, esophagus, colon, trachea or large bronchi, ureters, and urethra.
