stent

(Science: equipment) A tube made of metal or plastic that is inserted into a vessel or passage to keep the lumen open and prevent closure due to a stricture or external compression.

stents are commonly used to keep blood vessels open in the coronary arteries, into the oesophagus for strictures or cancer, the ureters to maintain drainage from the kidneys, or the bile duct for pancreatic cancer or cholangiocarcinoma.

The stents are usually inserted under radiological guidance and can be inserted percutaneously.
