ST elevation myocardial infarction (STEMI)

heart attack

stent

a small mesh tube that's used to treat narrow or weak arteries

a tube like device that is inserted into a blocked vessel during an angiogram 

in some cases of bowel blockage, a doctor puts expandable metal tubes called stents in your large intestine. A stent holds your intestine open to allow its contents to move forward. This helps your bowels to work better.

stent insertion

the doctor will insert a tiny, flexible plastic tube called a catheter through an artery in our groin, leg, or arm. A special dye is injected so blood flow through the arteries is visible on the TV monitors. The doctor moves a balloon catheter, and then a stent, to the site of the blockage. The balloon is inflated and stretched wide against the artery walls, which opens the blockage.  Then the balloon is deflated and taken out, leaving the stent in place.
