a coronary artery stent is what you are talking about, the irony is of it that when the person who invented this made it got a failing grade... crazy right?
Hello there and welcome to Brainly!
A stent is typically used to correct an artery that is partially blocked. The stent would be attached to a catheter and would enter your body through either your arms or legs, and would be guided up towards the blockage. When at the blockage, a balloon would be inflated to open up the blocked vessels, and then the stent would be placed to keep the artery open.
