What Is a Stent?


– A stent is a scaffolding device. Its pedigree is a metallic tube. And then, the bulk of
the metal is laser-etched and it becomes a tube which
has multiple side windows. So it looks like a spring. It’s then crimped down on a balloon and then, it’s advanced into an artery that needs support from inside. And then we expand the balloon. Sticking the stent which becomes a tubular structure then,
into the vessel wall. So here, it prevents
the wall or the tissue that’s blocking the artery from collapsing back into the artery. So essentially, creating,
it’s like reinforcing a tunnel with stainless steel rings
from the inside, so to say. And that has been used for
blocked arteries in the heart. We use stents in blocked
arteries in the legs, blocked arteries in the kidneys. We have used stents for the
carotid arteries for strokes. And the stents can then also be used now as scaffolding devices or structures that would actually anchor as anchoring devices for stent valves. So, stents are a generic, new
technology that we’ve used very widely and in
multiple different ways.
