What is a stent?
A stent is a small tube that is an essential part of an angioplasty procedure. It is a tool made from wire and mesh, which enables the surgeon to prop open the coronary artery and leave the stent in place within the body.
The coronary artery is the nerve, which feeds oxygen to the heart. A stroke or attack usually happens when the supply is cut off due to the narrowing of the arteries. This happens due to the build-up of fatty acids, also known as plaque.
The angioplasty stent thus reduces further chances of heart attack by widening the arteries and allowing the blood to flow through freely.
A stent is usually inserted into the artery by using a catheter, which the stent locks in place after expansion. The expansion reduces the plaque which has been blocking the vessel. After the lockdown, the balloon catheter is deflated and taken out, as the stent remains inside.
So what is a stent made of?
It is natural to be curious about the components of a wire which is going to stay inside your body for a while. In most cases, a stent is made of wire and mesh, some can even be made of fabric. However, some of the stents are made of metals and materials that may dissolve in your body over a specific period of time. These stents are also layered with medicines.
While inserting a stent, the procedure undertaken is called angioplasty.
Importance of a stent
After asking, “what is a stent?” and knowing the components from which it is made, the next question should be on the importance of stent. What is it that makes a tiny wire play such a vital role in saving one of the most important organs in the human body? Let’s find out.
Stents are used to expand the artery passage which becomes narrow due to the formation of plaque: a fatty material made of cholesterol and other substances, which attaches to the vessel’s walls.
