Yes, even though it is a small wire, there are various types of stents. From the ones which are coated with drugs to the plain metal ones, there are different types of stents available.
Depending on the pros and cons they offer, along with the risk factors in the patient involved, it is decided which type of stent will be used in angioplasty.
Let’s take a look at the various types of stents:
Drug-Eluting Stent
This stent is coated with a medication that is eluted or released with the aim of preventing scar tissue growth in the lining of the artery. This ensures that the artery passage remains open for a smooth flow of blood.
However, this stent can increase the chances of a blood clot. Also, the healing process is slower, thus, the patients have to adhere to the strict instructions of their doctor.
Bio-engineered Stent
Also known as antibody-coated stent, it neither uses polymer nor any drug. Instead, it helps escalate the healing process by speeding up the artery cell lining, also known as the process of endothelialization.
The antibody coating on this type of stent attracts the bone marrow cells from the body which speeds up the formation of the endothelium. This reduces the risk of blood clots.
