A stent is generally placed inside a blood vessel to prevent or overcome a blockage. A bioabsorbable stent is simply able to be absorbed by the body.The United States Food and Drug Administration on July 5, 2016, announced the approval for the first evercompletely absorbable stent for treating coronary artery disease. Coronary heart disease develops in a person when blockages mostly made up of cholesterol; build up in the coronary arteries, resulting in a decreased blood flow to the heart.
This situation is dealt with a procedure called angioplasty, which employs a metal stent to widen the artery. However the bioabsorbable stents can be a great help in this area because they don’t scar the artery as a metal stent does.
Market for Bioabsorbable Stents
According to the reports given by WHO, cardio vascular diseaseis the main cause of deathsworldwide.By 2030 more than 23 million people all over the world will die annually from it. With the increase in the occurrence of cardiovascular disease, less risk of complications associated with bioabsorbable stents will be the main factor for the growth of bioabsorbable stents’ market.
The global market for bioabsorbable stents was estimated at USD 0.40 Billion in 2016 and is expected to reachUSD 2.44 Billion by 2021 rising at a CAGR of 42.5% during this period. The driving factor for the market for bioabsorbable stents is rapidly increasing risk of coronary and peripheral artery diseases. The only factor in which may decelerate the growth of the market is the high cost of the procedure.
Coronary artery disease, which affects around 15 million people in the United States and is a leading cause of death worldwide, can be treated with bioabsorbable stents. Because after the blockagehas been dissolved instead of causing a scar tissue like a metal stent this stent is completely absorbed. A permanent metal stent can cause the artery to narrow (also called restenosis) due to the scar, but that problem is resolved with bioabsorbable stents. These are fabricated from a biodegradable polymer known aspoly (L-lactide). The body itself can get rid of it, after some time, only leaving behind a fewplatinum markers deep inside the arterial walls, which can help cardiologists find out where the bioabsorbable stentwas originally positioned. However with bioabsorbable stents are more expensive than durable or permanent metal stents.
Bioabsorbable stents do offer a better treatment for patients who are supposed to go through angioplasty, but it is not to be used on patients who are allergic to the constituents used in the device, such as poly(L-lactide) or platinum. It is also not advisable to those who are unwilling to take prolonged aspirin therapy.
