Stents are small, mesh-like tubes made of metal or plastic that are inserted into narrowed or blocked passageways in the body to keep them open. These are majorly used in arteries to treat conditions where plaque buildup restricts blood flow to the heart. These can also be used in esophagus, ureters, or bile ducts. Coronary stent is the majorly used stent inserted during angioplasty. A catheter with a balloon on its tip is threaded through the blood vessels to the blockage area. The balloon is inflated once it is in place. This expands the stent and presses the plaque against the artery walls. The balloon is then deflated and removed, keeping the stent in place to keep the artery open.
Bioabsorbable stents, drug-eluting stents, and bare-metal stents are commonly used stents by the surgeons. Bioabsorbable stents dissolve over time after the artery heals. These minimize long-term complications. Drug-eluting stents are coated with medications that are slowly released to prevent the formation of scar tissue inside the artery. This reduces the risk of restenosis. Bare-metal stents are simple metal stents without any coating. These pose a relatively high risk of restenosis or re-narrowing of the artery.
The global stent market is experiencing rapid growth owing to an increase in prevalence of cardiovascular diseases. There is an increase in the number of people experiencing heart-related complications owing to sedentary lifestyles, an increase in rates of obesity, and adoption of unhealthy diets. This increases the prevalence of cardiovascular diseases, which boosts the demand for stents. In addition, the surge in aging populations and rise in demand for minimally invasive procedures also boost market growth. Stents offer an alternative to open-heart surgery. This shortens the hospital stay and lowers recovery time. This factor, thus, fosters the growth of the market. Moreover, emerging technologies such as bioresorbable vascular scaffolds and smart stents with embedded sensors are opportunistic for the growth of the stent market in the upcoming years. According to the report published by Allied Market Research, the global stents market was valued at $11,749.4 million in 2020. The industry is estimated to reach $19,767.5 million by 2030. The sector is anticipated to experience growth at a CAGR of 5.6% from 2021 to 2030.
Developments
One of the most significant advancements in the stem industry is the introduction of drug-eluting stents. Early-generation drug-eluting stents help reduce restenosis rates compared to bare-metal stents. The ones with advanced technologies offer safety and efficacy as well. Modern drug-eluting stents come with thinner struts, biocompatible polymers, and more precise drug delivery mechanisms. These help lower incidences of thrombosis and restenosis.
The introduction of polymer-free stents is another notable development in the stent market. These stents help release drugs without using polymer carriers and reduce inflammation. These stents are used for patients who are unable to tolerate long-term dual antiplatelet therapy. Another innovation in this field is the introduction of smart stents which have integrated sensors that can monitor blood pressure or blood flow and enable remote monitoring.
