Peripheral vascular disease is a disorder of blood circulation which causes narrowing or blockage of blood vessels outside the heart and the brain. Peripheral vascular disease are also known as claudication, intermittent claudication, critical limb-threatening ischemia, and arteriosclerosis obliterans. It can be classified into functional and organic; functional peripheral vascular disease either widens or narrows the vessels which decreases the blood flow while organic peripheral vascular disease changes the structure of the blood vessels. On the other hand, peripheral artery disease is caused by buildup of fatty plaque in arteries.
Peripheral vascular stents, also known as intravascular stents or endovascular stents, are small, expandable tubes that treat narrowed arteries in the body. In the recent years, there has been a rise in the number of patients with peripheral artery disease, primarily due to aging of the population, change in lifestyle habits, pollution, smoking, and others. All of these factors contribute to the high adoption of peripheral vascular stents. Some significant properties of the peripheral vascular stents include simple and easy-to-use delivery system, minimal foreshortening in deployment, precise placement, resistance to corrosion, and durable.
Prevention and treatment of peripheral artery disease are being conducted even in low- and medium economies which is expected to escalate the use of peripheral vascular stents. Rising prevalence of patients with peripheral artery disease is also likely to increase the requirement for peripheral vascular stents during surgeries as it has shown improved life expectancies. The effectiveness of peripheral vascular intervention has encouraged many outpatients in developed countries coupled with modification in reimbursement policies. High success rate of endovascular surgeries has further broadened the options for treating peripheral artery disease which is likely to increase the adoption of peripheral vascular stents in the coming years.
Endovascular stents lower the risk that usually prevails in the conventional open surgical treatment. Furthermore, technological advancement and new innovations in techniques improved peripheral vascular surgeries to a greater extent. There has been an increase in the use of balloon and self-expendable peripheral vascular stents along with new technologies such as drug eluting stents. Through various research and developments, drug eluting stents are being created to reduce the number of recurrence of peripheral artery disease. Many stents manufacturers are focusing on enhancing the design of peripheral stents and drug delivery for treatment and prevention of these diseases. Additionally, medical companies are making major investments for the development of effective peripheral stents
