The vascular stent is metal or plastic tube inserted into the lumen of an anatomic vessel to keep the passageway open. The application of stents in removing the blockage of arteries and veins is increasing, such as coronary stents, peripheral stents, carotid stents, renal artery stents, femoral stents, iliac stents, evar stent grafts, abdominal aortic aneurysm, and thoracic aortic aneurysm.
Recently, this Vascular Stent technology is widely applied in clinical practice and has become the best effective method for the treatment of myocardial infarction and other cardiovascular diseases. Increase in a number of cardiovascular and cerebrovascular diseases have developed the most serious threats to human health and life expectancy. For instance, it was estimated that approximately 20% of all strokes are caused by carotid artery disease (Stroke U.K.). Similarly, it was estimated that approximately 1 of every 13 Americans aged above 18 years and older have been diagnosed with Coronary artery disease (CAD).
Increasing heart diseases, the growing prevalence of vascular disease, obesity, increasing geriatric population, and changing lifestyle are the factors which are contributing to the increasing demand for vascular stents. Moreover, insertion of the vascular stent is the most effective and rapid method to cure cardiovascular and cerebrovascular diseases, by preserving the patency of the blood flow. Some of the manufactures of vascular stent market include Medtronic, plc. (Ireland), Abbott Laboratories (U.S.), Boston Scientific Corporation (U.S.), BIOTRONIK SE & Co. KG (Germany), B. Braun Melsungen AG (Germany), Terumo Corporation (Japan), STENTYS SA (France), MicroPort Scientific Corporation (China), and Meril Life Sciences Pvt. Ltd.
On January 31, 2018, Bentley launched BeGraft peripheral plus stent graft System in Europe, BeGraft peripheral plus is a covered, balloon expandable stent indicated for renal and iliac arteries, which restores and improves the patency and treatment of aneurysms, acute perforations, and ruptures of the iliac and renal arteries.
