Vascular stents are wire mesh tubular devices deployed into diseased arteries with localised constrictions to prop them open for improved blood flow. Stents are inserted in their collapsed configuration, placed over a balloon catheter and guided to the area of blockage. The balloon is then inflated, expanding the stent holding the artery in its open position. The stent, thus acts as a scaffold, acting as an effective device in treating artery occlusion.
