Stents, Vascular

Definition : Stents designed for deployment into the vessels to provide support for and/or maintain patency within the vasculature. These devices typically consist of a metallic or synthetic scaffolding (e.g., mesh, coil, slotted tube) and are available in several different shapes (e.g., straight, bent, bifurcated) to adapt to particular sections of the vasculature or to prevent migration. Some metallic stents are either balloon expandable or self-expanding; their surface may be coated to add special capabilities to the stent (e.g., to reduce protein and/or platelet adhesion, to elute drugs). Vascular stents are mostly used to reduce vascular recoil or narrowing (i.e., restenosis) of the vessels, especially in the coronary arteries.
