Stents, Vascular, Coronary, Self-Expanding
Definition : Coronary vascular stents that expand by themselves after deployment through an appropriate stent delivery system, applying a constant radial pressure to the artery walls. These devices consist either of compressed metallic stents that open by themselves as soon as they are released or of shape-memory stents manufactured from an alloy combining nickel and titanium (i.e., nitinol) that expands in response to body temperature. Some stents include radiopaque markers for accurate stent positioning. Self-expandable coronary stents are intended to form a scaffold that holds the coronary arteries open to prevent restenosis caused by vessel recoil and/or remodeling.
