?:definition
  • Vascular stents designed for deployment into the intracranial arteries to enlarge the lumen of an intracranial artery diameter. These stents have a self-expanding design with flexible cells to improve conformability in curved and tapered vessels; the stents support the vessel by providing an outward radial force intended to minimize vessel recoil. Intracranial artery stents are typically delivered following percutaneous transluminal angioplasty (PTA) performed with a balloon catheter that dilates the stenotic portion of intracranial arteries prior to stenting. Intracranial artery vascular stents are mainly used for the purpose of improving long term intracranial perfusion in patients with intracranial atherosclerotic disease, refractory to medical therapy.
