Study population

Adults; either gender; requiring percutaneous intervention of an asymptomatic (> 70%) or symptomatic (>50%) internal carotid artery stenosis.

Inclusion criteria

  • Documented stenotic atherosclerotic lesion located at carotid bifurcation and / or proximal internal carotid artery (ICA)
  • Subject is either (A) symptomatic within 6 months of procedure, with an ipsilateral carotid stenosis ≥ 50% by angiography, or (B) asymptomatic with carotid stenosis ≥ 70% by angiography
  • Target lesion can be covered by a single stent of no more than 40 mm in length
  • Target lesion reference vessel diameter (RVD) is 4.0 mm - 7.0mm
  • Sufficient landing zone required for successful deployment of integrated embolic protection filter
  • Willing to comply with all follow-up required study visits
  • Provision of written informed consent before index procedure

Exclusion criteria

Exclusion Criteria:

  • Life expectancy of less than one year
  • An evolving, acute or recent stroke within 14 days of study evaluation
  • Acute myocardial infarction within 72 hours before procedure
  • Known sensitivity to contrast media that cannot be adequately controlled with pre-medication
  • Subject has a total occlusion of target carotid artery
  • Subject has a previously place stent in ipsilateral carotid artery
  • Severe circumferential lesion calcification that may restrict full deployment of carotid stent
  • Presence of filling defect or thrombus in target vessel
  • Presence of "string sign" of target vessel
  • Carotid (intracranial) stenosis located distal to target lesion
  • Greater than 50% stenosis of common carotid artery proximal to target lesion.
  • Known mobile plaque in aortic arch
