Brief Summary:
The primary objective of this study is to assess the outcomes of stenting with distal protection in the treatment of obstructive carotid artery disease. The devices to be utilized are the Cordis PRECISE® Nitinol Stent Systems (5.5F and 6F) and the Cordis ANGIOGUARD™ XP Emboli Capture Guidewire (ECGW).

Primary Outcome Measures :
  1. Any death, stroke or any MI [ Time Frame: up to 30-days post-procedure ]

Secondary Outcome Measures :
  1. Assess the consistency of MAE rates of stenting with distal protection in the treatment of obstructive carotid artery disease among high, medium and low volume centers with physicians who have validated CASES training levels of 1, 2, 2P or 3 [ Time Frame: 30 days ]
  2. Assess the real-world cost-effectiveness of carotid artery stenting in subjects enrolled [ Time Frame: Every follow-up where a PRO instrument QoL was assessed ]
  3. Estimate MAE (death and ipsilateral stroke) rate in a subset of the planned total enrollment [ Time Frame: 1 year ]
