Primary Outcome Measures:
  • Number of Participants Who Experienced a 30-Day Major Adverse Event (MAE) [ Time Frame: 30 Days ]
    30-day major adverse events (MAEs) are defined as all deaths, strokes, and myocardial infarctions (MIs) that occur within 0-30 days post-procedure.

  • Number of Participants Who Experienced a 12-Month Major Adverse Event (MAE) [ Time Frame: 12 Months ]
    12-month major adverse events (MAEs) are defined as all deaths, strokes, and myocardial infarctions (MIs) that occur within 0-30 days post-procedure (see 30-Day MAE above), and ipsilateral stroke events that occur within 31-365 days post-procedure.


Enrollment: 298
Study Start Date: May 2007
Study Completion Date: July 2009
Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: NexStent Carotid Stent System (Monorail Delivery System)
    Self-expanding carotid stent for treating patients at high risk for adverse events from carotid endarterectomy who require carotid revascularization.
    Device: FilterWire EZ™ Embolic Protection System
    Used as a guide wire and embolic protection system to contain and remove embolic material (thrombus/debris) while performing angioplasty and stenting procedures in coronary saphenous vein bypass grafts and carotid arteries.
Detailed Description:
The SONOMA Registry will enroll approximately 300 subjects at a maximum at 78 study centers.
