|Condition or disease||Intervention/treatment||Phase|
|Carotid Artery Stenosis||Device: Roadsaver™ Carotid Artery Stent Device Device: Nanoparasol® Embolic Protection System||Not Applicable|
A total of 295 patients will be enrolled for this study. All potential patients being considered for the study should have been diagnosed with significant carotid artery stenosis and be considered a high perioperative risk for carotid endarterectomy.
Patients will be evaluated through screening, pre-procedure, index procedure, post-procedure. Follow-up visits will be completed at 30 days, 6 months, and 12, 24, and 36 months post-procedure.

To evaluate the safety and effectiveness of MicroVention, Inc. Roadsaver™ Carotid Stent System used in conjunction with the Nanoparasol® embolic protection system for the treatment of carotid artery stenosis in patients with elevated risk for adverse events following carotid endarterectomy.
Device: Roadsaver™ Carotid Artery Stent Device
The Roadsaver™ carotid artery stent system is indicated for use in patients with significant atherosclerotic disease of the carotid arteries.
Device: Nanoparasol® Embolic Protection System
The Nanoparasol® embolic protection system is indicated for use with a guidewire to contain and remove embolic material (thrombus/debris) while performing angioplasty and stenting procedures in carotid arteries.
