CGuard Prime Dual Layer Design
CGuard Prime is designed to prevent embolization by securing carotid plaque behind its MicroNet mesh, preventing prolapse through the stent struts while maintaining blood flow to the external carotid artery.
CGuard Prime has the smallest pore size of any approved carotid stent (150-180 μm)*

Stroke and death (S/D) out to 4-years was 6.0% for medical therapy and 2.8% when CAS was added
Absolute difference of 3.2% favoring CAS was significant
Only 31 people with high-grade asymptomatic carotid stenosis needed to be treated to prevent a primary event at 4 years
Note- No primary events happened on the day of the procedure- what is left behind matters!
S/D out to 4-years was 5.3% for medical therapy and 3.7% when CEA was added
Absolute difference of 1.6% favoring CEA was not significant
