A Multicenter, Single-arm, Pivotal Study to Evaluate Acute Device and Technical Success of the CGuard Prime Carotid Stent System (80cm) When Used in Conjunction With the FDA-cleared ENROUTE Transcarotid Neuroprotection System (NPS) in Patients at High Risk for Adverse Events From Carotid Endarterectomy Undergoing Carotid Artery Stenting Via the Transcarotid Artery Revascularization (TCAR) Approach.

简要总结
The objective of this study is to evaluate acute device and technical success of the CGuard Prime™ Carotid Stent System (80cm) when used in conjunction with the Enroute NPS during Transcarotid Artery Revascularization procedures in the treatment of carotid artery stenosis in spatients at high risk for adverse events from carotid endarterectomy.
详细描述
This study is a prospective, multi-center, single arm pivotal study. The study shall not be blinded prior to, during or following the procedure. Patients undergoing transcarotid artery revascularization will be screened against the study inclusion/exclusion criteria. If the patient meets study eligibility requirements, they shall be invited to participate, provide informed consent and shall subsequently be assigned a study ID number.
Enrollment will be a minimum of 50 evaluable pivotal patients. A maximum of 20% of patients will be enrolled at any single site. The total enrollment accounts for an estimate that up to 2 patients will exit the study prior to the 30-day primary endpoint assessment.
An additional roll-in cohort of up to 2 patients per primary physician operator at each study site may also be accrued (maximum of 24 roll-in patients total, assuming one primary physician operator per site).
This study does not duplicate any current knowledge existing today on use of the CGuard Prime™ 80 used in conjunction with the ENROUTE NPS in the United States.

结局指标
主要结局
Acute device success
时间窗: From enrollment to end of follow-up at 1 year
Successful insertion of the delivery system, successful deployment of the CGuard Prime™ 80 stent, and successful retraction of the delivery system when used in conjunction with the FDA-cleared ENROUTE NPS during a TCAR procedure.
Technical success
时间窗: From enrollment to end of follow-up at 1 year
Technical Success Rate is defined as the number of patients with at least one CGuard Prime™ 80 device successfully delivered and deployed with final residual diameter stenosis \< 30% following final post-balloon dilatation (if performed) divided by the total number of patients where CGuard Prime™ 80 device deployment was attempted when used in conjunction with the FDA-cleared ENROUTE NPS during a TCAR procedure.
