About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patient is ≥ 18 years and < 80 years of age.

Patient is willing and able to provide appropriate study-specific informed consent, follow protocol procedures, and comply with follow-up visit requirements.

Symptomatic carotid stenosis ≥ 50%. Symptomatic is defined as amaurosis fugax, transient ischemia attack (TIA) or stroke within the last 6 months ipsilateral to the side of the stenosis Or

Asymptomatic carotid stenosis ≥ 80%

Disqualifiers

Patient had or will have an interventional procedure or surgery of the carotid, coronary or peripheral arteries within 30 days before or after the index carotid procedure.

Patient had or will have open heart surgery or valvular intervention (percutaneous or surgical), or any major operation, within 30 days before or after the index carotid procedure.

Vascular anatomy that would preclude safe sheath insertion or deliverability of stent

Patient had a previously placed stent in the ipsilateral ICA or CCA.

Trial outcomes

Primary outcomes

1

Acute device success

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.

Time frame
From enrollment to end of follow-up at 1 year
2

Technical success

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.

Time frame
From enrollment to end of follow-up at 1 year

Secondary outcomes

1

Procedural success

Acute device success for CGuard PrimeTM 80 Delivery System and Stent without experiencing death, stroke or MI through 30-day post-procedure when used in conjunction with the FDA-cleared ENROUTE NPS during a TCAR procedure.

Time frame
From enrollment to 30-day follow-up
2

Treatment success

Treatment Success Rate is defined as the number of patients who meet CGuard Prime™ 80 Technical Success Rate without experiencing death, stroke or MI through 30-day post-procedure, 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.

Time frame
From enrollment to 30-day follow-up
3

Occurence of Hierarchical Death, Stroke or Myocardial Infarction (DSMI) within 30 days of the procedure

Time frame
From enrollment to 30-day follow-up
4

Hierarchical Death or Stroke rate within 30 days of the procedure

Time frame
From enrollment to 30-day follow-up
