Brief summary

The study objective is to evaluate real world usage of the ENROUTE Transcarotid Stent when used with the ENROUTE Transcarotid Neuroprotection System in patients at standard risk for adverse events from carotid endarterectomy

Detailed description

This is an open label, single arm, multi-center post-approval study for the treatment of patients at standard risk for adverse events from carotid endarterectomy who require carotid revascularization and who are eligible for treatment using the ENROUTE Transcarotid Stent System and the ENROUTE Transcarotid Neuroprotection System. The study will enroll a maximum of 400 patients treated per protocol at 30-60 sites in the United States.

Interventions

Carotid artery revascularization treated with the FDA-cleared ENROUTE Transcarotid NPS in conjunction with the FDA-approved ENROUTE Transcarotid Stent

Inclusion criteria

1. Patient has a discrete lesion located in the internal carotid artery (ICA) with or without involvement of the contiguous common carotid artery (CCA) determined by duplex ultrasound, CT/CTA, MR/MRA or angiography. 2. Patient must meet one of the following criteria regarding neurological symptom status and degree of stenosis: Symptomatic: ≥70% stenosis of the common or internal carotid artery by ultrasound or ≥50% stenosis of the common or internal carotid artery by angiogram OR Asymptomatic: ≥70% stenosis of the common or internal carotid artery by ultrasound or ≥60% stenosis of the common or internal carotid artery by angiogram 3. Target vessel must meet all requirements for ENROUTE Transcarotid Neuroprotection System and ENROUTE Stent System (refer to IFU for requirements). 4. Patient is ≥18 and \<80 years of age. 5. Patient understands the nature of the procedure and has provided a signed informed consent using a form that has been reviewed and approved by the Institutional Review Board of the respective clinical site prior to the study procedure. This will be obtained prior to participation in the study. 6. Patient is willing to comply with the protocol requirements and return to the treatment center for all required clinical evaluations.

Exclusion criteria

1. Patient meets any of the surgical high-risk criteria listed below. 1. Anatomic high risk
