Detailed Description
A prospective, multicenter single-arm, open label study to evaluate the safety and effectiveness of the Neuroguard IEP® Direct System for the treatment of carotid artery stenosis in subjects at elevated risk for adverse events following carotid endarterectomy (CEA). The Neuroguard IEP Direct System is a 3-in-1 carotid stent delivery system consisting of an angioplasty balloon, an integrated embolic protection device and a nitinol self-expanding stent loaded over the balloon and constrained by an outer sheath. Eligible patients greater than or equal to 20 years of age and less than or equal to 80 years of age, are those who have been diagnosed with either de-novo atherosclerotic or post CEA restenotic lesion(s) in the internal carotid arteries (ICA) or at the carotid bifurcation with greater than or equal to 50% stenosis if symptomatic or greater than or equal to 70% stenosis if asymptomatic.
Symptomatic subjects are defined as having stroke or transient ischemic attack (TIA) in the ipsilateral hemisphere supplied by the target vessel carotid lesion or ipsilateral transient monocular blindness (amaurosis fugax) within 180 days prior to the index procedure.
Subjects will be followed for 30 days post index procedure with additional follow up for subjects having a stroke or cranial nerve injury.

- Subject with intracranial pathology, that in the opinion of the investigator, makes the patient inappropriate for study participation (e.g., arteriovenous malformation, intracranial tumor, microangiopathy or large vessel cerebral vascular disease, etc.) or that would confound the neurological evaluation.
- Angiographic, CT, MR or ultrasound evidence of atherosclerosis of the common carotid artery that would preclude or make difficult safe placement of the sheath and other endovascular devices to the target artery as needed for carotid stenting.
