New combo device may catch more Stroke-Causing debris during artery stenting

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria： 1. Age 18 years or older; 2. Symptomatic extracranial carotid artery stenosis (occurrence of transient ischemic attack or non-disabling stroke in the ipsilateral carotid territory within the previous 6 months, with stenosis of 50% or greater) or asymptomatic extracranial carotid artery stenosis (stenosis of 70% or greater) meeting the indications for interventional treatment (stenosis degree measured by the NASCET method); 3. Pre-treatment modified Rankin Scale (mRS) score of 0 to 1; 4. Planned for stent treatment by the clinical care team; 5. Informed consent obtained from the patient or their legally authorized representative. Exclusion Criteria： 1. Occlusion or severe stenosis (70% or greater) of the intracranial segment of the ipsilateral internal carotid artery system; 2. Occlusion or severe stenosis (70% or greater) of the contralateral common carotid artery or internal carotid artery; 3. History of stenting in the head and neck vessels within 3 months; 4. Coexisting other cerebrovascular diseases, such as intracranial aneurysms greater than 5 mm or cerebrovascular malformations; 5. Onset of stroke within 7 days; 6. Large old infarctions from previous stroke that may confound the evaluation of endpoints; 7. Contraindications to magnetic resonance imaging (MRI); 8. Definite risk of cardiogenic embolism (e.g., atrial fibrillation, atrial flutter, intracardiac thrombus) or clear indications for anticoagulation therapy; 9. Absolute or relative contraindications to antiplatelet therapy; 10. Pregnant or lactating women; 11. Allergy or hypersensitivity to contrast media or stent materials (e.g., Nitinol); 12. Life expectancy less than 1 year; 13. Pre-existing neurological or psychiatric disorders (e.g., severe dementia) that would confound neurological assessments; 14. Severe renal insufficiency (eGFR less than 30 mL/min).
