An International Registry of the Wingspan™ Stent System for the Treatment of Intracranial Atherosclerotic Stenosis

An International Registry of the Wingspan™ Stent System for the Treatment of Intracranial Atherosclerotic Stenosis

The IRISS study is designed to collect clinical and angiographic outcomes data when stenting intracranial atherosclerotic lesions using the Wingspan™ Stent System with Gateway™ PTA Balloon Catheter in routine clinical practice.

The Wingspan™ Stent System and Gateway™ PTA Balloon Catheter have CE mark and are commonly used in Europe. All the data collected in this registry will be from patients treated according to the physician's choice, per instructions for use, per approved indications and per local standard of care. The results from this registry will provide an understanding of the use and outcomes associated with the Wingspan™ Stent in a real world setting.

• A target vessel diameter between 2mm and ≤ 4.5mm
• Length of the target lesion of ≤ 14 mm
• Patient older than 40 years old

Exclusion Criteria:

• Patient previously stented at the target lesion
• Intracranial stenosis related to disease such as: arterial dissection, Moya Moya disease, vasculitis, radiation induced vasculopathy or fibromuscular dysplasia
• Complete occlusion of the artery on the imaging assessment
• Contraindications to antithrombotic and/or anticoagulant therapies
• Women who are pregnant or breast-feeding
• Patient not likely to be available for follow-up
• Patient protected by the law (safeguard of justice, supervision or trusteeship)
