Outcome Measures

Primary Outcomes (3)

  • Successful Wingspan™ Stent Implantation (Access to the Lesion With the Stent, Accurate Deployment of the Stent Across the Target Lesion)

    The number of Wingspan Stents successfully deployed across the target lesion.

    Peri-procedural

  • Cumulative Morbidity and Mortality Rate (Ischemic Event, Parenchymal Brain Hemorrhage, Subarachnoid or Intraventricular Hemorrhage or Death)

    Any stroke or neurological death at \</= 30 days will be included in the cumulative morbidity and mortality rate. There was a 14.6% rate of cumulative morbidity and mortality at 30 days comprised of 12 events/82 patients.

    30 days

  • Rate of Recurrent Ischemic Stroke in the Target Territory

    The rate of recurrent ischemic stroke from 31 days to 12 months post procedure was 1.3% or 1 event per 77 patients analyzed.

    12 Months

Secondary Outcomes (2)

  • Cumulative Stroke Rate at 12 Months

    12 months

  • Rate of Restenosis

    12 Months

Interventions

The Wingspan Stent System is used in conjunction with Gateway PTA Balloon Catheter to improve cerebral artery lumen diameter in patients with intracranial atherosclerotic disease. The Gateway Balloon Catheter is indicated for balloon dilation of the stenotic portion of intracranial arteries prior to stenting the artery for the purpose of improving intracranial perfusion.

Also known as: Wingspan™ Stent System, 3.5F Delivery Catheter (pre-loaded with Wingspan™ Stent), Gateway™ Over-The-Wire PTA Balloon Catheter, Rotating Hemostatic Valve

Eligibility Criteria

Age41 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with symptomatic intracranial atherosclerotic stenosis. Patients will be included who are eligible for endovascular treatment and for which treatment with the Wingspan™ Stent system has been judged necessary by the treating physician.

You may qualify if:

  • Symptomatic stenosis of one of those intracranial arteries: Internal carotid artery (ICA ), M1 segment of the MCA, V4 segment of vertebral artery, basilar artery
  • A Modified Rankin Score of ≤ 3
  • A target vessel diameter between 2mm and ≤ 4.5mm
  • Length of the target lesion of ≤ 14 mm
  • Patient older than 40 years old

You may not qualify if:

  • 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)
