Arm Intervention/treatment
Experimental: Pipeline
Placement of Pipeline Embolization Device in the parent artery at the aneurysm location
Device: Pipeline Embolization Device (PED)
1 or more PEDs placed in the parent artery of the affected aneurysm via endovascular approach




Primary Outcome Measures :
  1. Number of Participants With the Occurrence of Major Ipsilateral Stroke or Neurologic Death and Occurrence of Ipsilateral Stroke or Neurologic Death. [ Time Frame: 180-days and 5-years ]
    The number of participants with occurrence of major ipsilateral stroke or neurologic death after PED placement at 180-days and the occurrence of ipsilateral stroke or neurologic death after Pipeline Embolization Devices (PED) placement at 5-years.

  2. Count of Intracranial Aneurysms (IA) Evaluated as Completely Occluded (100%) Without Major Parent Artery Stenosis. [ Time Frame: 180 days ]

    The count of Intracranial Aneurysms (IA) evaluated as completely occluded (defined as Raymond Grade 1) without major parent artery stenosis at 180 days. The Raymond-Roy Grade scale measures the amount of visual contrast flow throughout the aneurysm anatomy. The Raymond-Roy aneurysm occlusion scale is follows:

    Complete = complete occlusion, no flow of contrast seen in the sac Residual Neck = partial occlusion, some flow, or eddying flow, in the sac Residual Aneurysm = incomplete occlusion, apparent flow into the sac



Secondary Outcome Measures :
  1. Count of Intracranial Aneurysms (IA) Evaluated as Completely Occluded (100%) at 1 Year [ Time Frame: 1 Year ]

    The count of Intracranial Aneurysms (IA) Evaluated as Completely Occluded (100%) (defined as Raymond-Roy grade 1) 1 year follow-up visit. The Raymond-Roy Grade scale measures the amount of visual contrast flow throughout the aneurysm anatomy. The Raymond-Roy aneurysm occlusion scale is follows:

    Complete = complete occlusion, no flow of contrast seen in the sac Residual Neck = partial occlusion, some flow, or eddying flow, in the sac Residual Aneurysm = incomplete occlusion, apparent flow into the sac


  2. Count of Intracranial Aneurysms (IA) Evaluated as Completely Occluded (100%) at 3 Year Follow-up [ Time Frame: 3 years ]

    The count of Intracranial Aneurysms (IA) evaluated as completely occluded (100%) (defined as Raymond-Roy grade 1) at 3 year follow-up. The Raymond-Roy Grade scale measures the amount of visual contrast flow throughout the aneurysm anatomy. The Raymond-Roy aneurysm occlusion scale is follows:

    Complete = complete occlusion, no flow of contrast seen in the sac Residual Neck = partial occlusion, some flow, or eddying flow, in the sac Residual Aneurysm = incomplete occlusion, apparent flow into the sac


  3. Count of Intracranial Aneurysms (IA) Evaluated as Completely Occluded (100%) at 5 Years [ Time Frame: 5 years ]

    The count of Intracranial Aneurysms (IA) evaluated as completely occluded (100%) (defined as Raymond-Roy grade 1) at 5-year follow-up. The Raymond-Roy Grade scale measures the amount of visual contrast flow throughout the aneurysm anatomy. The Raymond-Roy aneurysm occlusion scale is follows:

    Complete = complete occlusion, no flow of contrast seen in the sac Residual Neck = partial occlusion, some flow, or eddying flow, in the sac Residual Aneurysm = incomplete occlusion, apparent flow into the sac


  4. Stenosis of the Parent Artery in PED at 3 Years [ Time Frame: 3-years ]
    Parent artery stenosis (narrowing of the artery from which the aneurysm arises) at 3-year follow-up

  5. Stenosis of the Parent Artery in PED at 5 Years [ Time Frame: 5-years ]
    Parent artery stenosis at 5-year follow-up

  6. Number of Participants With Device-Related Adverse Events at 3 Years [ Time Frame: 3 years ]
    Number of participants with incidence of device-related adverse events at 3 year follow-up

  7. Number of Participants With Device-related Adverse Events at 5 Years [ Time Frame: 5 years ]
    Subjects Observed with Device Related Adverse Events 5 years after Pipeline Placement
