Arm Type
Experimental
Arm Label
Contour Neurovascular System placement
Arm Description
Treatment of intracranial aneurysm with the Contour Neurovascular System device.
Outcomes
Primary Outcome Measures
Percentage of Subjects With Major Ipsilateral Stroke/SAH or Death Due to Neurologic Cause Within Six (6) Months After Treatment.
Percentage of subjects with major ipsilateral stroke/SAH or death due to neurologic cause within six (6) months after treatment. All neurological events were adjudicated by an independent Medical Monitor.
Secondary Outcome Measures
Occlusion Status of the Target IA
Last known occlusion status of the target IA as judged by an independent core laboratory using the Raymond-Roy occlusion scale (Class 1 - Complete occlusion; Class 2 - Residual neck; Class 3 - Residual aneurysm).

Brief Summary
Prospective, single arm, multi centre study to evaluate the safety and performance of the Contour Neurovascular SystemTM in the treatment of intracranial aneurysm (IA)
Detailed Description
Prospective, single-arm, multi-centre European study to evaluate the safety and performance of the Contour Neurovascular SystemTM in the treatment of intracranial aneurysm (IA). Target aneurysms are unruptured aneurysms requiring endovascular treatment in the anterior and posterior cerebral circulation.
