Primary Outcome Measures

eCLIPs Bifurcation Remodelling System Technical Success
The proportion of successful eCLIPs device implants at the target aneurysm.
No participant incurs a major stroke or death within 30 days or major territorial stroke or neurological death within 6 months.
A major stroke is defined as a new neurological event that persists for >24 hours and results in a 4 point increase in the NIHSS score compared to baseline or compared to any subsequent lower score.

5. Study Description

Brief Summary
The purpose of this study is to evaluate the safety and feasibility of the eCLIPs™ Family of Products for the treatment of unruptured intracranial bifurcation aneurysms in conjunction with embolization coils.
Detailed Description
With this other endoluminal stent/device implantation technique to treat intracranial aneurysms in conjunction with embolic coils, the neurovascular device is placed across the aneurysm neck, to act as a bridge to prevent coils from protruding into the parent artery. Stenting may allow to more safely achieve a higher packing density of coils. These effects may improve the rates of complete aneurysm occlusion and enhance the durability of the coiling treatment. The eCLIPs™ device manufactured by Evasc Medical Systems Corp. has a high density 'leaf' which is implanted across the bifurcation aneurysm neck and anchored in one of the branch arteries of the bifurcation and may provide improved bifurcation aneurysm treatment by allowing for a higher packing density of embolic coils implanted behind the eCLIPs™ device and the eCLIPs™ device in combination with embolic coils may reduce the recurrence/retreatment rate by increasing the rate of complete aneurysm occlusion.

Primary Outcome Measure Information:
Title
eCLIPs Bifurcation Remodelling System Technical Success
Description
The proportion of successful eCLIPs device implants at the target aneurysm.
Time Frame
24 hours
Title
No participant incurs a major stroke or death within 30 days or major territorial stroke or neurological death within 6 months.
Description
A major stroke is defined as a new neurological event that persists for >24 hours and results in a 4 point increase in the NIHSS score compared to baseline or compared to any subsequent lower score.
Time Frame
30 day-6 month
Other Pre-specified Outcome Measures:
Title
eCLIPs Microcatheter Technical Success
Description
The proportion of procedures where the eCLIPs Microcatheter is able to access the target vasculature and successfully deliver the eCLIPs device.
Time Frame
24 hours
Title
eCLIPs Micro-Introducer Technical Success
Description
The proportion of procedures where the eCLIPs Micro-Introducer successfully is used conjunction with the eCLIPs Microcatheter to assist in the delivery of the eCLIPs Microcatheter to the target aneurysm.
Time Frame

Title
eCLIPs Detacher Technical Success
Description
The proportion of procedures where the eCLIPs Detacher is successfully used in conjunction with the eCLIPs Bifurcation Remodelling System to initiate detachment of the eCLIPs Device.

Title
Measurement of aneurysm occlusion at 6 months
Description
Successful aneurysm treatment with the eCLIPs™ device and embolic coils, as measured by aneurysm occlusion of ≥ 70% (Meyers grade of 2 or less) at 6 month follow up as measured by using standard medical practice radiographic imaging of either angiography, magnetic resonance angiography (MRA), or computed tomography angiography (CTA). The type of follow-up imaging is determined at the discretion of the treating physician.
Time Frame
6 months
Title
Occurrence of unplanned aneurysm re-treatment within 6 months (endovascular or surgical repair).
Description
As determined by the treating physician, where the patient has a ≤70% aneurysm occlusion corresponding to a Meyer's aneurysm occlusion grade of greater than 2 and the treating physician judges the need for the re-treatment.
Time Frame

Title
Assessment of Device Migration at 6 months.
Description
Radiographic images will be comparing post procedure device position to 6 months position to determine if migration has occurred. Imaging from each participant will be reviewed by an independent neuroradiologist who will be comparing baseline.
Time Frame
6 months
Title
Assessment of artery stenosis at the device location at 6 months
Description
Branch arteries will be measured at baseline and compared radiographically at 6 months post procedure per review by the Independent neuroradiologist.

Title
Determination of percentage of screened patients who are eligible for the study
Description
The number of screened patients represents those patients reviewed by the investigator who have a known aneurysm and are considered for inclusion in the study.
