Intracranial Aneurysm | Device: FRED and FRED Jr |
This is a multi-center observational study. Treatment and follow-up visits will be performed as per standard of care. The purpose of this study is to demonstrate that use of the FREDTM/FREDTM Jr Embolic device in intracranial aneurysm treatment is safe and effective when assessed at 6, 12 months and yearly up to 5 years post procedure.
150 patients will be enrolled over an 15-month recruitment period. All patients will be followed for 5 years.

Accepts Healthy Volunteers: | No |
Sampling Method: | Non-Probability Sample |
Inclusion Criteria:
- Patient older than 18 years old
-
Patient harboring a non-acutely ruptured intracranial aneurysm within the last 30 days of presentation:
- for which use of FRED or FRED Jr has been deemed appropriate
- being the only aneurysm to require treatment within the next 12 months
- and optionally previously treated by surgery (clipping) or with an intrasaccular device: aneurysm recanalized

- The aneurysm to be treated is associated with a cAVM
- The aneurysm to be treated is in the posterior circulation
- The aneurysm to be treated has a stenosis of its parent artery >50%
-
Patient has another aneurysm previously treated with a stent or a flow diverter
- on the same parent vessel at any time
- on a different parent vessel, less than 3 months prior to the procedure (previously-implanted stents in the non-index proximal carotid are acceptable)
- Patient with whom anticoagulant, antiplatelet or thrombolytic drugs are contra-indicated or test performed regarding AP medication administered is not efficient for the patient
- Patient with known hypersensitivity to contrast products or nickel titanium, not treatable
- Pregnancy or child breastfeeding
- Patient unable or unlikely to complete required follow up
- Patient has severe or fatal comorbidity or a life expectancy of less than 1 year
- Treatment with a flow diverter other than FRED/FRED Jr or in addition to FRED/FRED Jr is planned
