Brief Summary:
A prospective, multicenter, observational evaluation of the safety and efficacy of the FRED® device in the treatment of intracranial aneurysms

Condition or disease Intervention/treatment
Intracranial Aneurysm Device: FRED and FRED Jr

Detailed Description:

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.

Intervention Details:
  • Device: FRED and FRED Jr
    Subjects aged ≥ 18 requiring treatment for an unruptured or recanalized intracranial aneurysm
    Other Name: Flow Re-Direction Endoluminal Device

Primary Outcome Measures :
  1. Rate of complete aneurysm occlusion without associated stenosis of the parent artery (> 50%) [ Time Frame: 12 months ]

    Complete occlusion (Raymond Scale grade I) without stenosis of the parent artery.

    Raymond scale definition: Grade I= complete occlusion of aneurysm, Grade II= Residual neck, Grade III= Residual aneurysm

  2. Morbidity Rate [ Time Frame: 6 months ]
    Patients with mRS>2

  3. Mortality Rate [ Time Frame: 6 months ]
    Deaths within 6 months after treatment

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients who are at least 18 years of age presenting with an unruptured or recanalized intracranial aneurysm requiring endovascular treatment. Those eligible to be treated with FRED/FRED Jr will be enrolled after having signed an informed consent form.

Inclusion Criteria:

  1. Patient older than 18 years old
  2. 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
  3. Patient with a modified Rankin Scale (mRS) ≤ 2
  4. Patient has received information about data collection and has signed and dated an Informed Consent Form

Exclusion Criteria:

  1. Patient has suffered from an ICH within the 30 days prior to the procedure.
  2. The aneurysm to be treated is associated with a cAVM
  3. The aneurysm to be treated is in the posterior circulation
  4. The aneurysm to be treated has a stenosis of its parent artery >50%
  5. 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)
  6. Patient with whom anticoagulant, antiplatelet or thrombolytic drugs are contra-indicated or test performed regarding AP medication administered is not efficient for the patient
  7. Patient with known hypersensitivity to contrast products or nickel titanium, not treatable
  8. Pregnancy or child breastfeeding
  9. Patient unable or unlikely to complete required follow up
  10. Patient has severe or fatal comorbidity or a life expectancy of less than 1 year
  11. Treatment with a flow diverter other than FRED/FRED Jr or in addition to FRED/FRED Jr is planned
