Outcome Measures

Primary Outcomes (5)

  • Number of patients with Modified Raymond Roy 1-2 Occlusion classification without retreatment

    Modified Raymond Roy 1-2 occlusion at 18 months without retreatment. The Raymond-Roy Occlusion Classification has 3 responses, where Grade 1 is complete occlusion, no flow of contrast seen in the sac, Grade 2 is partial occlusion, some flow in the neck or sac, and Grade 3 is incomplete occlusion, apparent flow into the sac. Grade 1 indicates the best outcome.

    at 18 months

  • Number of coils used

    Number of coils used to assess treatment-related cost effectiveness at treatment and over the course of follow-up to 18 months.

    up to 18 months post-treatment

  • Packing density of coils

    Packing density of coils used to assess treatment-related cost effectiveness at treatment and over the course of follow-up to 18 months.

    up to 18 months post-treatment

  • Number of device related serious adverse events

    Intra and peri-procedural (0-24 hours) device related serious adverse event rate.

    up to 24 hours

  • Number of device related serious adverse events

    Intra and peri-procedural (24 hours to 30 days) device related serious adverse event rate.

    24 hours to 30 days

Secondary Outcomes (12)

  • Rate of complete or near complete aneurysm occlusion without retreatment

    at 6 months

  • Number of patients with Modified Raymond-Roy classification 1

    at 18 months

  • Number of patients who suffer a Major ipsilateral stroke or neurological death

    at 6 months

  • Number of patients who suffer a Major ipsilateral stroke or neurological death

    at 18 months

  • Changes in Modified Rankin Scale (mRS) score

    Day 30, 6 months, and 12-18 months

  • +7 more secondary outcomes

Study Arms (2)

Kaneka i-ED coil

EXPERIMENTAL

Patients in the experimental arm will be treated according to the standard of care for endovascular aneurysm coiling, with no procedural modifications related to the use of the experimental device.

Device: Kaneka i-ED coil

Matched patients who underwent intracranial aneurysm embolization

NO INTERVENTION

The comparator arm will be comprised of propensity matched patients who underwent intracranial aneurysm embolization as part of the FEAT Trial (NCT01655784).

Interventions

The study device is the Kaneka i-ED coil T, FDA cleared under 510K number K192068. The coil is indicated for use in the endovascular embolization of intracranial aneurysms and other neurovascular abnormalities such as arteriovenous malformations and arteriovenous fistulae.

Kaneka i-ED coil

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient presenting with ruptured or unruptured cerebral aneurysm appropriate for endovascular treatment as determined by the neuroendovascular treating team
  • Wide neck side wall or bifurcation intracranial aneurysms (neck \> or = to 4 mm or dome-to-neck ratio \< 2) within the anterior or posterior circulation
  • The neurointerventionist feels that the aneurysm can be safely treated using endovascular techniques (direct or assisted coiling)
  • Patients are 18-80 years of age (inclusive)
  • Patient must be Hunt and Hess grade 0 to 3
  • Patient has given fully informed consent to endovascular coiling procedure. If the patient cannot consent for themselves, appropriate written consent has been sought from their next of kin or appropriate power of attorney.
  • Aneurysm 6-14 mm in diameter
  • Patient is willing and able to return for clinical evaluation and follow-up imaging evaluation (angiography) at 3-6 months and 12-18 months after endovascular treatment
  • The patient has not been previously enrolled in this trial or another related ongoing trial
  • The aneurysm has not been previously treated by coiling or clipping

You may not qualify if:

  • Target aneurysm has had previous coil treatment or has been surgically clipped
  • Hunt and Hess score is 4 or 5 after subarachnoid hemorrhage
  • Inability to obtain informed consent
  • Medical or surgical comorbidity such that the patient's life expectancy is less than 2 years
