NCT04518670

Brief Summary

The Comaneci Embolization Assist Device is indicated for use in the neurovasculature as a temporary endovascular device used to assist in the coil embolization of wide-necked intracranial aneurysms with a neck width ≤ 10 mm. A wide-necked intracranial aneurysm (IA) defines the neck width as ≥ 4 mm or a dome-to-neck ratio \< 2. The objective of the Postmarket Surveillance Plan is to assess safety and performance as used in postmarket clinical practice in the U.S.

Outcome Measures

Primary Outcomes (6)

  • Periprocedural Events

    Rates of all adverse events occurring within 24 hours post-procedure and hospital discharge status.

    24 Hours post procedure

  • Adverse Events

    All adverse events at discharge and up to 30 days post procedure.

    30 days post procedure

  • Functional Status

    Functional status at discharge and 30 days assessed using the modified Rankin Scale (mRS). using the modified Rankin Scale (mRS). This scale runs from 0-6, from no symptoms to death as follows: * 0 - No symptoms * 1 - No significant disability. Able to carry out all usual activities, despite some symptoms. * 2 - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities. * 3 - Moderate disability. Requires some help, but able to walk unassisted. * 4 - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted. * 5 - Severe disability. Requires constant nursing care and attention, bedridden, incontinent. * 6 - Dead.

    30 days post procedure

  • Number of Participants With Successful Intracranial Aneurysm Occlusion

    Successful intracranial aneurysm occlusion (measured by Raymond Roy classification I or II) at the end of procedure, using digital subtraction angiography (DSA).

    end of procedure

  • Number of Participants With Successful Intracranial Aneurysm (IA) Occlusion

    Successful intracranial aneurysm (IA) occlusion, that is a stable IA occlusion, measured by Raymond Roy classification I or II taken at 6 months (± 21d) post procedure without the need for re-treatment of the target IA, using DSA.

    6 Months Post procedure

  • Number of Participants With Good Clinical Outcome

    Good clinical outcome- mRS shift @ 6 months (change @ 6 months from pre procedure) and tetrachotomized (0,1, 2, 3-6) mRS analysis

    6 Months Post procedure

Interventions

assist in the coil embolization of wide-necked intracranial aneurysms with a neck width ≤ 10 mm.

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The Postmarket Sureveillance Study will include male or female patients with wide-necked ruptured and/or unruptured intracranial aneurysms that may require adjunctive assistance with coil embolization during the surgical procedure.

You may qualify if:

  • Patient has a documented intracranial ruptured or unruptured aneurysm, suitable for embolization by coils.
  • Patient is considered for treatment with coil embolization assisted by the Comaneci Device for wide-necked intracranial aneurysms with neck width ≤ 10 mm. A wide-necked intracranial aneurysm is defined by the neck width as ≥ 4 mm or a dome-to-neck ratio \< 2.
  • A signed informed consent by the patient or legally authorized representative

You may not qualify if:

  • \. Patient with known hypersensitivity to nickel-titanium
