Outcome Measures

Primary Outcomes (2)

  • Primary Effectiveness Endpoint

    The primary effectiveness endpoint of this study is a composite of 100% occlusion (Raymond 1, complete occlusion) of the target aneurysm without significant parent artery stenosis (\>50% stenosis), per independent core lab assessment of digital subtraction angiography (DSA) images acquired at 12 months (± 3 months) post-procedure, and with no target aneurysm retreatment.

    12 months (± 3 months) post procedure

  • Primary Safety Endpoint

    The primary safety endpoint of this study is neurologic death, or disabling stroke at 12 months as adjudicated by an independent Clinical Events Committee (CEC).

    12 Months (± 3 months) post procedure

    3 Year Follow-Up

Study Arms (1)

Surpass Evolve Flow Diverter System

EXPERIMENTAL

This is a prospective single arm study in which all subjects who present for flow diverter implantation, provide informed consent, and meet inclusion/exclusion criteria may receive treatment (Surpass Evolve Flow Diverter).

Device: Surpass Evolve Flow Diverter System

Interventions

The Surpass Evolve Flow Diverter System is indicated for the endovascular treatment of adults (age 18 or above) with unruptured saccular wide-neck or fusiform intracranial aneurysms ≤12 mm.

Eligibility Criteria

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

You may qualify if:

  • Age is ≥ 18 and ≤ 80 years
  • Has a single unruptured target intracranial aneurysm (IA) with the following characteristics:
  • Is located on the internal carotid artery (ICA) or its branches.
  • Has a neck ≥ 4 mm, dome to neck ratio ≤ 2.0, or no discernible neck
  • Aneurysm size is ≤ 12 mm (saccular or fusiform configuration)
  • Has a parent vessel diameter ≥ 1.75 mm and ≤ 5.0 mm at both the proximal and distal segments where the implant will be placed
  • Has multiple increased risk factors for intracranial (IA) aneurysm rupture, including but not limited to, aneurysm morphology, smoking, hypertension, diabetes, age, prior and/or family history of rupture, and/or history of subarachnoid hemorrhage that may result in a benefit risk profile of endovascular treatment that outweighs the risks of intracranial aneurysm rupture during the subject's expected lifetime if left untreated.

You may not qualify if:

  • Has an extradural target aneurysm
  • Has a target aneurysm in the posterior circulation
  • Perforator or branch vessel, inclusive of the posterior communicating artery, arises from the target aneurysm body or neck (branches or arteries must arise or connect from the parent vessel separate from the aneurysm or neck to not be excluded from study)
  • Has a true bifurcation aneurysm, defined as an aneurysm (saccular or non-saccular) located at a point of vessel bifurcation
  • Target aneurysm is unsuitable for flow diverter treatment
  • Has vessel characteristics, such as severe tortuosity (cICA Type IV), stenosis (\>70%), or morphology that would preclude safe endovascular access to the target aneurysm necessary for treatment with the study device
  • Received previous treatment of the target aneurysm or parent artery where it would interfere with the placement or proper apposition of the device
  • Has a medical contraindication to study or procedure related antiplatelet medications (aspirin, clopidogrel/Plavix, ticagrelor, and heparin), local or general anesthesia, or life-threatening allergy to contrast dye
  • Has a known severe allergy to nickel, chromium cobalt, tungsten or platinum.
  • Modified Rankin Score (mRS) assessment is ≥ 3 at preprocedure exam
  • Presence of unstable neurological deficit (i.e., worsening of clinical condition in the last 30 days)
  • Subarachnoid hemorrhage occurred within 30 days prior to enrollment
  • Major surgery (including previous intracranial implant) occurred within previous 30 days or is planned in the next 120 days after enrollment date
  • Has more than one IA that requires treatment within 12 months
  • Received previous intracranial implant associated with the symptomatic or vascular distribution within the past 12 weeks prior to treatment date
  • +9 more criteria
