Index Embolization Cohort
WEB Aneurysm Embolization System
Procedure: Intracranial aneurysm embolization
Treatment of intracranial aneurysms

Detailed Description:

The following parameters will be evaluated as part of this study:

  • Aneurysm morphology
  • Aneurysm size
  • For ruptured aneurysms: Hunt and Hess Classification of Subarachnoid Hemorrhage (SAH)
  • Size of the embolization device(s) used in the procedure
  • Intra-procedural assessment of aneurysm occlusion and flow stasis
  • Degree of aneurysm occlusion post-procedure (percentage occlusion, Raymond Scale and other scores as appropriate)
  • Aneurysm occlusion durability
  • Recanalization rate
  • Device-related changes in Modified Rankin Scale from baseline
  • Complications/adverse events
  • Rebleed/new bleed

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

Subjects with:

- Diameter and width of the aneurysm is appropriate size for treatment with the WEB Aneurysm Embolization System per device Instructions for Use


Inclusion Criteria:

  • Must be at least 18 years of age
  • Must sign and date an IRB/EC-approved written informed consent prior to initiation of any study procedures

Exclusion Criteria:

  • Must not have clinical or angiographic evidence of vasospasm
  • Must not have lesion with characteristics unsuitable for endovascular treatment
  • Must not have neurologic or psychiatric conditions, which preclude ability to comply with all aspects of the screening, evaluation, treatment, and the post-procedure follow-up schedule
  • Must not be concurrently involved in another investigational or post-market study
  • Must not have received any investigational device for treatment of the target intracranial aneurysm prior to entry into this trial
