WEB Clinical Assessment of IntraSaccular Aneurysm Therapy
The objective of this clinical study is to evaluate clinical utility of the WEB Aneurysm Embolization System used to embolize intracranial aneurysms

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
Observational Model: Cohort
