Aneurysm, Brain
Conditions
Brief summary
The objective of this study is to demonstrate the safety and efficacy of the Penumbra SMART COIL® System, including the WAVE™ Extra Soft Coils (WAVE) as a fill and finish coil, in the treatment of intracranial aneurysms. Imaging will be analyzed by an independent core lab to assess aneurysm occlusion rates and perform a comparative analysis between imaging modalities.
