About this trial
The purpose of this study is to collect information about how the PHIL® Embolic System works in the treatment of intracranial dural arteriovenous fistulas. Data collected in this study will be used to evaluate the safety and probable benefits in treating DAVFs.
The PHIL® Embolic System is a Humanitarian Use Device (HUD). The U.S. Food and Drug Administration (FDA) approved the use of the PHIL Embolic System as a HUD in June 2016.
