  Patient Pre-qualification Survey    
 
The PRIMA Trial is a clinical study designed to evaluate the effectiveness of PFO closure for migraine. PFO closure is performed by placing an occlusion device into the PFO through a catheter in a catheterization laboratory setting.

Normal Blood Flow
Normal blood flow through the
    heart
  PFO Blood Flow
A PFO can allow blood from the
    right side of the heart to pass
    through, or "shunt" to the left
    side of the heart

The trial will measure and compare headache frequency and severity from those who receive PFO closure to those who do not. Approximately 144 patients will be randomized in the PRIMA Trial at approximately 15 sites in the EU and Canada.
