Further study details as provided by Cierra:

Primary Outcome Measures:
  • PFO closure 6 months post procedure [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • PFO closure at 30 days and 12 months post procedure [ Time Frame: 30 days, 12 months ]
  • AE event rates for all subjects [ Time Frame: 30 days, 6 and 12 months ]
  • Migraine severity [ Time Frame: 6 and 12 months ]

Estimated Enrollment: 100
Study Start Date: May 2006
Estimated Study Completion Date: December 2007
Detailed Description:
Patent Foramen Ovale has been implicated in the etiology of paradoxical embolism, cryptogenic stroke, transient ischemic attack, and right to left gas embolism in severe decompression illness. An association between patent foramen ovale and severe migraine headaches has also been reported. Several implantable devices are being used for percutaneous closure of patent foramen ovale; this study uses a non-implantable system to safely effect closure with the application of radiofrequency energy.
