Detailed Description:

During the last five years, transcatheter and surgical closure of PFO in the cyrptogenic stroke and TIA population has grown in frequency world-wide. Observational retrospective reports, from both single and multi-center experiences of over 400 patients, suggest Patent Foramen Ovale (PFO) closure to reduce the risk of recurrent migraine events in these populations may be beneficial, particularly for those patients in the migraine with aura subgroup. Although none of these reports are from prospective, randomized, controlled trials, the reports are compelling enough in their totality to support further investigation of a well defined group in a prospective manner. The patients reported in these studies were brought to PFO closure with no expectation of their procedure having any impact on their migraine. In fact, in many cases, the discovery of a history of migraine was not made until well after the PFO closure procedure.

This clinical trial will prospectively compare the safety and effectiveness of PFO closure with the BioSTAR device to a control arm. Patients will be followed one year post-implant.
