Eligibility Criteria

Inclusion Criteria

- Presence of cryptogenic ischemic stroke or TIA of presumed embolic infarction verified by a neurologist within 180 days prior to randomization
- Presence of Patent Foramen Ovale (PFO), as determined initially by positive bubble study utilizing transesophageal echocardiography (TEE), demonstrating spontaneous right-to-left shunting or right-to-left shunting during Valsalva maneuver.
- Absence of an identifiable source of thromboembolism in the systemic circulation
- No evidence of a hypercoagulable state
