4. Diagnosis of patent foramen ovale (PFO) meeting the criteria established by the American Society of Echocardiography (ASE) and the Society for Cardiovascular Angiography and Interventions (SCAI) (2015 edition), with right-to-left shunting (RLS) of grade II or higher upon Valsalva maneuver, as assessed by contrast-enhanced echocardiography;
5. Stable antiseizure medication regimen for at least four weeks prior to screening, with willingness to maintain a stable regimen throughout the study period;
6. At least one documented seizure episode during a six-week screening period (with a minimum of four weeks of effective seizure diary recordings) and a retrospective self-reported history of at least 12 seizures in the year preceding screening;
7. Ability to independently or with caregiver assistance complete a seizure diary and comply with clinical data collection and required medical examinations;
8. Willingness to undergo the investigational treatment and voluntary provision of written informed consent.
Exclusion Criteria:
1. Patients diagnosed with epilepsy of a known etiology, including infectious, metabolic, immune, genetic, or structural causes;
2. History of stroke or psychogenic nonepileptic seizures (PNES);
3. History of epilepsy surgery or implantable neurostimulation therapy, or planned epilepsy surgery, neurostimulation therapy, ketogenic diet therapy, or other antiseizure interventions during the study period;
4. Presence of structural cardiac abnormalities other than patent foramen ovale (PFO), such as moderate or severe valvular regurgitation or pulmonary hypertension;
5. Presence of severe central nervous system (CNS) diseases, including acute cerebrovascular disease, intracranial tumors, intracranial infections, or progressive CNS disorders;
6. Evidence of vascular puncture site infection or difficulty with puncture as assessed by transesophageal echocardiography combined with contrast-enhanced right heart echocardiography;
7. Documented contraindications to antiplatelet therapy;
8. Presence of severe psychiatric disorders, such as schizophrenia, bipolar disorder, or severe depression or anxiety;
9. History of alcohol or other substance abuse;
10. Severe dysfunction of vital organs (heart, lungs, liver, kidneys) deemed by the investigator to pose a risk to the participant or impair the participant's ability to complete the study;
11. Pregnant or breastfeeding women, or women planning to conceive during the study period;
12. Participation in another interventional clinical trial within three months prior to signing the informed consent form, current participation in another interventional trial, or plans to participate in another interventional trial during the study period; inability to comply with follow-up due to travel or relocation;
