Responsive Neurostimulation For Loss Of Control Eating

Korábbi kezelés

• Subject requires transcranial magnetic stimulation (TMS) or electroconvulsive therapy.
• Subject is likely to require repeat magnetic resonance imaging (MRI) after implant of the RNS Neurostimulator and Leads.
• Subject is participating in a therapeutic investigational drug or device study.
• Subject is actively using medication known to affect eating (e.g., appetite suppressants).
• Subject is a candidate for revision of their bariatric surgery due to anatomical or medical co-morbidities that could be addressed. Of note, revision of a sleeve gastrectomy to a gastric bypass for to reverse weight regain alone is less frequently considered a worthwhile effort as the average weight loss of such a revision is about a 10% weight loss. Thus, patients who have a sleeve and meet the Reinhold classification will be included in this study.
