The study evaluates the safety and efficacy of the vBloc Therapy delivered by the Maestro Rechargeable System for the treatment obesity. The Maestro Rechargeable System delivers intermittent, electrical blocking signals to the anterior and posterior trunks of the intra-abdominal vagus nerve (termed vBloc Therapy) and is designed to reduce sensations of hunger and produce satiety leading to weight loss. After approval from the institutional review board, subjects will provide written consent and will receive a device implanted using laparoscopic placement of the leads and neuroregulator. Recommendations regarding diet, exercise, and behavior modification will be provided throughout the study. Weight, adverse events and other supportive measures are evaluated throughout the 60 month study duration.
