The U.S. Food and Drug Administration announced approval of the Maestro Rechargeable System for certain obese adults. According to an FDA press release, Maestro is the first weight loss treatment device that targets the nerve pathway between the brain and the stomach that controls feelings of hunger and fullness.
Maestro Rechargeable System is approved to treat patients aged 18 and older who have not been able to lose weight with a weight loss program, and who have a body mass index of 35 to 45 with at least one other obesity-related condition, such as type 2 diabetes.
“Obesity and its related medical conditions are major public health problems,” said William Maisel, M.D., M.P.H., deputy director for science and chief scientist in the FDA’s Center for Devices and Radiological Health. “Medical devices can help physicians and patients to develop comprehensive obesity treatment plans.”
The Maestro Rechargeable System consists of a rechargeable electrical pulse generator, wire leads and electrodes implanted surgically into the abdomen, FDA says. It works by sending intermittent electrical pulses to the trunks in the abdominal vagus nerve, which is involved in regulating stomach emptying and signaling to the brain that the stomach feels empty or full. Although it is known that the electric stimulation blocks nerve activity between the brain and the stomach, the specific mechanisms for weight loss due to use of the device are unknown.
External controllers allow the patient to charge the device and allow health care professionals to adjust the device’s settings in order to provide optimal therapy with minimal side effects.
