FDA Approves Implantable Electrical Anti-Hunger Device For Obese Patients

February 11, 2015: 12:00 AM EST
The FDA has approved the use of an electrical device to treat obese patients – BMI higher than 35 -- age 18 and older who have not been able to diet away their excess pounds. The Enteromedics Maestro Rechargeable System targets the nerve pathway between the brain and stomach that controls feelings of hunger and fullness. A rechargeable electrical pulse generator, wire leads and electrodes implanted surgically into the abdomen send intermittent electrical pulses to the abdominal vagus nerve. A clinical study testing safety and effectiveness found that after 12 months, the experimental group (with an activated implanted Maestro) lost 8.5 percent more excess weight than the control group (whose Maestro was implanted but not activated).
