If you are a candidate for weight loss surgery, you are most likely considering all of your options concerning which procedure is right for you. Each bariatric procedure is performed in its unique manner, resulting in different outcomes. At Nix, we have experienced surgeons and staff ready to assist you in determining which bariatric procedure is best for you.

What is the VBloc Procedure?

The vBloc procedure involves placement of a neurostimulator leads around the vagus nerves which link the brain and stomach to provide feedback about hunger. Patients generally feel full on smaller portions of food for a longer period of time. This surgery is performed as an outpatient procedure with minimally invasive techniques. The device can be deactivated or removed at any time.

The vBloc varies from other treatments and operations available to you as it is not designed to prevent your body from absorbing nutrients and altering your stomach during surgery. VBloc is available for patients who not interested in Gastric Bypass and other bariatric and metabolic surgeries. The procedure is designed for patients who wish to target the source of your hunger. The vBloc is FDA approved and available for patients that are approved for the procedure and meet the requirements.

The vBloc procedure uses a pacemaker-like implant to intermittently block the vagus nerve signals that control your food intake and processing. The device is implanted underneath the skin. The device consists of an implantable neuroregulator and two electrodes, which are placed at the trunk of the vagus nerve just above where the esophagus and stomach meet. The vBloc intermittently blocks signals preventing the vagus nerve from blocking them in order to control food consumption. Once the device is inserted, your surgeon will program it to provide the frequency and timing of signal blocking that is unique to you.
