About BarioSurg

BarioSurg, Inc., formerly known as Onciomed, Inc., is a privately held medical device company that has developed a proprietary long term, minimally invasive and reversible device, the Gastric Vest System™ (GVS) to treat obesity and glycemic control and dominate the multi-billion dollar obesity and diabetes market with this revolutionary and disruptive bariatric technology.

The GVS was designed to address the largest healthcare problem by meeting the needs of our valued patients.
