One of the objectives of weight loss surgery is to reduce the amount of food that the stomach or intestine can accept. A surgery can either decrease the size of the stomach, reroute by joining part of the stomach and the small intestine or use a surgical implant to narrow the entrance to the stomach. All these technique and many more have been used successfully with the objective of creating restriction that results in the sensation of fullness and early satiety. 

The problem arises when the need to objectively measure that restriction is required. Then only subjective calculations can be made, usually with images from x-ray of simple cat scans.

Dr Ortiz designed a simple experiment where he used a simple combination of gas, pressure, a distal inflation balloon and flowmeter and barometer. With this combination of devices and the miniaturization and bluetooth technology he devised a way to measure the volume of a gastric pouch at a given inflation pressure and could then correlate this measurement to metrics of a same surgery group to understand the impact size has on satiety, weight-loss and many other factors. 

Callibra, has been awarded a provisional patent and additional clinical applications are being researched for the device.
