Bari Calibration Tube

Single Use Sterile Bari Calibration Tube

The tube is used for gastric pouch sizing during Sleeve Gastrectomy & Mini Gastric Bypass/One-Anastomosis Gastric Bypass, or revision surgery for these procedures.

The tube is made of medical grade silicone, which does not become weak and floppy after being exposed to body temperature, unlike regular PVC tubes. Floppy tubes are difficult to guide into a certain direction and tend to kink easily.

The tube has a soft tip, mixed with barium sulphate, making it visible on X-ray. The tip has a suction hole in it as well, to avoid creation of a vacuum between the tube and the stomach wall, hence with avoiding damage to the stomach while pulling the tube out after the leak test.

6 small holes are provided for suction and aspiration, avoiding kinking of the tube because of holes being too large. Large holes also have a tendency to have stomach tissue sucked into the hole when aspirated, leading to internal bleedings of the stomach and vacuum formation.

Proximally, There is a special Universal Connector which allows for easy placement of various types of syringes for administration of fluid for leak testing, and for aspiration of stomach contents or removal of residual fluid after leak testing.

Fingertip control of suction is provided as well as a clip at the proximal end to close the tube and prevent backflow of fluid during leak testing.
