At the proximal end, the tube is equipped with a check valve which mates with a syringe used to fill a balloon located approximately 6.8 cm from the distal tip. At the distal end, the tube has two suction/irrigation holes that allow the removal of fluids and/ or irrigation during the procedure, if necessary. Reference markings are provided on the tube shaft, with the zero reference located approximately 39.6 cm from the proximal end of the balloon. Indications for Use The gastric calibration tube is indicated for use in gastric and bariatric surgical procedures to provide visible and tactile delineation of the antrum of the stomach along with the ability to decompress the stomach, drain and remove gastric fluid and size a gastric pouch. Technological Characteristics The REALIZE™ Gastric Calibration Tube is similar to the design, function and materials of the predicate devices BioEnterics® Gastric Balloon Suction Catheter and COOK Gastric Sizing Balloon Catheter. The REALIZE™ Gastric Calibration Tube has the same indications for use as the predicates. Performance Data Bench testing was performed to evaluate the performance of the intended use of the new device. The performance testing shows that the REALIZE™ Gastric Calibration Tube is equivalent to the BioEnterics® Gastric Balloon Suction Catheter. {1}------------------------------------------------ ## DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/1/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
