A gastric/jejunal catheter comprises three major components, a triple lumen “Y” connector, a transitional “midport” bolus, and a single lumen jejunal tube with a jejunal tip. The midport bolus, in turn, comprises three lumens, a jejunal feeding lumen, a gastric relief lumen and an air lumen. The midport bolus also contains inflow and outflow ports communicating with said lumens. The bolus contains a key reinforcing arc that prevents the kinking, and resultant jejuna lumen occlusion, of the bolus. |
