A gastro jejunal (G-J) feeding device includes a gastro jejunal body and an integral feeding tube. The gastro jejunal body includes a gastric port, a jejunal port and a balloon port. The integral feeding tube includes a proximal end and a distal end and further includes a gastric lumen, a jejunal lumen and a balloon lumen. The proximal end is configured to be located outside of a patients body. The distal end is configured to be inserted into a patients body and has a deformable portion with a default shape having a width larger than a diameter of a tubular portion. A capsule is configured to be placed on the distal end so as to enclose and deform the deformable portion. The capsule is configured to dissolve upon contact with bodily fluid. The deformable portion is configured to return to the default shape upon dissolution of the capsule.
