A gastro-jejunal (G-J) feeding device (10) includes a gastro-jejunal body (12) and an integral feeding tube (16). The gastro-jejunal body (12) includes a gastric port (26), a jejunal port (28) and a balloon port (30). The integral feeding tube (16) includes a proximal end (16b) and a distal end (16c) and further includes a gastric lumen, a jejunal lumen and a balloon lumen. The proximal end (16b) is configured to be located outside of a patients body. The distal end (16c) 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 (18) is configured to be placed on the distal end (16c) so as to enclose and deform the deformable portion. The capsule (18) 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 (18).
