A gastrostomy device includes an elongate tube extending from a proximal end to a distal end and having a tube diameter. The elongate tube has a length that enables the elongate tube to extend from a position exterior a patient to a position interior the patients stomach. A resealable valve is disposed within the proximal end of the elongate tube. An inflation lumen extends along the elongate tube and an inflation port is disposed near the proximal end of the elongate tube and is in fluid communication with the inflation lumen. A silicone balloon is secured relative to the distal end of the elongate tube and is in fluid communication with the inflation lumen. The silicone balloon has a distal region, a proximal region and an intervening middle region that, when inflated, stretches more than the distal region or the proximal region.
