An anchor and a valve are included on the base portion of the fillant delivery tube. A method of treating obesity including the steps of performing a percutaneous endoscopic gastrostomy to establish a gastro-cutaneous fistula, pushing an expandable body through said fistula into the gastric cavity with a rigid fillant delivery tube to which the expandable body is sealedly connected, the rigid fillant delivery tube including a base portion, an extending portion, a tip portion, and an anchor attached to the base portion, delivering a fillant through a valve connected to the fillant delivery tube such that the fillant flows into the fillant delivery tube and the expandable body to cause the expandable body to expand within the gastric cavity, delivering the fillant through the valve out of the fillant delivery tube and the expandable body to cause the expandable body to return to a non-expanded configuration, and removing the fillant delivery tube and the expandable body from the fistula.
