The invention describes a percutaneous gastrointestinal anchoring kit having an anchor, an introducer, a guide, an inflator, and a retainer. The anchor contains a ballooned region and a shaft portion. The retainer secures the anchor within the stomach when the ballooned region is inflated by seating against an exterior surface of the patient body and placing a tractive force on the ballooned region so as to pull the gastric lumen to an interior abdominal wall of the patient body. The introducer is used to insert the anchor initially within the stomach. The guide positions the ballooned region of the anchor within the stomach by enabling manipulation from an exterior surface of the patient body. The inflator is used to selectively inflate or deflate the ballooned region as needed.
