Abstract
An ingestible gastric device comprising a formed body that is adapted to expand upon exposure to a hydration medium and then degrade after a first residence time in the stomach cavity, allowing the device to be passed by the patient'"'"'s normal digestive process, and monitoring means for monitoring the gastric device. In some embodiments, the monitoring means comprises a biocompatible RFID tag.

5. A food grade ingestible gastric device, comprising:
-
a flexible pouch formed from a food grade biodegradable film, said pouch having a first volume that allows normal ingestion of said gastric device into a subject'"'"'s stomach, said pouch enclosing a sealed cavity having a core material disposed therein, said biodegradable film comprising a first gel-forming material selected from the group consisting of acacia (gum Arabic), agar, agarose, alginate gels, alginic acid, alginate gums, amylopectin, arabinogalactan, carob bean gum, carrageenan, chondroitin sulfate, eucheuma, fucoidan, furcellaran, gelatin, gellan, guar gum, gum ghatti, gum karaya, hypnea, laminaran, locust bean gum, natural gum, pectins, starches, polypeptides, polyamino acids, tragacanth, xanthan, psyllium, maltodextrin, and mixtures and combinations thereof, said core material comprising a hydratable material that is adapted to effectuate expansion of said sealed cavity upon hydration of said hydratable material by a gastric fluid, whereby upon a first hydration of said degradable film and, thereby, said hydratable material, by a first gastric fluid, said gastric device expands to a second volume greater than said first volume, said second volume being sufficient to preclude passage of said gastric device into said subject'"'"'s duodenum while still allowing food to pass therethrough, said gastric device being adapted to commence said first hydration after contact with said first gastric fluid for a period of time in the range of approximately 5-30 min, said gastric device being adapted to sufficiently degrade in said subject'"'"'s stomach after a first period of time to allow passage of said gastric device into said subject'"'"'s duodenum; said gastric device further including monitoring means for non-invasively monitoring the gastric device while disposed in a subject'"'"'s gastrointestinal tract. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method for monitoring a gastric device, comprising the steps of:
-
providing a gastric device having a formed body, said body being adapted to expand upon exposure to a hydration medium, and monitoring means for monitoring the gastric device; administering said gastric device to a subject; and externally interrogating said monitoring means to ascertain first data associated with the gastric device. - View Dependent Claims (18, 19, 20, 21, 22)
