Abstract:
1. An untethered, high specific gravity, antrum-based, intragastric device, comprising: a single expandable casing having a biocompatible outer surface and, upon expansion, a predetermined shape for contacting the antrum of the stomach of a subject; wherein, the expanded casing has and, a high specific gravity material, wherein the high specific gravity material has a specific gravity that is greater than 1.2 and contributes to an in vivo specific gravity of the device that ranges from about 1.2 to about 2.1, wherein the specific gravity functions to direct the device to the pyloric antrum of the subject to induce gastric discomfort during use of the device; wherein, the specific gravity of the device allows the device to move freely about the distal stomach and apply pressure to the antrum without otherwise affecting normal gastric function of the subject.
