Abstract:
1. A passive intragastric obesity treatment implant, comprising: an esophageal mounting stent sized to anchor within the esophagus just above the esophageal sphincter, the stent having an accordion-like spiral structure including a plurality of triangular membranes that are each bordered on two sides by an upper strut and a lower strut, with an outer edge being free, the stent having a configuration that allows it to change its outer diameter while maintaining an inner diameter aperture substantially constant in a size suitable to allow passage of a food bolus; and an enlarged cardia-stimulating umbrella tethered to the esophageal stent having a contracted columnar shape for delivery and an expanded splayed out shape that abuts against the cardia surrounding the esophageal sphincter, the implant being formed of materials that permit it to be compressed into a substantially linear transoral delivery configuration and that will resist degradation over a period of at least six months within the stomach.
