Abstract:
1. A passive intragastric obesity treatment implant, comprising: an inflatable body having a length sufficient to extend between the esophageal sphincter at a superior end of the body and the pyloric sphincter at an inferior end of the body upon implant in the stomach, and a width sufficient to contact the interior stomach walls upon contraction thereof, the body being rounded and slightly tapered so as to generally conform to the volume of an adult stomach cavity, the body including a series of chambers fluidly connected so as to be capable of simultaneous inflation and deflation, wherein two chambers at the superior end are separated from each other by an annular recess that is positioned to open to the esophageal sphincter, and wherein apertures in the annular recess open to a central flow channel that extends from the annular recess to the inferior end of the body, wherein the central flow channel extends through at least two chambers between the annular recess and the inferior end of the body, the implant being formed of a material which permits it to be compressed into a substantially linear delivery configuration and that will resist degradation over a period of at least six months within the stomach.
