Publication number: 20220125612Abstract: In one aspect, an obesity treatment device includes multiple inflatable space-filling compartments and a valve system for introducing fluid into each compartment, where the device forms, upon filing the compartments, to a curved shape conforming to a natural three-dimensional kidney shape of the stomach. In one aspect, a method for deploying a gastric balloon structure in a gastric cavity includes determining dimensions of the gastric cavity in a feeding state, selecting a fill volume for each of a number of isolated chambers of the balloon structure, and filling each chamber while the balloon structure is in the gastric cavity. In one aspect, a system for treating obesity includes a means for conforming a flexible, space-filling structure to a natural kidney shape of the gastric cavity, a means for maintaining at least two isolated inflatable regions of the flexible, space-filling structure, and a means for introducing fluid into each inflatable region.Type: ApplicationFiled: June 7, 2021Publication date: April 28, 2022Applicant: Fulfillium, Inc.Inventors: Richard D.Y.

Patent number: 9456915Abstract: Upon filling multiple inflatable chambers of a gastric balloon structure in a patient's stomach, the gastric balloon structure assumes a natural three-dimensional kidney shape of the gastric cavity. A flexible central spine may span a gap between two inflatable chambers and may include lumens for inflation of one or both chambers. The plurality of compartments, when in an inflated state, may form a cavity therebetween through which food may pass and may leave in a stomach a residual volume of 10 ml to 100 ml.Type: GrantFiled: December 16, 2015Date of Patent: October 4, 2016Assignee: FULFILIUM, INC.Inventors: Richard D.
