Benefits of technology

[0006]In another aspect, the present invention is directed to an obesity treatment device comprising filament filler material movable between a substantially straight insertion / removal configuration and an operative configuration in which the filament extends along one or more curves to occupy a selected volume within the stomach and a retrieval element connected to a proximal end of the filler material facilitating grasping and withdrawal of the filler material.

Problems solved by technology

Fluid filled and other non-floating filling devices apply a downward force to the stomach wall which also generates feelings of satiety.

first embodiment

[0014]An exemplary gastric filler according to the invention includes a gastric bubble formed with an integrated deflation and retrieval mechanism simplifying removal of the bubble after the desired treatment period has elapsed. The gastric bubble comprises a shell-like body formed of a polymeric wall including a failure zone pre-formed in the wall during a molding or other manufacturing operation as, for example, a weakening groove or indentation. The body may be a single filling volume or a series of filling volumes that are either independently or simultaneously fillable. As will be described in more detail below, during removal, the wall is torn along the weakening groove by the removal force, such that the balloon unwinds into an elongated strip that can be easily removed trans-orally. The gastric bubble may be inflated through a self sealing valve mechanism that seals itself when an inflation device (e.g., an inflation tube or catheter) is withdrawn from the valve. The valve m...

second embodiment

[0016]As shown in FIG. 2, a gastric balloon 200 according to the invention includes a net or bag 204 which, after insertion into a desired portion of the GI tract (e.g., the stomach), is filled with a filler material until the balloon 200 takes up a desired volume. The filler material preferably comprises string or a similar material easily inserted into and removed from the GI tract via the mouth. The net 204 includes a tether end 202 which is coupled to the filler material to facilitate grasping by a retrieval device inserted via an endoscope for removal of the filler material from the body. The net 204 may be formed as a porous netting or a fluid / gas barrier depending on a degree of desired interactivity between the stomach contents and the balloon 200. A higher degree of porosity may result in faster transport of materials through the stomach while a lower porosity may impede material transport. The net 204 may include one or more preformed failure zones. For example, the net 20...

Abstract

An obesity treatment device comprises a filament filler material movable between a substantially straight insertion / removal configuration and an operative configuration in which the filament extends along a predetermined curve to occupy a selected volume within the stomach and a retrieval device connected to a proximal end of the filler material facilitating grasping and withdrawal of the filler material. A method of treating obesity, comprises inserting to a desired position within the GI tract a filament filler in a substantially straight configuration and moving the filler into an operative configuration in which the filler curves along a predetermined path to define a desired volume in combination with, after a predetermined treatment period has elapsed, collapsing the filler into the substantially straight configuration for trans-oral removal.

Description

PRIORITY CLAIM[0001]This application claims the priority to the U.S. Provisional Application Ser. No. 60 / 910,356, entitled “GASTRIC FILLER DEVICES FOR OBESITY THERAPY” filed Apr. 5, 2007. The specification of the above-identified application is incorporated herewith by reference.BACKGROUND[0002]The incidence of obesity is rapidly increasing in industrialized countries and methods and procedures to control the weight of obese individuals is receiving ever increasing attention. In addition to diets and other lifestyle changes, aggressive medical procedures are available to limit caloric intake. Many procedures limit the amount of food digested by, for example, blocking or bypassing portions of the gastro intestinal (GI) tract. Other procedures focus on generating feelings of satiety after ingestion of reduced quantities of food.[0003]One such treatment involves placing a filler material within the stomach, often through the esophagus. The filler material takes up room in the stomach, ...
