Balloon system and methods for treating obesity

摘要

A medical system for the treatment of morbid obesity comprising an inflatable balloon implanted in a gastric cavity, a percutaneous fillant delivery tube and a control module connected to the tube for regulating the inflation and deflation of the balloon. The balloon may be individually contoured and inflated to occupy a large volume of the gastric cavity to provide a feeling of satiety. The balloon may also be deflated to give the gastric cavity lining a rest during less critical time.

1. A method of treating obesity, the method comprising:
transferring a biocompatible fillant to a gastric device in a gastric cavity to inflate the gastric device, wherein the gastric device comprises—
an inflatable balloon; anda fillant delivery tube extending through the inflatable balloon, wherein a proximal end portion of the fillant delivery tube is connected to a first portion of the balloon and a distal end portion of the fillant delivery tube is connected to a second portion of the balloon spaced apart from the first portion, and wherein the fillant delivery tube is configured to impart a reference shape to the balloon in a deflated state and axially constrain the balloon in an inflated state;wherein the biocompatible fillant is transferred to the balloon via the proximal end portion of the fillant delivery tube;wherein transferring the biocompatible fillant to the balloon further comprises automatically fully inflating the balloon to a predetermined size with a predetermined volume of the biocompatible fillant; andwherein the inflatable balloon comes in contact with a major portion of the gastric cavity when the balloon is in the inflated state such that an outer surface of the inflatable balloon contacts an inner surface of the gastric cavity.
