Abstract

The present invention relates to a percutaneous intragastric balloon catheter for the treatment of obesity. The invention occupies a portion of the gastric cavity causing a feeling of satiety and decreasing the consumption of food by an obese patient. This invention consists in a percutaneous intragastric balloon that is placed in a non-surgically form. The percutaneous intragastric balloon catheter is collocated by percutaneous endoscopic gastrotomy (PEG). The invention comprises an affixed valve for regulating the amount of fluid introduced or evacuated from the percutaneous intragastric balloon.

Claims

1. A percutaneous intragastric balloon catheter for the treatment of obesity that occupies a segment of the stomach volume, said device comprising:

a percutaneous intragastric balloon shaped for occupying a portion of the gastric cavity;

a fillant catheter connected to said percutaneous intragastric balloon for repeated filling and emptying with a fluid and as means for supporting two anchors and a valve;

two anchors, external and internal, for providing suitable surfaces that prevent movement of the percutaneous intragastric balloon catheter while in the gastric cavity;

a valve for controlling the amount of fluid introduced or evacuated from the percutaneous intragastric balloon through the fillant catheter;

a detachable cover that envelopes the extreme end of the valve, which connects with the fillant device, during the placement procedure; and

,

a fillant device that is loaded with the appropriate amount of fluid for filling the percutaneous intragastric balloon.

2. The percutaneous intragastric balloon catheter of

claim 1

, wherein said percutaneous intragastric balloon, in its non-inflated position, is covered with a plastic membrane during the placement procedure.

3. The percutaneous intragastric balloon catheter of

claim 1

, which is easily positioned into the stomach through the “

Pull”

or “

Push”

technique, a preferred embodiment is by Percutaneous Endoscopic Gastrostomy (PEG); and

withdrawn by endoscopy.

4. The percutaneous intragastric balloon catheter of

claim 1

, wherein said percutaneous intragastric balloon has a smooth surface and is preferably constructed of a durable and biocompatible material, such as surgical grade latex rubber.

5. The percutaneous intragastric balloon catheter of

claim 1

, wherein said fillant catheter is non-rigid, circular and made of a plastic material.

6. The percutaneous intragastric balloon catheter of

claim 1

, wherein said fluid may be a gas, liquid, gel or a mixture thereof.

7. The percutaneous intragastric balloon catheter of

claim 1

, wherein a filament or thread is positioned on the surface of said valve and underneath said detachable cover as means for facilitating the placement procedure.

8. The percutaneous intragastric balloon catheter of

claim 1

, wherein said external anchor is collocated on the abdominal wall after the placement procedure.

9. The percutaneous intragastric balloon catheter of

claim 1

, wherein said fillant device may be a pump or a hypodermic syringe.
