Abstract

A method for controlling the body weight of a patient employs a percutaneous intragastric balloon catheter (10). The method comprises the first steps of inserting a percutaneous intragastric balloon catheter (10) into the stomach of the patient through a gastrostomy tract. The intragastric balloon catheter (10), in turn, comprises elongated shaft means (11) having first (12) and second (13) ends, a first inflatable balloon (14) carried proximal to the first end; a second inflatable balloon (15) carried proximal to the first inflatable balloon, the second balloon having a lesser inflated volume than the first balloon; first and second inflation lumens (18, 20); first and second inflation ports (22, 23) communicating respectively with the first and second inflation lumens and the first and second balloons, which ports are carried by the second end (13); a drainage lumen (16) passing between said first and second ends. The method continues by inflating the first and second balloons within the patient, partially filling the stomach to provide satiety. The intragastric balloon catheter employed is also deemed to be novel.

Claims

1. A method for controlling the body weight of a patient comprising the steps of:

inserting a percutaneous intragastic balloon catheter into the stomach of the patient through a gastrostomy tract;

said intragastric balloon catheter comprising

elongated shaft means having first and second ends;

a first inflatable balloon carried proximal to said first end;

a second inflatable balloon carried proximal to said first inflatable balloon, said second balloon having a lesser inflated volume than said first balloon;

first and second inflation lumens;

first and second inflation ports communicating respectively with said first and second inflation lumens and said first and second balloons, said ports being carried by said second end; and

a drainage lumen passing between said first and second ends; and

inflating said first and second balloons within the stomach of the patient, partially filling the stomach, to provide satiety.

2. A method, as set forth in claim 1, including the additional step of allowing said gastrostomy tract to mature for at least four weeks.

3. A method, as set forth in claim 1, including the additional step of anchoring said intragastric balloon catheter outside the body of the patient with external retaining means carried distally of said second end.

4. A method, as set forth in claim 1, further comprising the steps of:

retrieving said intragastric balloon catheter; and

replacing said intragastric balloon catheter.
