Abstract

The invention concerns an intragastric device inserted by endoscopic path into a patient'"'"'s stomach (2) pertaining to a device assembly (1) comprising each a balloon or envelope (3) having a specific nominal volume sealingly connected to connecting means consisting of a disc (6) forming a support base for the balloon (3) against the inner wall of the stomach (2), a flexible tube or catheter (7) for connecting the balloon (3) to a filling device (4, 5), and catching means (9) integral with the tube or catheter (7), said connection means enabling to set and/or remove the balloon (3), and to fix either inside the patient'"'"'s body or subcutaneously the filling (4, 5), to be able to bring the balloon or envelope (3) to its predetermined nominal volume.

Claims

1. An intragastric device introduced by an endoscopy procedure into the stomach (2) of a patient for treating morbid obesity, characterized in that it is made up of a set of devices (1) each comprising a balloon or envelope (3) of defined nominal volume which is connected in a leaktight manner to connection means consisting of a disk (6) forming a support base for the balloon (3) against the inner wall of the stomach (2), a flexible tube or catheter (7) for connecting the balloon (3) to a supply device (4, 5), and securing means (9) integral with the tube or catheter (7), said connection means making it possible, on the one hand, to position and/or recover the balloon (3) and, on the other hand, to fix the supply device (4, 5) either outside the patient'"'"'s body or subcutaneously, in order to be able to bring the balloon or envelope (3) to its defined nominal volume.

2. The intragastric device as claimed in claim 1, characterized in that the disk (6) is positioned about the tube or catheter (7) and against the outer wall of the balloon or envelope (3).

3. The intragastric device as claimed in claim 2, characterized in that the balloon or envelope (3) is fixed about the tube or catheter (7) so that the latter opens out inside said balloon.

4. The intragastric device as claimed in claim 1, characterized in that the securing means (9) consist of a joining piece (11) of conical profile integral with a filament (8).

5. The intragastric device as claimed in claim 4, characterized in that the joining piece (11) has a stub (12) which penetrates inside an internal bore (13) of the tube or catheter (7).

6. The intragastric device as claimed in claim 4, characterized in that the filament (8) has a straight or looped profile.

7. The intragastric device as claimed in claim 1, characterized in that the disk (6) is of circular shape.

8. The intragastric device as claimed in claim 1, characterized in that the disk (6) is of oval shape.

9. The intragastric device as claimed in claim 1, characterized in that the balloon or envelope (3) has an oval profile or other profile which is symmetrical with respect to the horizontal axis of the tube or catheter (7).

10. The intragastric device as claimed in claim 1, characterized in that the balloon or envelope (3) has an oval profile or other profile which is asymmetrical with respect to the horizontal axis of the tube or catheter (7).

11. The intragastric device as claimed in claim 1, characterized in that the balloon or envelope (3) has a kidney-bean-shaped profile symmetrical with respect to the horizontal axis of the tube or catheter (7).

12. The intragastric device as claimed in claim 1, characterized in that the balloon or envelope (3) has a kidney-bean-shaped profile asymmetrical with respect to the horizontal axis of the tube or catheter (7).
