Abstract:
Gastric band fitted around a stomach wall (P3) constituted by a vertical separation of the stomach on the side of the internal curve in the proximal section, then sutured in order to create a small cavity (P1) and a cavity (P2) with the rest of the stomach, the band (1) being made of an elastically distortable material as a tube the entire length of which has a flat edge (1a) intended to bear against the stomach wall (P3) to be restricted, characterized in that the band comprises fittings (1d) that enable the band to be firmly secured to said stomach wall via sutures (3) after distortion of the band,and in that the diameter of the passage between the two cavities thus defined is set using suture threads (4) that are introduced into the band and tied at each end of said band after a calibrating apparatus (CA) has been introduced via the oesophagus, and in that the longitudinal orifice (1b) extending through the length of of the band communicates with a central orifice (1c) formed the in a side of the band opposite the flat edge (1a), in order to introduce the non-resorbable suture threads (4) the rear ends of which are tied or otherwise connected to the zone around said orifice and leave by the ends of the band in order to be tied to enable said band to be fastened into position.
