This gastric ring comprises a band which is able to surround the wall of
the stomach, and means with which it is possible, after implantation, to
modify the cross section of the opening delimited by the ring.
According to the invention,
the band comprises at least one zone made of a material which is
elastically deformable in the longitudinal direction of this band;
said zone has at least two bearing points formed on it at two locations
separated in the longitudinal direction of the band, and
the ring comprises at least one rigid element made of a bioabsorbable
material and bearing against said zone in the area of said bearing
points, this rigid element, before absorption, making it possible to
maintain said bearing points at a distance from one another different
than the distance separating these two bearing points in the absence of
elastic deformation of said zone of the bands, and, after absorption, no
longer forming an obstacle to the return of said zone of the band to its
nondeformed state.
