1. An implantable device to treat obesity, said device (31) being able to create a mechanical constraint on a gastrointestinal organ wall and comprising:
an energy source (36, 92), and
a mechanical stimulation means (35),
wherein, upon activation, the mechanical stimulation means (35) undergoes cyclic deformation,
wherein the mechanical stimulation means (35) is implantable within a wall (28) of a gastrointestinal organ at an implantation site,
wherein the mechanical stimulation means (35) has a surface extension that, with the mechanical stimulation means (35) adaptable within the wall (28) at the implantation site, adaptable to cover a part of the wall (28) of the gastrointestinal organ at the implantation site,
wherein, when the mechanical stimulation means (35) is not activated, the surface extension of the mechanical stimulation means (35) has a stiffness that is adapted to provide rigidity to the part of the wall adapted to be covered by the surface extension at an implantation site, and
wherein the cyclic deformation of the mechanical stimulation means (35) creates a repetitive mechanical constraint on the part of the wall (28) adapted to be covered by the surface extension at the implantation site.
