Claims20
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.
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 the device (31) is adapted to create a repetitive mechanical constraint by cyclic deformation of the mechanical stimulation means (35),
- wherein a shape and a size of constitutive components of said device (31) are adapted for inserted mounting within a wall (28) of a gastrointestinal organ,
- wherein at least a part of the mechanical stimulation means (35) has a surface extension, able to cover a substantial part of the wall (28), the part of the mechanical stimulation means (35) having the surface extension also having a relative stiffness when not activated, and
- wherein the mechanical stimulation means (35) comprises at least one piezoelectric element (92).
