The invention relates to an implantable device suitable for being fixed in a fixation position to a wall of a patient's stomach, the implantable device being accommodated in the stomach when the implantable device is in the fixation position, the implantable device being characterised in that it comprises a reserve of an active substance and an injector suitable for administering the active substance to the patient.

Implantable device

The device, that can be implanted in the intestinal cavity, comprises a reactor comprising a semi-permeable or porous membrane or coating linked to a element for attachment to an intestinal or gastric wall. The reactor can be in the form of a ribbon, a structure having more than two faces or an open structure delimiting a lumen, comprising, or formed from, a semi-permeable or porous membrane. The reactor can also delimit, at least partially with the semi-permeable or porous membrane of same, a closed inner space. The reactor can comprise or carry enzymes or micro-organisms, in particular bacteria or yeast. The reactor is used for generating a chemical reaction with one or more molecules present in the intestine, or for producing one or more biologically active molecules. It can, in particular, be used for consuming sugars, disaccharides and simple sugars or producing essential amino acids or other molecules having a positive effect on the health.
