Abstract: 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.

Abstract: 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.

Abstract: The invention relates to an implantable system (10) comprising a first device (20), called a centralization device, which is able to be fixed in a fixation position to a wall of the stomach of a patient, the centralization device (20) being received in the stomach when the centralization device (20) is in the fixation position, and at least one second device (25). The implantable system (10) is characterized in that the centralization device (20) comprises a controller (45), an electrical supply (55) and an emitter/receiver (60) to permit communication between the centralization device (20) and the second device (25) when the second device (25) is in a functioning position, the second device (25) being situated outside the body of the patient when the second device (25) is in the functioning position.

Abstract: An implantable system comprising a first device, also called a centralisation device, suitable for being implanted in a fixation position inside the patient's body and at least one second device suitable for stimulating an organ of the patient when the second device is implanted, in a stimulation position, in the patient's body. The first device being further configured to command a stimulation of the organ by the second device. The implantable system being characterised in that the organ is a separate organ from the stomach and in that, when the first device is in the fixation position, the first device is accommodated in the patient's stomach and fixed to a stomach wall.
