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.
