The invention concerns a novel medical system intended to be fixed in a surgically prepared osseous site of a patient and that connects external components to active entities located inside the body of the patient.External components and active entities are designed to store, emit and/or transfer a specific flow, such as a flow of electricity, data, fluids, solids or light.The external components can be housed in an external housing and bound to active entities being located within the body of the patient through connection elements located within a percutaneous abutment, an implant and possible additional implanted means of connections and/or stimulations.
