Abstract

For communicating information between a medical implant in a patient's body and an external communication unit (9) located outside the patient's body the medical implant is connected to or comprises an internal communication unit (11). The external communication unit and the internal communication unit communicate with each other using part of the patient's body as a communication path, in particular as an electrical signal line. The communication path between the receiver and the external energizer can be established using a capacitive coupling, i.e. the information can be capacitively transferred over a capacitor having parts (1, 3) located outside and inside the patient's body.
