An implant system comprises a a medical function of serving a function of the implant (5, 6), in particular a bone implant, the at least partially of a from the body (2) of the implant carrier are decomposable metal material is formed, as well as a control means (7) for controlling the degradation behavior of the function of implant (5, 6). , Said control means (7) has a counter electrode (10) to the function of the implant (5, 6) and a voltage source (8) for providing a bias voltage (u) between the function of the implant (5, 6, 15) and counter electrode (10) for controlling the degradation behaviour of the function of implant (5, 6) on.
