1. An implant system, comprising:
- a) a medical implant having a support, fixation, or hold function formed at least in part from a metal material that can be degraded by the body of the implant wearer, andb) a control device for controlling the degradation behavior of the medical implant, the control device having(i) at least one counter-electrode to the medical implant, the counter-electrode separate from the medical implant, and(ii) a voltage source adapted to apply a polarization voltage (Δ
U) between medical implant and counter-electrode, to control the degradation behavior of the medical implant.

Abstract
An implant system comprising a functional implant (5, 6) that fulfills a medical function, particularly a bone implant, which is formed at least in part of a metal material that can be degraded by the body (2) of the implant wearer, as well as a control device (7) for controlling the degradation behavior of the functional implant (5, 6). The control device (7) has a counter-electrode (10) to the functional implant (5, 6), and a voltage source (8) for making available a polarization voltage (ΔU) between functional implant (5, 6, 15) and counter-electrode (10), to control the degradation behavior of the functional implant (5, 6).

16. An implant system, comprising:
-
a) a medical implant formed at least in part from a metal material that can be degraded by the body of the implant wearer, and b) an implantable control device for controlling the degradation behavior of the medical implant, the control device having (i) at least one implantable counter-electrode to the medical implant, the counter-electrode separate from the medical implant, and (ii) an implantable battery adapted to apply a first polarization voltage (Δ
U) between the medical implant and the counter-electrode to reduce or prevent degradation of the medical implant at a first time and a second polarization voltage less than the first polarization voltage to increase degradation of the medical implant at a later time. - View Dependent Claims (17, 18, 19)
