The invention relates to a device (10) for polarizing at least two spatially separated, at least partially electrically conductive implants (12, 14, 16, 18), comprising a coil (20), which has a first pole (22) and a second pole (24), a first contact device (26) associated with the first pole (22) for electrically contacting a first implant (12), a second contact device (28) associated with the second pole (24) for electrically contacting a second implant (14, 16, 18), wherein the coil (20) can be arranged directly or indirectly on or in the first implant (12) and carried by said first implant and - wherein the second contact device (28) comprises a flexible electrical line (30), which allows the second implant (14, 16, 18) to be contacted so that the coil (20) can be arranged in a spatially separated manner from the second implant (14, 16, 18).
