Adaptation probe for insertion into implanted electrode devices of active medical implants and set composed of an implantable electrode device and an adaptation probe

An adaptation probe for insertion into implanted electrode devices of active medical implants for use in high-frequency magnetic alternating fields of MRI systems comprising:

• a probe body that is elongated and flexible and configured to fit within a lumen of an electrode;
• at least one electrical assembly coupled with said probe body comprising
• an interface;
• one or more electrical components connected to said interface wherein said one or more electrical components are configured to be electrically coupled to one supply lead of a plurality of supply leads of an electrode device such that electrical properties of the electrode device are configurable, wherein said electrical properties comprises any combination of one or more of frequency-dependent resistance, impedance, capacitance, or inductance thereof;
• a plurality of electrical contact pins comprising miniature electronic components connected therebetween, wherein the plurality of contact pins and the miniature components are all configured to be enclosed in a filter housing;
• a wire coil wound between the plurality of contact pins around the miniature electrical components configured to generate an inductance L of a high frequency filter in the filter housing;
• wherein the contact pins of the at least one electrical assembly comprise mutually insulated caps each with an interior, wherein the mutually insulated caps face one another, and the one or more electrical components of the electrical assembly are disposed in the interior;
• and
• wherein said adaptation probe further comprises an insulator insert, wherein said insulator insert is an insulating intermediate piece entirely located between said caps, and wherein each of said caps are mechanically connected by said insulator insert and each of said caps are insulated from one another by said insulator insert.
