Feedthrough device

An implantable medical device comprising:

• a housing, an electronic circuit located in the housing, and a feedthrough device provided between an interior and an exterior of inside the housing and used to transmit an electronic signal to and from the electronic circuit,
• wherein the feedthrough device includes:
• a feedthrough substrate made of an insulator and having a first surface and a second surface;
• at least one first feedthrough conductor having a first terminal exposed only to the first surface of the feedthrough substrate and a first body connected to the first terminal and not exposed to the outside of the feedthrough substrate;
• and
• at least one second feedthrough conductor having a second terminal exposed only to the second surface of the feedthrough substrate and a second body connected to the second terminal and not exposed to the outside of the feedthrough substrate, and corresponding to the first feedthrough conductor in a one-to-one manner to be paired therewith,
• wherein the first body of each first feedthrough conductor and the second body of each second feedthrough conductor corresponding thereto are arranged to be capacitively coupled with each other;
• wherein the feedthrough device is configured so that one of the first surface and the second surface is inside the housing toward the electronic circuit and another one of the first surface and the second surface is outside of the housing away from the electronic circuit;
• and
• wherein transmission of an electronic signal to and from the electronic circuit is by way of capacitive coupling between the at least one first feedthrough conductor and the at least one second feedthrough conductor.
