Contacting method and system

1. A system for reception or emission of an electrical signal from or into the human or animal body, comprising:

at least one insulated electrical conductor;

a sleeve-shaped ring electrode that is electrically connected to the electrical conductor and comprises an internal side, an external side, a channel; and

an opening in a wall of the channel, wherein the opening has a smaller diameter at the external side than its diameter at the internal side;

wherein the channel defines a longitudinal axis along which the conductor is arranged in the channel;

wherein a material of the ring electrode surrounds the entire circumference of the opening;

wherein the electrical conductor is guided through the opening between the internal side and the external side of the opening transverse to the longitudinal axis of the channel;

wherein the electrical conductor is connected and fixed to the ring electrode within the opening directly in firmly-bonded or force-locking manner such that a durable mechanical and electrical connection between the electrical conductor and the ring electrode is established and such that no portion of the electrical conductor extends beyond the external side of the ring electrode; and

wherein, other than the direct connection between the conductor and the ring electrode, there is no further component present that supports the connection of the electrical conductor to the ring electrode in order to establish a mechanical connection in between.

2. The system according to claim 1 , wherein the firmly-bonded connection is a welded connection.

3. The system according to claim 1 , wherein the electrical conductor is connected to the ring electrode in a firmly-bonded, but not in a force-locking manner.

4. The system according to claim 1 , comprising a multitude of electrical conductors that are each insulated with respect to each other and are arranged in the channel along the longitudinal axis, wherein the ring electrode surrounds multiple or all of the conductors.

5. The system according to claim 4 , comprising a multitude of ring electrodes, which each are electrically connected to exactly one other of the electrical conductors, such that the ring electrodes can be electrically addressed independent of each other.

6. The system according to claim 1 , wherein the opening extends through the ring electrode going from the internal side to the external side.

7. The system according to claim 6 , wherein the electrical conductor is guided through the opening from the internal side to the external side such that one end of the conductor is flush with the external side.

8. The system according to claim 1 , wherein the opening has a varying diameter that is cone-shaped.

9. The system according to claim 1 , further comprising at least one further opening.

10. An electrical medical device comprising a system according to claim 1 .

11. The electrical medical device according to claim 10 that is at least one of a lead, a pulse generator, a cardiac pacemaker, a cardiac resynchronisation device, a sensor and a stimulator.

12. A method of treatment of a human or animal body, comprising the emission of an electrical signal by the system according to claim 1 .
