System for neuromodulation

A system for neuromodulation of nerves and configured to be implanted in a human body and having electronic signal generating means provided in an implantable signal generator housing (10),

• the system comprising:
• voltage supply means connected or connectable to the signal generating means,
• at least one elongated multi-channel wire electrode means (12) connected or connectable to the signal generator housing and configured for implantation in the human body on a nerve (DNP), said multi-channel wire electrode means comprising a plurality of shell segment electrodes (16a-16d) on a nerve contact area (14) and, on ends thereof, being provided with fixing means (18) for anchoring the wire electrode means to an implantation location,
• the signal generator housing having a flat fixing section (20) which sits and/or protrudes in the manner of a flange and/or a piece of tissue and which allows for surgical fixation of the signal generator housing to a tissue, muscle or bone area (PB) in the body, to a muscle portion and/or to a fascia, and
• sleeve-like, curved electrode wire guide means (28) comprising a sleeve-shaped guide section (26) and a handle (24) attached to the sleeve-shaped guide section (26) at one end, wherein the handle (24) has an outside diameter that is greater than an outside diameter of the sleeve-shaped guide section (26);
• wherein the sleeve-shaped guide section can be manually operated via the handle (24), for penetrating tissue of the human body from the extracorporeal at an implantation area, and for guiding the wire electrode means (12) in the sleeve-shaped guide section (26) of the electrode wire guide means and, for inserting the wire electrode means (12) into the sleeve-shaped guide section (26) from the intracorporeal,
• wherein the curved electrode wire guide means (28) further comprises a mandrel (30) which can be inserted into the sleeve-shaped guide section and which can be detached from an end portion on the body side of the electrode wire guide means, opposite to the handle, by pulling out when the curved electrode wire guide means are inserted into the body.
