Implantable electrode lead

An implantable elongated electrode lead comprising:

• an electrode body;
• at least one electrode pole connected to the electrode body;
• a connector;
• and,
• an electric supply lead which is electrically connected to the at least one electrode pole and extends from the at least one electrode pole to the connector at a proximal end of the implantable elongated electrode lead;
• wherein the electric supply lead comprises at least one deformable supply lead section, wherein said at least one deformable supply lead section is configured to assume at least one altered shape after implantation of the implantable elongated electrode lead;
• wherein each of said at least one altered shape is pre-impressed upon the electric supply lead;
• and,
• wherein said at least one altered shape is configured to provide an inductance that is higher in the at least one deformable supply lead section after deformation into said at least one altered shape than before deformation, wherein the inductance is at least 0.1 μH;
• an outer sleeve within which the electric supply lead is disposed;
• wherein the electric supply lead is disposed inside the outer sleeve such that the electric supply lead, in the at least one deformable supply lead section thereof, is deformable relative to the outer sleeve and inside the outer sleeve;
• and,
• wherein the outer sleeve is expandable in a region of the at least one deformable supply lead section, and wherein the at least one deformable supply lead section and outer sleeve are configured such that the outer sleeve expands radially in all directions in the shape of a balloon upon deformation of the at least one deformable supply lead section;
• and,
• wherein the electric supply lead further comprises an electric conductor which is enclosed by a jacket at least in the region of the at least one deformable supply lead section, upon which the at least one altered shape of the supply lead is pre-impressed.
