Electrode line

An implantable electrode line comprising:

• a proximal end;
• a distal end;
• an outer electrode line surface;
• and
• an electrode line longitudinal axis,
• wherein the electrode line in a region of the distal end includes a surface region with a microstructure, the surface region being provided for lateral contact with a vessel wall and being arranged at a spacing relative to the distal end which measures a plurality of electrode line diameters, and wherein the microstructure is formed by a plurality of microbristles which are arranged on the electrode line surface and which are distributed over the surface region both in a longitudinal direction and also in a peripheral direction and which have a component extending radially, wherein the microbristles are of a radial extent which is a fraction of the electrode line diameter and are adapted, upon contact with a vessel wall, to counteract displacement of the electrode line along the electrode line longitudinal axis.
