Abstract

Certain embodiments of the present invention concern an implantable electrode line having a proximal and a distal end, an outer electrode line surface and an electrode line longitudinal axis. The implantable electrode line is characterized in that the electrode line in the region of the distal end has 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. The microstructure is formed by a plurality of microstructure elements which are arranged on the electrode line surface and which are distributed over the surface region both in the longitudinal direction and also in the peripheral direction and which have a component extending radially, wherein the microstructure elements are of a radial extent which is a fraction of the electrode line diameter. The microstructure elements are adapted, upon contact with a vessel wall, to counteract displacement of the electrode line along the electrode line longitudinal axis.
