Abstract

A contacting device for electrical connections to flexible electrode lines insertable or implantable into a patient body, includes a line coil with a plurality of coradially bundled coil wires, an inner fixing sleeve for a partial bundle of the coil wires, the fixing sleeve has a through-slit running in the axial direction for the partial bundle of the coil wires, and a winding groove running in the peripheral direction for the partial bundle led through, an outer electrode sleeve sitting on the inner fixing sleeve and electrically contacted with the partial bundle, and a strain-resistant fixing between the fixing sleeve and the partial bundle guided through the through-slit via an application of force on the partial bundle by pressing the fixing sleeve onto the line coil to produce plastic deformation and by looping the led-out partial bundle around the fixing sleeve in the winding groove by a minimum looping angle.
