ABSTRACT:
An electrode device for intracorporeal stimulation of body tissue, in particular for intracardial stimulation of heart tissue, has an electrode cable containing a coiled, flexible, insulated first wire running along substantially the entire length of the electrode cable and whose interior forms a channel, with at least one partially conductive electrode head provided on the distal end of the electrode cable. The cable also contains a second wire provided in the channel, this second wire running coaxially along the entire length of the electrode cable and being attached at or near the distal end of the electrode cable. The proximal end of the second wire extends beyond the proximal end of the electrode cable, a device for displacing the second wire in relation to the electrode cable in a selected way is provided so that by compressing the coiled first wire the electrode cable can be made stiff or pliant, as desired, with the need for a stylet.
