Brain stimulation electrode line and insertion device for brain stimulation electrode lines

摘要

The invention relates to a brain stimulation electrode line (10) for electric stimulation of the brain areas with an elongated flexible electrode line body (12) having on or near its distal end at least one stimulation electrode (18) designed for delivering electric pulses to surrounding body tissue in the event of use. The brain stimulation electrode line (10) is characterized in that the electrode line body has on its distal end at least one ultrasonic transducer (20), which is arranged so that it can detect reflected ultrasound in a detection range aligned distally along the longitudinal direction of the electrode line body (12).
