Abstract
Techniques whereby electrical stimulation to treat symptoms from central and peripheral nervous system disorders such as those found in e.g. Parkinson'"'"'s disease, epilepsy, psychiatric illness and intractable pain, using a quadripolar deep brain stimulation electrode connected to an implantable pulse generator have been expanded. By an implantation of an electrode, it is important for the outcome to determine the optimal placement of the electrode. By the invention, an electrode device is provided allowing stimulation of a large volume of neural tissue in combination with simultaneous microelectrode recording. Other improvements involve a temporary electro-physiological microrecording microelectrode/stilette 1, a bent electrode tip, a split electrode tip or an asymmetrical electrical stimulation field. This technique allows for a less traumatic localisation of the optimal neural stimulation area by microelectrode recording in combination with the placement of the permanent deep brain stimulation electrode.
