Additional Information
Stimulator Programmable Characteristics
The stimulation parameters are independent for each DBS Lead such that stimulation of different brain targets can have different Amplitudes,
Pulse Widths, Stimulation Rates, and Contact configurations. It is possible to configure one Lead as monopolar, and one as multipolar. It is also
possible to configure a single Lead with both monopolar and multipolar Areas.
The programmable parameter ranges for the Stimulator are shown below.

1
The programmable coverage for each individual Contact is limited to 12.7 mA. A programming interlock is enforced to limit the total output
current to 20 mA or less per coverage Area. For example, a maximum current output of 12.7 mA on one Contact would limit the total summed
current output on the remaining Contacts to 7.3 mA within one coverage Area.
2
The Rate is limited to 255 Hz for a given Area. The global Rate limit for each Lead is also 255 Hz.
3
The use of lower Pulse Widths than established (60 to 450 μsec) is the sole responsibility of the user.
