Stimulator Programmable Characteristics

The stimulation parameters are independent for the two DBS Leads such that stimulation of two
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, as long as the same contacts are
not used in both.
The programmable parameter ranges for the Stimulator are shown below.

(4 Programs with 4 Areas per Program)
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.
3
The use of higher frequencies than the ones that are established (250 Hz) is the sole responsibility of the user.
4
The use of lower pulse widths than established (60-450 μsec) is the sole responsibility of the user.
Note: While it is possible to program stimulation rates higher than 255 pps, clinical
effectiveness and safety of these cumulative rates has not been demonstrated and
is not recommended.
