Creating or Modifying a Program
To create a new Program or modify an existing Program, select the Program button and choose one of the four Programs from the drop‑down
arrow. The system allows you to configure up to four Programs on a Stimulator.
For a given Program, you can view and/or adjust several options via the Program Options button. The Program Options include the following:

Description
1
Battery
For a non‑rechargeable Stimulator, the Energy Use Index for the current Program is displayed. This value is
used to provide an estimate of battery longevity for the non‑rechargeable Stimulator on the current Program.
See the
section of this manual for more information.
For a rechargeable Stimulator, an Estimated Charge Time for the current Program is displayed. This value
provides an estimate of the duration and frequency of charging necessary to maintain stimulation.

Ramp
Time to gradually increase the stimulation from zero to the programmed Amplitude when stimulation is turned
ON.

Selecting Stimulation Areas
For a given Program, you may configure up to four Areas. With a new Program, an Area will be automatically assigned to each brain hemisphere
and named based on the defined Target and side of the brain selected in the
Configure Tab
. You may add an additional Area by selecting
an empty Area (+) and choosing a configuration (e.g. Left STN). You may reassign an Area by first selecting
Options
for that Area and then
choosing
Delete Area
. You may then select a different hemisphere configuration.
Note:
Predefined simulations may be imported from Elements by selecting Load Simulation from the Area Options button.
Selecting Contacts
You can manually assign anodes and cathodes in
Custom Mode
or incrementally steer a stimulation field along the Lead in the
Steering Mode
.
Steering Mode is limited to a monopolar configuration of either a single cathode or adjacent cathodes.
To provide anodic stimulation, you must use
Custom Mode
. You may assign the Stimulator Case and all the Contacts as anode or cathode
individually in Custom Mode. The External Trial Stimulator (ETS) is limited to
Custom Mode
since the Stimulator Case cannot be assigned as a
cathode or anode.
Note:
Switching from Custom Mode to Steering Mode will clear the Contact and Stimulator Case assignments.
Note:
Stimulation using multiple independent current control (MICC) with a Directional Lead is referred to as Cartesia 3D.
Note:
Stimulation with only Lead Contacts assigned as anode(s) and the IPG case assigned as cathode is referred to as Monopolar Anodic
Stimulation (MAS).
