Steering Mode
Steering Mode is a simplified programming mode where the Contact(s) act as the cathode(s) and the Stimulator Case acts as the anode.
This mode allows you to steer a monopolar cathode along the Lead, eliminating the need to turn ON and OFF individual Contacts. Steering
Mode incrementally shifts a percentage of the cathodic current to the adjacent Contact(s) using current steering technology to create smooth
transitions between Contacts.
The DB‑2201 Standard Lead has eight ring Contacts per Lead, labeled 1 through 8 on each Lead.
To Steer along the DB‑2201 Standard Lead:
1.
Select
Steering Mode
.
2. Select a Contact to assign it as a 100% cathode.
3. Use the
and
buttons to incrementally steer the stimulation focus along the length of the Lead. The amount of cathodic current
will shift in 10% increments.
Note:
You may also adjust directly from one Contact (Level) or half level to another. The Amplitude for the selected Area will drop to
0 mA when another Contact is selected, but not when steering in 10% increments.
The DB‑2202 Directional Lead has a total of eight Contacts per Lead, labeled 1 through 8 on each Lead. Contacts 1 and 8 are the distal tip and
proximal ring Contacts, respectively, while Contacts 2 through 7 are the small directional Contacts (segments) grouped into two rows of three
segments each.
To Steer along the DB‑2202 Directional Lead:
1.
Select
Steering Mode.
2. Select a Contact to assign it as a cathode. You may create an equal spread of current across a Level of Contacts (“ring mode”) by
selecting anywhere within that Level, then selecting the center button. To assign a single directional segment as the cathode, select
anywhere within that Level, then select the corresponding button (Figure 15).

3. Use the
and
buttons to incrementally steer the stimulation focus along the length of the Lead.
Note:
You may also adjust directly from one Contact (Level) or half level to another. The Amplitude for the selected Area will drop to
0 mA when another Contact is selected, but not when steering in 10% increments.
4. Select one of five preset directions
for the stimulation field. The directional presets will steer the fully focused
stimulation field in one of four orthogonal directions or put the stimulation field into “ring mode.”
