9.5.2 CCM Signal Parameters
The CCM signal is a pulse train comprising a programmable number of
consecutive pulses, each with two phases of opposite polarity and programmable
duration. Accordingly, the common practical configuration is given by
programming CCM to be delivered for one hour every few hours, for example 1
hour ON followed by 3:48 hours OFF, repeatedly, to produce 5 hours of CCM
therapy per day.
• Number of Pulses: With the OMNI Smart Programmer software, the
number of pulses can be set to 1, 2, or 3.
• Delay: CCM signal delivery is triggered by the Local Sense event. The
delay parameter (coupling interval) is the time interval between the
leading edge of the Local Sense triggering event and the start of CCM
pulse train delivery. With the OMNI Smart Programmer software, the
delay parameter can be set to values between 3 ms and 140 ms, in 1 ms
increments. This delay range is designed to ensure that the delivery is only
within the absolute refractory period, and to avoid potential excitatory
behavior of the CCM signal.
Note: When the OPTIMIZER Smart IPG is in Active OVO-LS-CCM
mode, the maximum allowable setting for this parameter is 45 ms.
• Amplitude (Magnitude): This is the initial voltage of the CCM signal.
With the OMNI Smart Programmer software, the amplitude can be set to
values between 4.0 V and 7.5 V, in 0.5 V increments.
• Phase Duration: The phase duration of the pulses comprising the CCM
signal can be programmed with the OMNI Smart Programmer software to
one of 4 possible values between 5.14 ms and 6.60 ms. The duration of
both phases are automatically set to identical values.
• Phase Polarity: The phase polarity of the pulses comprising the CCM
signal can be programmed with the OMNI Smart Programmer software to
“Positive” or “Negative”. When the polarity of PHASE 1 is set to one
value, the polarity of PHASE 2 is automatically set to the opposite value
9.5.3 Balancing Phase
Delivery of each CCM pulse train is completed by a Balancing Phase, which
discharges any residual polarization at the electrode/tissue interface. Balancing is
accomplished by short-circuiting the channels used to deliver the CCM signal for
a period of 40 ms.
