Figure 7: Example Schedule
Click on the “Edit…” button in the Schedule window to set and adjust time of day when therapy will be
delivered. The Schedule contains a list of entries. Each entry is defined by a time period and the Therapy
assigned to it. “Off” should be selected if periods of no therapy are desired. Click Save to program
Schedule changes or “Cancel” to ignore changes.

Note: The IPG Schedule is in relation to the local time set by the programmer computer. Patients who
travel to other time zones and have more than one therapy in their Schedule will experience therapy
transitions based on the time zone in use at the time of IPG programming. If the patient travels to a different
time zone, the IPG schedule does not change to the new time zone. Clinicians should take this behavior into
consideration when programming multiple therapies.IPG Diagnostics.

Use the “IPG Diagnostics…” button on the Main Screen to navigate to the Management Center screen.
This screen provides the following information:
This screen provides the following information:
o
Versions of embedded firmware
o
The date and time EOS was encountered (N/A if EOS has not occurred).
o
The times of the measurements of the maximum and minimum battery voltages.
For troubleshooting purposes, CVRx can request users to press the “Save IPG Diagnostics” button.
Estimating Longevity of Implantable Pulse Generator
The battery lifetime of the IPG is dependent on device therapy settings. For example, a 24-hour therapy
with 20 Hz therapy frequency, bilateral output pathway, 500 µs pulse width, and 6.0mA pulse amplitude
into a 600 Ohm load will yield estimated device longevity of approximately 20 months. Follow-up
frequency for each patient should be adjusted based on the longevity results of each follow-up such that the
next follow-up occurs no later than half of the number of months to predicted RRT when RRT is greater
than 3 months away. When RRT is less than 3 months away, it is recommended that replacement be
scheduled on or before the RRT to prevent battery depletion.

Table 2 contains the estimated device longevity for a variety of parameter sets. For these calculations, a
500µs pulse width and single 24-hour therapy was assumed.
