End of Programmed Service

The Spectra WaveWriter SCS System IPG software is programmed to end service after 12
years. As the IPG nears the end of the programmed period, the Remote Control and Clinician
Programmer provide the following indicators to inform the user that the end of the programmed
period is approaching:
• Remote Control - Approximately six months before the end of programmed period, the
Remote Control displays a weekly message indicating the number of service days
remaining. Approximately one month before the end of the programmed period, the
message displays daily.
• Clinician Programmer - When less than six months of service remain, an indicator displays
on the Connect screen of the Clinician Programmer. When end of the programmed period
has been reached, a message displays when connecting to the Stimulator to indicate that
end of the programmed period has been reached and programming is not allowed.
Patients should contact their health care provider upon first receiving a message regarding the
number of service days remaining.

IPG Battery Life

The rechargeable battery in the Spectra WaveWriter SCS System IPG should provide at least
five years and up to 25 years or more of service.
settings and conditions. In most cases, the Stimulator will need to be recharged at intervals
ranging from once a week to once a month. Over time, the IPG battery will need more frequent
recharges. Like all rechargeable batteries, use over time and repeated recharge cycles reduce
the maximum charge capacity of the IPG battery.
The expected years of battery operation are defined as the longer of either:
1
A. Typical case: the time at which therapy cannot be maintained with daily charging.
OR
B. High energy case: when the maximum recharge interval has decreased by more than 50 % from the initial recharge
interval.
Battery life is dependent on your stimulation
