Cross-programming (applicable to Model 100,
101, and 102 Pulse Generators ONLY)
Models 100, 101, and 102 Pulse Generators are susceptible to an event
known as cross-programming, where parameter settings from one patient's
Pulse Generator are inadvertently programmed to another patient's Pulse
Generator. Cross-programming occurs when all the following conditions
are met:
1. Patient A is implanted with the same model Pulse Generator as Patient
B
2. Patient A's Pulse Generator was interrogated/programmed with the
Programming Software and the Programming Software is left on the
PARAMETER screen
3. Inactivity timeout has not expired, or is disabled
4. Patient B's Pulse Generator is programmed at the PARAMETER
screen in step 2 without first performing an interrogation
The result of the above scenario is that Patient B's output current and
magnet output current settings are programmed to Patient A's output
current and magnet output current settings, unless those parameters values
were changed as part of step 4. In addition, the Programming Software
database will incorrectly indicate Patient A to be programmed to setting
changes made in step 4. Table 3 gives an example of cross-programming
