Physician’s Manual — VNS Therapy Programming Software (8.1)
For Models 103, 104, and 105 Generators, if an interruption occurs during
a System or Generator Diagnostics test, the Programming Software
displays an error message indicating that the procedure failed and then
proceeds to display the test result (Fault). An interrogation is
recommended after a failed System or Generator Diagnostics to verify
device settings.
4.2.2.2.
Diagnostic test parameters
There are 14 test parameters for the diagnostics tests:
1.
Patient ID:
This parameter is a three-character alphanumeric code
selected by the physician and programmed into the Pulse Generator.
2.
Model ID:
Model designator of the Pulse Generator being
interrogated.
3.
Serial Number:
This parameter is a numeric code assigned to the
Pulse Generator and programmed into the Pulse Generator by
LivaNova.
4.
Implanted:
This parameter represents the implant date as
programmed by the physician.
5.
Communication:
This parameter is an indicator of the
communication status during diagnostics. Table 4 shows the possible
values and interpretation for the communication parameter. If the
communication indicator shows the “FAULT” message, an error has
occurred during a communication. The error may be the result of
improper positioning of the Programming Wand over the Pulse
Generator, of EMI or noise being sensed by the System, or of a
depleted battery in the Programming Wand or Pulse Generator.
Information on overcoming EMI, repositioning the Programming
Wand, and resolving wand battery problems can be found in the
physician’s manual for the Programming Wand. An explanation for
detecting when a Pulse Generator has reached end of service is found
in the physician’s manual for the VNS Therapy Pulse Generators.
