Pre-MRI Instructions
An appropriate healthcare professional with access to a VNS Therapy
programming system must prepare the VNS Therapy generator before the
patient enters an MR system room.
1. Interrogate the VNS Therapy generator* and record the generator settings
2. Perform System Diagnostics to ensure proper operation of the generator
3. Reprogram the Output Current parameter settings for Normal Mode,
Magnet Mode, and AutoStim Mode† as follows:
• Output Current (mA): 0.0
• Magnet Current (mA): 0.0
• AutoStim Current (mA): 0.0 and Tachycardia Detection "OFF"
4. Turn off any other optional device features (Model 1000 only)
5. Interrogate the generator* to verify that programming was successful
6. Verify that placement of the VNS Therapy system is located between the
C7 and T8 vertebrae
7. Instruct the patient to notify the MR system operator of pain, discomfort,
heating, or other unusual sensations so the operator can terminate the
procedure, if needed
Post-MRI Instructions
After the MRI procedure, an appropriate healthcare professional with access to
a VNS Therapy programming system should assess the condition of the VNS
Therapy system.
To assess the VNS Therapy system:
• Interrogate the VNS Therapy generator
• If the generator was reset during the scan, reprogram the serial
number, patient ID, and implant date, as needed
• Program the patient's therapeutic parameters as they were before the MRI
procedure
• Perform System Diagnostics. Results should indicate Impedance=OK
• Interrogate the generator again to confirm that reprogramming was
successful
* When an interrogation is performed by the programming software, the generator serial number,
implant date, stimulation parameters, and generator operating time are automatically logged in
the programmer database. This information may be retrieved from the database at any time after
interrogation.
† for select models with AutoStim mode
