When possible, it is best to avoid RFID emitters or remove the WAA while
passing near RFID emitters. Patients with an implanted device should inform
the attendant who may be able to assist them in bypassing any RFID emitter. If
unavoidable, the patient should walk through the RFID emitter and promptly
move away from the area. Patients should not lean on scanners or linger in the
area of RFID emitters.
Computed Tomography (CT) Scanning
–
Safety has not been established for CT
scanning of patients with a Stimulator. X-rays from the scan could cause
unintended shocks or malfunctions of the Stimulator.
The CT operator should use CT scout views to determine if implanted medical
devices are present and their location relative to the programmed scan range.
For CT procedures in which the device is in or immediately adjacent to the
programmed scan range, the operator should:
•
Remove the WAA from the CT scan range.
•
Minimize X-ray exposure to the implanted device by:
o
Using the lowest possible X-ray tube current consistent with
obtaining the required image quality.
o
Making sure that the X-ray beam does not dwell over the
Stimulator for more than a few seconds.
After CT scanning directly over the implanted device:
•
Place the WAA on body and turn on stimulation.
•
Check for proper stimulation, and that indicator lights are operating as
expected.
•
Shut off the WAA if it is suspected that the device is not functioning
properly.
Bone growth stimulators
–
Safety has not been established for bone growth
stimulators within the vicinity of the Freedom SCS System. Use of a bone
growth stimulator may result in damage to the device or harm to the patient.
Dental drills and ultrasonic probes
–
Safety has not been established for dental
drills or ultrasonic probes within the vicinity of the Freedom SCS System. Use of
dental drills or ultrasonic probes may result in damage to the device or harm to
the patient.
Electrolysis
–
Safety has not been established for electrolysis within the vicinity
of the Freedom SCS System. Use of electrolysis may result in damage to the
device or harm to the patient.
