SAFETY INFORMATION
CONTRAINDICATIONS
•Poor surgical risks –Spinal cord stimulators should not be used on patients
who are poor surgical risks or patients with multiple illnesses or active
general infections. This includes patients who need anticoagulation
therapy that cannot be temporarily halted to accommodate the
implantation procedure.
•Pregnancy –Safety and effectiveness of the Freedom SCS System for use
during pregnancy and nursing have not been established.
•Inability to operate System –Spinal cord stimulators should not be used
on patients who are unable to understand or operate the System.
•Exposure to shortwave, microwave, or ultrasound diathermy –Diathermy
should not be operated within the vicinity of a patient implanted with a
Freedom Stimulator or when wearing the Wearable Antenna Assembly
(WAA). The energy from diathermy can be transferred through the
stimulator or WAA and cause tissue damage, resulting in severe injury.
•Implanted cardiac systems –Patients who have implanted cardiac systems
should not use the Freedom SCS System. Electrical pulses from the
Freedom SCS System may interact with the sensing operation of an
implanted cardiac system, causing the cardiac system to respond
inappropriately.
•Occupational exposure to high levels of non-ionizing radiation that may
interfere with therapy –Users who regularly work in environments with
elevated levels of non-ionizing radiation should not be implanted with the
Freedom SCS System. The energy in high-level areas can be transferred
through the stimulator and cause tissue damage, resulting in severe injury.
Examples of environments having high level non-ionizing radiation includes
radio or cell phone transmission stations, facilities using radiofrequency
heat sealers or induction heaters, electric power infrastructure controlled
environments (i.e. step down transformers or high voltage power lines).

WARNINGS
Electromagnetic interference (EMI) –EMI is a field of energy generated by
equipment found in the home, work, medical or public environments. EMI that
is very strong can interfere with System. The device includes features that
provide protection from EMI. Most electrical device and magnets encountered
in a normal day will not affect the operation of the System. However, strong
sources of EMI could result in the following:
•Serious patient injury resulting from heating of the implanted device
and damage to surrounding tissue.
•System damage, resulting in a loss of, or change in, symptom control
and requiring additional surgery.
•Operational changes to the WAA. This may cause either external
device to turn on, turn off, or to reset to factory settings. If this occurs,
the WAA need to be reprogrammed.
•Unexpected changes in stimulation, causing a momentary increase in
stimulation or intermittent stimulation. Some patients have described
as a jolting or shocking sensation. Although the unexpected change in
stimulation could feel uncomfortable, it does not damage the device
or cause a patient direct injury. In rare cases, as a result of the
unexpected changes in stimulation, patients have fallen down and
been injured.
If you suspect that your Freedom SCS System is being affected by EMI then you
should:
•Immediately move away from the equipment or object.
•Remove the WAA from the vicinity.
Machinery or heavy equipment –Machinery and heavy equipment (including
vehicles) should not be operated while using the Freedom SCS System.
Malfunction of the System could result in loss of body control, body function,
or a feeling that could render the patient incapable of controlling the system.
Stimulator fracture –If the Stimulator insulation is ruptured or pierced due to
extensive forces, unexpected changes in stimulation could result.
Electromagnetic equipment/environments –Avoidance of high
electromagnetic equipment radiators or environments is highly encouraged.
Examples of equipment and/or environments include the following:
•High-power amateur transmitters/antennas or citizen band (CB) radio
or Ham radio used for private recreation, communication, and wireless
experimentation.

English
Page | 7
•Electric arc welding or resistance welding equipment used for melting
and joining metals or plastics.
•Industrial electric induction furnace/heater or electric arc
furnace/heater used for melting metals and plastics.
•High-voltage areas identified by fenced areas, restricted access signs,
and caution signs (safe if outside the fenced area).
•Microwave transmitters identified by fenced areas, restricted access
signs, and caution signs (safe if outside the fenced area).
•Television and radio towers identified by fenced areas, restricted
access signs, and caution signs (safe if outside the fenced area).
•Linear power amplifiers used for increasing the power output of radio
transmitters, wireless communication applications, audio equipment
or other electronic equipment.
•Radio telemetry equipment used for tracking location of vehicles,
equipment or animals.
Active Implantable or Body Worn Medical Devices –Safety has not been
established for patients who use the Freedom SCS System with other active
implantable or body worn medical devices. These devices include other
neurostimulation systems, insulin pumps, automated external defibrillators
(AED), cochlear implants, and wearable medical sensors. Malfunction and/or
damage could occur to either system that could result in harm to the patient or
other people nearby.
Magnetic Resonance Imaging (MRI) –The Freedom-8A/4A SCS System is MR
Unsafe. Since the Freedom-8A/4A SCS System is MR Unsafe, the strong
magnetic field of the MR system could attract or otherwise damage the
System, and in the process cause serious harm to the patient or other people
or damage to the MR system.
The WAA component is MR Unsafe; ensure that the WAA does not enter the
MR system room. Since the WAA is MR Unsafe, the strong magnetic field of the
MR system could attract or otherwise damage the WAA, and in the process
cause serious harm to the patient or other people or damage the MR system.
Radiofrequency (RF) ablation –Safety has not been established for
radiofrequency (RF) ablation in patients with a Stimulator. RF ablation may
cause induced electrical currents that result in heating and tissue damage. Do
not use RF ablation anywhere near the Stimulator. If RF ablation is used, ensure
that ablation is not performed over or near the Stimulator.

English
Page | 8
Electrocautery –If electrocautery tools are used near the Stimulator then the
insulation can be damaged. The Stimulator may fail or conduct induced
currents. Induced electrical currents can cause heating that results in tissue
damage.
When electrocautery is necessary, these precautions must be followed:
•The WAA should be taken off.
•Bipolar cautery should be used.
•If unipolar cautery is necessary:
oOnly low-voltage modes should be used.
oThe lowest possible power setting should be used.
oThe current path (ground plate) should be kept as far away as
possible from the Stimulator.
oFull-length operating room table ground pads should not be used.
•After electrocautery, confirm that the Stimulator is working as
intended.
High-output ultrasonics / lithotripsy –Safety has not been established for
high-output ultrasonics or lithotripsy when implanted with the Freedom SCS
System. Use of lithotripsy may result in damage to the device or harm to the
patient.
Psychotherapeutic procedures –Safety has not been established for
psychotherapeutic procedures using equipment that generates
electromagnetic interference (e.g., electroconvulsive therapy, transcranial
magnetic stimulation) in patients who have spinal cord stimulators. Induced
electrical currents can cause heating that may result in tissue damage.
Radiofrequency Identification (RFID) Emitters - Theft detectors, electronic
article surveillance (EAS) systems, and radiofrequency identification systems
–Tests have been performed with an array of simulated RFID emitter systems,
and have demonstrated that the Freedom SCS System (implanted device and
WAA) can be affected by separation distances between the Freedom SCS
System and the RFID emitter of less than 3m (~10 ft.). More powerful RFID
Emitters might cause effect at farther distances. RFID emitters can be hidden or
portable and not obvious to the Stimwave user. Any RFID emitter may
temporarily interrupt stimulation, or cause elevated levels of stimulation. It is
recommended that if a patient feels a change in stimulation near a potential
RFID emitter, they promptly move away from the area and remove the WAA
from the body.

English
Page | 9
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:
oUsing the lowest possible X-ray tube current consistent with
obtaining the required image quality.
oMaking 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.

English
Page | 10
Laser procedures –Safety has not been established for lasers within the vicinity
of the Freedom SCS System. Use of lasers may result in damage to the device or
harm to the patient.
Radiation therapy –Safety has not been established for high radiation sources
such as cobalt 60 or gamma radiation when implanted with the Freedom SCS
System. Use of radiation therapy could cause damage to the device or harm to
the patient.
Transcutaneous electrical nerve stimulation –Safety has not been established
for use of transcutaneous electrical nerve stimulation (TENS) when implanted
with the Freedom SCS System. Use of TENS could cause the device to turn off
or intermittent/increased stimulation.
Other medical procedures –EMI from the following medical procedures is
unlikely to affect the device:
•Diagnostic ultrasound (e.g., carotid scan, Doppler studies)
•Diagnostic x-rays or fluoroscopy
•Magnetoencephalography (MEG)
•Positron emission tomography (PET) scans
•Therapeutic magnets (e.g., magnetic mattresses, blankets, wrist
wraps, elbow wraps) –Keep the magnet away from the stimulator
site. Magnetic fields will generally not affect the Stimulator.
WAA Skin Contact –Do not place the WAA directly on the skin. Direct skin
contact may cause irritation and/or sensitivity to the materials. The WAA must
be placed overtop a thin layer of clothing at all times.
Painful Stimulation –If the patient experiences painful stimulation, the
amplitude on the WAA should be decreased immediately and/or removed from
the patient’s body. Contact your clinician if this continues to occur.
Aircraft Usage –Safety has not been established for use of the Freedom SCS
System on aircrafts. Use of the Freedom SCS System on a commercial aircraft
may result in damage to the device or harm to the patient.

Medical tests and procedures –Before undergoing medical tests or
procedures, contact the clinician to determine if the procedure will cause
damage to the patient or to the System.
Physician instructions –Always follow the programs and therapy instructions
established by the clinician. Failure to do so may cause the therapy to be less
effective in providing pain relief.

English
Page | 12
Use the WAA as directed –Use the WAA only as explained by the clinician or as
discussed in the User Manual. Using the WAA in any other manner could result
in harm.
Do not dismantle the WAA–Do not dismantle or tamper with the device.
Tampering with the device could result in harm. If the device is not working
properly, contact the clinician for help.
Flammable or Explosive Environments –Do not use the WAA in flammable or
explosive environments. Using the WAA in one of these environments could
result in harm.
Use of another patient’s WAA - Never use another patient’s WAA. The therapy
programmed is a unique prescription for each patient. Use of another patient’s
WAA could result in overstimulation.
Activities requiring excessive twisting or stretching –Avoid activities that
potentially can put undue stress on the device. Activities that include sudden,
excessive, or repetitive bending, twisting, bouncing, or stretching can cause
your stimulator to fracture or migrate. This can result in a loss of stimulation,
intermittent stimulation, and additional medical procedures.
Scuba diving or hyperbaric chambers –Do not dive below 13 meters (45 feet)
of water or enter hyperbaric chambers above 1.5 atmospheres absolute (ATA).
These conditions can damage the device. Before diving or using a hyperbaric
chamber, discuss the effects of high pressure with the clinician.
Skydiving, skiing, or hiking in the mountains –High altitude should not affect
the System. However, take care to not put undue stress on the Stimulator.
During skydiving, the sudden jerking that occurs when the parachute opens can
dislodge or fracture the Stimulator. This can result in a loss of stimulation,
intermittent stimulation, and additional medical procedures.
Unexpected changes in stimulation –Electromagnetic interference, changes in
posture, and other activities can cause a perceived increase in stimulation.
Some patients have described this as a jolting or shocking sensation. You
should reduce your amplitude to the lowest setting and turn OFF your System
before engaging in activities that could become unsafe. Discuss these activities
with your clinician.

Interference during programming - If interference is suspected during
programming of the WAA, the clinician should confirm that the Bluetooth®
data transmission is operating properly. Bluetooth® data communication is
confirmed by the solid blue light on (when device is paired) and a fast blinking
yellow light (only when data is transmitted). If during the programming session
the light indicator is not blinking then the clinician should do the following:
•Terminate the current programming session and shut down the
WaveCrest Application.
•Check for sources of Bluetooth® interference in the surrounding area.
•Remove or turn off the source of interference.
•Re-establish the Bluetooth® link with the WAA through pairing.
•Resume programming by opening the WaveCrest Application.
•Confirm the light indicator is now blinking.

ADVERSE EVENT SUMMARY
Implantation of a spinal cord stimulation system is similar to any surgical
procedure. Risks include the following:
•Allergic or immune system response to implanted material
•Infection
•Leakage of cerebrospinal fluid
•Epidural hemorrhage, hematoma, or paralysis
Therapeutic use of the Freedom SCS System incurs the following risks:
•Undesired change in stimulation, including uncomfortable chest wall
stimulation
•Stimulator migration, erosion through the skin, or fracture causing a
loss of therapeutic effect
•Electromagnetic interference causing a change in System performance
•Loss of therapeutic effect despite a functioning system
Adverse events that could occur with the Freedom SCS System:
•Stimulator migration, resulting in altered stimulation therapy that may
be uncomfortable
•Stimulator fracture, resulting in loss of stimulation
•Infection, resulting in tissue sensitivity, redness and swelling
Adverse effects of stimulation are usually mild and go away when stimulation is
turned off. Contact your clinician immediately if you experience any problems.
Over time there could be changes in the level of pain control. Contact your
clinician if you experience a change in stimulation that you believe is a result of
the Stimulator slipping from the implant site.

PARTS OF YOUR STIMULATION SYSTEM
Freedom Stimulator –Also known as an “implant” or “receiver”. The
Stimulator is a set of thin wires and a miniature receiver, covered with a
protective casing. The Stimulator has small metal electrodes near the tip that
are set to different electrical polarities. An electrical field of energy is created
when power is applied to the electrodes. The electrical field aids in blocking the
pain signals coming from certain nerves near the spinal column. The Stimulator
receives energy wirelessly from the external unit (WAA).
Wearable Antenna Assembly (WAA) –The WAA is an electronic device used to
power the Stimulator. The device contains a rechargeable battery with an
antenna and micro USB port (for charging only). The WAA is worn near the area
where the Stimulator-Receiver is implanted.
The WAA communicates with your Stimulator-Receiver by sending
radiofrequency signals through the antenna. Your Stimulator-Receiver only
accepts communication from your WAA. The clinician programs your WAA with
your specific Stimulation parameters from a wireless Bluetooth® programming
tablet.
Antenna and Antenna Cable –The antenna sends out the wireless signal. The
antenna is permanently attached to the antenna cable. The antenna is
permanently connected to the Microwave Field Stimulator (MFS) with the
antenna cable.
