Purpose of the device

The Medtronic Model 37751
Charging System is designed
to charge the Medtronic
Model 37711 Restore
Neurostimulator. The Restore

intended to provide electrical
stimulation to relieve severe,
intractable pain. Restore

Warnings

• DO NOT use the recharger on an
unhealed wound. The recharger, antenna,
and belt are not sterile, and contact with
the wound can cause an infection.

• Do not use the AC power supply near
water or during a lightning storm. Electric
shock, serious injury, or death may result.

Precautions

• Charge the neurostimulator when you see
a low battery ( ) screen on the patient
programmer or recharger; this prevents
the battery from overdischarging (see
glossary). If the neurostimulator battery is
allowed to overdischarge, charging is not
possible; however, the clinician may be
able to restore the battery function.
Allowing the neurostimulator battery to
overdischarge will permanently affect the
neurostimulator in one of the following
ways:

replaced. Battery function is not
restored because:

• The neurostimulator battery is
permanently damaged.

• The neurostimulator battery has
been overdischarged and restored
twice before. The third time the
battery is overdischarged, the
neurostimulator will reach end of
service. Surgery is required to
replace the neurostimulator.

• Do not expose the recharger or antenna
to extremely hot [eg, hot cars, saunas, or
direct sunlight; +40°C (104°F)] or cold
[eg, walk-in freezers; –20°C (–4°F)]
environments. The recharger and
antenna are sensitive to temperature
extremes and can become damaged.

recharger can damage your charging
system components.

• When operating a charging system, use
special care near flammable or explosive
atmospheres. An interaction between the
flammable or explosive atmospheres and
the battery in the device could occur. The
consequences of using a battery­powered device near flammable or
explosive atmospheres are unknown.

How to use this manual

This manual is designed to help you
understand your charging system. Ask your
clinician to explain anything that is unclear.

low, connect your recharger to the AC power
supply to conduct a charging session. The
power cord plugs into an electrical outlet and
connects the AC power supply to the
recharger. The power supply is a universal
component.

Note: Use only the power supply provided by
Medtronic with your charging system.

Antenna: The antenna connects to the
recharger to establish communication with
your neurostimulator. You can adjust a dial on
the antenna to improve the charging
efficiency between the recharger and the
neurostimulator.

Belt: The belt allows you to keep the antenna

directly over your neurostimulator during a

Pouch: The recharger fits into a pouch that
can be attached to the belt so you can
maintain your normal activities during a
charging session.

System carrying case: The carrying case is

How your charging system
works

The charging system is used to charge your
implanted neurostimulator battery. The
battery in your recharger is similar to the
rechargeable batteries commonly found in
electronic devices. The battery typically lasts
for approximately 5 years, depending upon
your therapy needs and how often you use
your recharger.

Rechargeable batteries lose some of their
power every day, even when not used.
Charging sessions restore power to the
recharger battery.

Caution:

• Charge the neurostimulator when you see

programmer or recharger; this prevents
