Convention What it means

Note

Note: A note provides helpful information.

Caution

Caution: A caution notifies you of a potential
hazard which, if not avoided, may result in minor
or moderate injury or damage to the equipment.

WARNING

WARNING: A warning notifies you of a
potential hazard which, if not avoided, could
result in death or serious injury. It may also
describe potential serious adverse reactions and
safety hazards.

Emergency kit

Keep an emergency kit with you at all times to make sure that you always have
necessary supplies. Tell a family member, co-worker, or friend where you keep your
emergency kit.

It is important that you test your blood glucose (BG) more frequently while you are
traveling. The routine hassle of travel, including stress, changes in time zones,
schedules and activity levels, meal times and types of food, can all affect your
diabetes control. Be extra attentive to monitoring your BG frequently, and be
prepared to respond if needed.

Your emergency kit should include these items:

• Fast-acting glucose tablets.

• Blood glucose monitoring supplies.

• Urine or blood ketone monitoring supplies.

• Extra MiniMed-compatible infusion set and MiniMed reservoir.

• Extra new AA lithium or alkaline batteries, or fully charged NiMH batteries.

4 Chapter 1

MP6025957-024 / A

RELEASED

• Insulin syringe and fast-acting insulin (with dosage instructions from your
healthcare professional).

• Wallet card (packaged with your pump accessories).

• Adhesive dressing.

• Glucagon emergency kit.

WARNING: Do not use the Bolus Wizard™ to calculate a bolus for a
period of time after giving a manual injection of insulin by syringe
or pen. Manual injections are not accounted for in the active insulin
amount. Therefore, the Bolus Wizard could prompt you to deliver
more insulin than needed. Too much insulin may cause
hypoglycemia. Consult with your healthcare professional for how
long you need to wait after a manual injection of insulin before you
can rely on the active insulin calculation of your Bolus Wizard.

For details on pump safety, see User safety, on page 5.

User safety

Indications

MiniMed 640G system

The MiniMed 640G system is indicated for the continuous delivery of insulin, at set
and variable rates, for the management of diabetes mellitus in persons requiring
insulin. In addition, the system is indicated for continuous or periodic monitoring
of glucose levels in the fluid under the skin, and detecting possible low and high
glucose episodes. When using a sensor and transmitter, the pump displays
continuous sensor glucose values and stores this data so that it can be analyzed to
track patterns and improve diabetes management. This data can be uploaded to a
computer for analysis of historical glucose values.

The continuous sensor glucose values provided by the MiniMed 640G system are
not intended to be used directly for making therapy adjustments. Rather, they
provide an indication that a confirmation fingerstick measurement may be
required. All therapy adjustments should be based on measurements obtained
using a home blood glucose monitor and not based on the value displayed by the
pump.

Contraindications

Pump therapy is not recommended for people who are unwilling or unable to
perform a minimum of four blood glucose tests per day.

Pump therapy is not recommended for people who are unwilling or unable to
maintain contact with their healthcare professional.

Pump therapy is not recommended for people whose vision or hearing does not
allow recognition of pump signals and alarms.

General warnings

Pump

The pump is not suitable for use in the presence of a flammable anesthetic
mixture with air, oxygen, or nitrous oxide.

Never rely on the pump beeps or vibrations alone to navigate through the pump
screens or menus because this may result in incorrect menu selection or setting.

Do not rely on preset pump alarms or reminders alone to prompt you to check
your blood glucose. Set additional reminders on other devices, such as your cell
phone, to avoid forgetting to check your blood glucose.

Standard Luer sets are not compatible with the MiniMed 640G insulin pump.
MiniMed reservoirs and MiniMed-compatible infusion sets are specifically designed
for use with the MiniMed 640G insulin pump. Do not modify your MiniMed
reservoir or MiniMed-compatible infusion set.

Only use U100 insulin that has been prescribed by your healthcare professional for
use with an infusion pump. Do not put any other drugs or medications inside your
reservoir for use with this pump.

Make sure the infusion set is disconnected from your body before you rewind your
pump or fill the infusion set tubing. Never insert the reservoir into the pump while
the tubing is connected to your body. Doing so could result in an accidental
infusion of insulin.

Do not insert the reservoir in the pump if you did not rewind your pump. Doing
so could result in an accidental infusion of insulin.

While the infusion set is connected to your body, do not unscrew or retighten the
tubing connector on the reservoir.

6 Chapter 1

MP6025957-024 / A

RELEASED

Do not use the MiniLink™ transmitter (MMT-7703) with the MiniMed 640G insulin
pump as this device does not communicate with this insulin pump.

Do not modify this product, as modification could result in a safety hazard.

Do not use your pump if the screen appears broken or unreadable. In some
instances, impact to the pump can damage the screen while the buttons continue
to function. If the screen is broken or unreadable, do not press any buttons.
Remove the pump and begin using your backup insulin plan per the direction of
your healthcare professional. If the pump is accidentally programmed while the
screen is broken or unreadable, this could result in high or low blood glucose
levels. If your screen is damaged, contact the 24 Hour HelpLine or your local
representative to arrange for shipment of a replacement pump.

Exposure to magnetic fields and radiation

WARNING: Keep the pump away from magnetic fields and avoid
direct contact with any magnets.

If you are going to have an X-ray, MRI, diathermy treatment, CT scan, or other type
of exposure to radiation, take off your pump, sensor, transmitter, and meter before
entering a room containing any equipment of this kind. The magnetic fields and
radiation in the immediate vicinity of this equipment can make your devices
nonfunctional or damage the part of the pump that regulates insulin delivery,
possibly resulting in over delivery and severe hypoglycemia.

Do not expose your pump to a permanent magnet, such as pump cases that have
a magnetic clasp. Exposure to a permanent magnet may interfere with the motor
inside the pump.

Reservoir and infusion sets

Only use reservoir and infusion sets manufactured by Medtronic Diabetes. The
pump has undergone extensive testing to confirm appropriate operation when
used with compatible reservoirs and infusion sets manufactured or distributed by
Medtronic Diabetes. We cannot guarantee appropriate operation if the pump is
used with reservoirs or infusion sets offered by third parties. We are not
responsible for any injury or malfunctioning of the pump that may occur in
association with such use.

MP6025957-024 / A

RELEASED

Only use U100 insulin that has been prescribed by your healthcare professional for
use with an infusion pump. Do not put any other drugs or medications inside your
reservoir for use with this pump.

For additional warnings related to the reservoir and infusion set, refer to the user
guides provided with those devices.

Sensor

While there is no evidence of an Enlite™ sensor breaking in a patient’s body, if you
suspect that sensor breakage has occurred, do not attempt to remove the sensor
yourself. Contact your healthcare professional for assistance in removing the
sensor.

For warnings related to the sensor, refer to the user guide provided with that
device.

Transmitter

Keep the transmitter away from children. This product contains small parts and
may pose a choking hazard.

For warnings related to the transmitter, refer to the user guide provided with that
device.

Meter

For warnings related to compatible Bayer™ meters, refer to the user guide
provided with that device.

General precautions

Although the pump has multiple safety alarms, it cannot notify you if the infusion
set is leaking or the insulin has lost its potency. It is essential, that you test your
blood glucose levels at least four times per day. If your blood glucose is out of
range, check the pump and the infusion set to ensure that the necessary amount
of insulin is being delivered.

Waterproof capabilities

At the time of manufacture and when the reservoir and tubing are properly
inserted, your pump is waterproof. It is protected against the effects of being
underwater to a depth of up to 3.6 meters (12 feet) for up to 24 hours.

8 Chapter 1

MP6025957-024 / A

RELEASED

If the pump is dropped, hit against a hard object, or otherwise damaged, the
waterproof characteristics of the outer casing of the pump may be compromised.
If your pump has been dropped or you suspect your pump is damaged, carefully
inspect your pump to ensure there are no cracks before exposing your pump to
water.

If you believe that water has entered your pump or you observe any other
possible pump malfunction, check your blood glucose, and treat high blood
glucose as necessary, using an alternative source of insulin. Contact your local
representative for further assistance. Always contact your healthcare professional if
you experience excessively high or low blood glucose levels or if you have any
questions about your care.

Electrostatic discharge

Although your MiniMed 640G insulin pump is designed to be unaffected by typical
levels of electrostatic discharge (ESD), very high levels of ESD can result in a reset
of the pump's software and a pump error alarm. After clearing the alarm, verify
that your pump is set to the correct date and time and that all other settings are
programmed to the desired values because the software reset could erase your
previously programmed settings.

For more information on pump alarms, see Pump alarms, alerts, and messages, on

page 202. For more information on re-entering your pump settings, see My pump
is asking me to enter my settings, on page 232. If you are unable to re-enter your

pump settings, or otherwise believe there is a problem with your pump, contact
your local representative.

Avoid extreme temperatures

Exposure to extreme temperatures can damage your device, which can adversely
affect safety and effectiveness of your device. Avoid the following conditions:

1. Avoid exposing your pump to temperatures above 40 °C (104 °F) or below

5 °C (41 °F) because this may damage your device.

2. Insulin solutions freeze near 0 °C (32 °F) and degrade at high temperatures. If

you are outside in cold weather, wear your pump close to your body and
cover it with warm clothing. If you are in a warm environment, take measures
to keep your pump and insulin cool.
