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.

Basal

Basal insulin is the "background" insulin that you need throughout the day and
night to maintain your target blood glucose values when you are not eating. Your
basal insulin accounts for approximately one half of your daily insulin requirements.
Your pump mimics a pancreas by delivering insulin continuously over 24 hours.

Your basal insulin is delivered according to a basal pattern. Basal patterns and
other basal settings are described in the following sections.

Basal rate

Your basal rate is the specific amount of basal insulin that your pump continuously
delivers each hour. While some people use one basal rate all day, others require
different rates at different times of the day.

Your basal rates are set in one or more basal patterns. Each basal pattern covers
24 hours. For specific information about basal patterns, see Basal patterns, on
page 41.

Basal insulin settings

Your basal insulin delivery settings are described in the following table.

Setting What it is What it does for you

Basal Pattern A set of one or more

basal rates that cover a
24-hour period.

Determines the amount of insulin you
receive per hour throughout the day
and night. Allows you to vary your basal
rate according to your needs. You can
set up to eight basal patterns. For
details on setting up basal patterns, see
Adding a new basal pattern, on page 42.
For details about starting a basal
pattern, see Changing from one basal
pattern to another, on page 46.

Temp Basal A basal rate that you use

in place of your
scheduled basal rate for
short-term situations.

Allows you to temporarily change your
current basal rate for a duration of time
that you specify. For details about
starting a temp basal rate, see Starting a
Temp Basal rate, on page 48.

Preset Temp A temporary basal rate

that you can define
ahead of time.

Allows you to set and save temporary
basal rates for known short-term
situations, such as when you are sick or
have times of increased or decreased
activity. For details about setting up a
preset temp basal rate, see Preset Temp
basal rates, on page 49. For details
about starting a preset temp basal rate,
see Starting a Preset Temp basal rate, on
page 51.

Max Basal Rate Maximum amount of

basal insulin that your
pump can deliver
per hour.

Provides a safety measure by limiting
the total amount of basal insulin your
pump can deliver per hour. For details
about setting your Max Basal rate, see
Max Basal Rate, on page 41.

Max Basal Rate

Max Basal Rate limits the amount of basal insulin that can be delivered per hour,
based on the maximum rate you set. You are unable to set any basal rates, temp
basal rates, or preset temp basal rates that exceed the max basal rate amount. You
can set your max basal rate from 0 to 35 units per hour. Set your max basal rate as
prescribed by your healthcare professional.

Note: If you are setting your max basal rate after you have set up your
basal patterns or preset temp basal rates, you cannot set your max basal
rate lower than any of your existing basal rates. You cannot access this
feature during a bolus delivery.

Basal patterns

Your basal pattern determines the amount of basal insulin you receive throughout
the day and night. Because your basal insulin needs can vary, you can set up to
eight basal patterns. For example, you might use one basal pattern during the
week and a different basal pattern during the weekend.

A basal pattern is made up of one to 48 basal rates that you set up to cover a full
24-hour period. If you only need one basal rate throughout the day, you set only
one rate for the 24-hour period. If you need the basal rates to change during the
day or night to better match your insulin needs, you can set more than one rate,
each with a separate start and end time.

The following example represents one basal pattern with three basal rates set for
three different time periods.

Temporary basal rates

The Temp Basal feature and Preset Temp feature allow you to set temporary basal
rates to manage blood glucose levels during short-term activities or conditions
that require a basal rate different than your current one, such as an illness or a
change in physical activity. You can make an immediate change to your basal
insulin for a set period of time (30 minutes to 24 hours), up to your max basal rate.

About Temp Basal rates

A temp basal rate temporarily overrides all other basal programming. Your
programmed basal pattern resumes after the temp basal rate delivery is completed
or cancelled.

The Temp Basal feature allows you to set and start a temporary basal rate
immediately. The Preset Temp feature allows you to set up a temp basal rate
ahead of time for known situations. You define temp basal rates and preset temp
basal rates using either a percentage of your current basal pattern, or by setting a
specific rate, as described in the following table.

This temp basal type: Works like this:

Percent Delivers a percentage of the basal rates programmed

in your active basal pattern for the duration of the
temp basal rate. The temp basal amount is rounded
down to the next 0.025 units if your basal rate is set at
less than 1 unit per hour, or to the next 0.05 units if
your basal rate is set at more than 1 unit per hour.

Temp basal rates can be set to deliver from 0 to 200%
of your scheduled basal rate. The percent amount you
can use, however, is based on the largest basal rate
scheduled during the temp basal duration, and is
limited by your max basal rate.

Rate Delivers a fixed basal insulin rate in units per hour for

the duration of your temporary basal, limited by your
max basal rate.

To use the Temp Basal feature, see Starting a Temp Basal rate, on page 48. To use
the Preset Temp Basal feature, see Preset Temp basal rates, on page 49.

Stopping and resuming your insulin delivery

Use Suspend Delivery if you need to stop all active basal and bolus insulin
deliveries. When you suspend your insulin delivery, your pump beeps and vibrates
every 15 minutes to remind you that insulin is not being delivered.

When you are ready to continue your basal insulin delivery, use the Resume
feature. When you use the Resume feature, your pump starts your programmed
basal pattern, but does not start any previously programmed bolus deliveries.

Note: If you want to stop a bolus delivery only, without stopping your
basal delivery, see Stopping a bolus delivery, on page 88.

WARNING: A bolus delivery or fill cannula that was suspended
does not restart when you resume. To avoid a high BG and
ketoacidosis, always check the pump's Daily History after you
resume insulin delivery to determine the amount that was
delivered. If needed, program a new bolus or fill cannula delivery.

Caution: When using Audio or Vibrate, it is possible that an Audio or
Vibration notification may not occur as expected if the speaker or
vibrator in your pump malfunctions. This is most important when
using the Easy Bolus feature or when your pump is in Manual Suspend
where a missed notification may cause an over or under delivery of
insulin.

Contact the 24 Hour HelpLine or your local representative with any
concerns.

To suspend all insulin delivery:

1. Go to the Suspend Delivery screen.

Menu > Suspend Delivery

2. A confirmation message appears. To suspend your pump and stop all insulin

delivery, select Yes.

The Home screen indicates that your insulin is suspended. Your pump
functions are limited until you resume your insulin delivery.

To resume basal insulin delivery:

1. While insulin is suspended, go to the Home screen.

2. Select Resume.

A confirmation message appears.

3. To resume your basal insulin delivery, select Yes. If a Temp Basal was active

when you suspended your pump, it resumes if the time is still within the
duration that you set.

Note: If you still need a bolus delivery that was in progress before
you suspended your delivery, check the Daily History screen for the
actual bolus units delivered and the intended bolus amount. Then
you can set up a new bolus amount as needed. See Daily History, on
page 121 for details about using the Daily History screen.

Bolus

A bolus is the amount of insulin taken to cover an expected rise in blood glucose,
typically when you eat a meal or snack. You can also use a bolus to correct a high
blood glucose reading.

About bolus deliveries

There are different types of bolus deliveries you can use, depending on your
insulin needs at the time. There are also different ways you can deliver a bolus.
Discuss these options with your healthcare professional to determine what is best
for you.

Bolus types

The following table provides general information about the available bolus types.

Type How it works When to use it

Normal Provides a single

immediate dose of
insulin.

This is the typical bolus type you use to
cover your food intake, or to correct a high
BG meter reading.

For details about using the Normal bolus
feature, see Normal bolus, on page 73.

Bolus Wizard

The Bolus Wizard is a feature that uses your individual Bolus Wizard settings to
calculate an estimated bolus amount based on the BG values and carbs that you
enter. Work with your healthcare professional to define your personal settings,
which include your carb or exchange ratio, insulin sensitivity, BG target range, and
active insulin time.

Note: If you do not know how to count carbs, consult with your
healthcare professional before using the Bolus Wizard.

After you set up the Bolus Wizard, you can use it to calculate and deliver a food
bolus, a correction bolus, or a food plus correction bolus using a Normal bolus (see
page 74), Square Wave bolus (see page 77), or Dual Wave bolus (see page 80).

Always remember these two things when you are using the Bolus Wizard:

• Never give a bolus that was calculated more than 12 minutes ago. That bolus

amount was based on a BG value that is no longer current. Instead, take a
new BG meter test and have the Bolus Wizard re-calculate the necessary bolus
amount.

• When using the Bolus Wizard, promptly respond to any message displayed on

the pump screen. Your prompt response is needed to complete the task.

The following sections describe how to set up the Bolus Wizard. Bolus delivery
instructions are provided in the individual sections for each bolus type.

Understanding your Bolus Wizard settings

Your pump guides you through entering the following settings when you first turn
on the Bolus Wizard feature. Get your prescribed settings from your healthcare
professional, and always consult your healthcare professional before changing your
settings. The setup procedure begins on page 66.

Setting What it does

Carb Ratio
Exchange Ratio

Used for food bolus calculations.

• If you count carbs: the number of carb grams that are
covered by 1 unit of insulin.

• If you count exchanges: the number of insulin units that
are needed to cover 1 carb exchange.

Insulin Sensitivity
Factor

Used to calculate correction bolus amounts.

Your insulin sensitivity factor is the amount that blood
glucose is reduced by one unit of insulin.

BG Target The Bolus Wizard calculates your estimated bolus based

on your BG target range. The high and low values you set
are the values to which your blood glucose is corrected.
To use a single target value rather than a range, set the
same value for High and Low.

If your BG value is above the high target value, a
correction dose is calculated. If your BG value is below
the low target value, a negative correction is calculated
and subtracted from your food bolus.

Active Insulin Time Active insulin is the bolus insulin that has been delivered

by the pump and is still working to lower your blood
glucose levels. Active insulin time is the length of time
that bolus insulin is tracked as active insulin.

Work with your healthcare professional to get the active
insulin time that best represents the insulin type you use
and your physiological insulin absorption rate.

For more information about how the Bolus Wizard uses
your active insulin amount, see About active insulin, on
page 72.

About active insulin

Active insulin is the bolus insulin that has already been delivered to your body,
and is still working to lower your blood glucose levels. The pump considers your
active insulin time setting in determining if any active insulin is still in your body
from prior boluses. This may help prevent hypoglycemia caused by over-correcting
for high blood glucose.

Your current active insulin amount displays on the Home screen, and includes only
the bolus insulin you have already received.

When you are using the Bolus Wizard, the Bolus Wizard calculator uses your
current active insulin value to determine if there is an active insulin adjustment
needed. The active insulin adjustment calculation considers both the bolus insulin
that has already been delivered (the amount shown on the Home screen), as well
as any insulin that is going to be delivered by an active Square Wave bolus.

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.

Bolus Wizard warnings

When you use the Bolus Wizard, there may be times when you see one of the
following:

Warning: What it means: What to do:

High BG Your BG meter reading is above

13.9 mmol/L.

• Check for an occlusion.

• Check ketones.

• Consider an insulin injection.

• Monitor your BG.

72 Chapter 4

MP6025957-024 / A

RELEASED

Warning: What it means: What to do:

Low BG Your BG meter reading is below

3.9 mmol/L.

Treat your low BG. Do not give
yourself a bolus until your BG
returns to normal.

Max Bolus
Exceeded

The bolus amount entered
exceeds your Max Bolus setting.

Check the bolus amount. Select
No to cancel, or Yes to
continue. If you select Yes, the
bolus amount that you entered
is reduced to your max bolus
limit.

Let your healthcare professional
know if you routinely receive
the Max Bolus exceeded
warning so that they can adjust
your pump settings.

Note: In the event that you do not clear the High BG, Low BG, or Max
Bolus exceeded warning, the warning will remain on your pump
indefinitely. If you clear the message after more than 12 minutes have
passed, do not deliver the bolus amount shown. That bolus amount was
based on a BG value that is no longer current. Instead, return to the
Home screen and check your BG again with your meter. Enter the new
value into the Bolus Wizard and give a bolus if needed.

Normal bolus

A Normal bolus provides a single immediate dose of insulin. You use a Normal
bolus to cover your food intake or to correct a high BG meter reading.

You cannot access the Reservoir & Tubing, Insulin Settings, or Sensor Settings
menu options during a Normal bolus delivery.

Note: Your pump allows you to deliver a Normal bolus while a Square
Wave bolus or the Square portion of a Dual Wave bolus is being
delivered.

Easy Bolus

The Easy Bolus feature allows you to quickly deliver a Normal bolus using only the

button. Your pump must be in sleep mode to use the Easy Bolus feature.

Before using Easy Bolus, you must turn on the feature and set the step size. The
step size determines the number of units the bolus amount increases each time
you press the

button. Your Easy Bolus delivery is limited to 20 steps or your max

bolus limit, whichever comes first.

To help you count your Easy Bolus steps, each time you press the button, your
pump makes a different tone. There are five different tones that repeat if you use
more than five steps.

Understanding Easy Bolus step sizes

When setting up Easy Bolus, you can set the step size from 0.1 to 2.0 units. Your
step size cannot be higher than your max bolus. Set the step size to a number
that is convenient to use and easy to multiply.

The following example shows how your bolus amount is increased with each step,
or each press of the

button when using the Easy Bolus feature to deliver a
bolus. In this example, the step size is 0.5 units. For a delivery of 2.0 units, you
would need four steps, or press the button four times when using the Easy
Bolus feature.
