CHARGING EXPERIENCE

The 37651 charging system

The Medtronic 37651 DBS charging system guarantees patient comfort and safety during the charging experience thanks to:

■ Temperature control during recharging

The system constantly monitors the temperature and the antenna connection.

If the temperature rises above a certain level:

- The system displays a warning message

- The charging power is reduced until the antenna cools down

■ Temperature control function

- Monitors the antenna temperature every minute

- Automatically shuts o when the temperature rises above 38.3°C

- Charging restarts automatically when the temperature returns to a safe level.

■ Adhesive disc to improve the attachment of the antenna during charging (Ref.: 040618)

1 3 42

These double-sided adhesive discs provide better attachment of the antenna during charging, keeping the head of the antenna from moving unintentionally and thus improving the charging

time. It is recommended not to place the adhesive directly on the skin.

■ Long-term battery performance

The proven

long-term performance of the battery used in Activa™ RC neurostimulators shows

that patients will experience a similar charging time and frequency over the entire service life of the device.

Note: It is possible

to charge the neurostimulator battery and the charger battery

at the same time.

Checking the battery status

Both the neurostimulator and the charger need to be charged.

Charge the charger battery

1. Connect the charger cable (AC power supply) to an AC outlet. The green light on the power supply indicates that it is live.

2. Connect the AC power supply. The charger will begin to be charged when it is connected to the AC power supply, and the charging session screen will be displayed on the charger.

You can check the neurostimulator by positioning the patient programmer over the

implant or by using the programmer’s antenna.

1. Place the programmer or the antenna

over the neurostimulator and press the

CHECK KEY

Note: Pressing the CHECK KEY

2. The Therapy screen shows the neurostimulator battery status.

Charge Needed

It is very important that you check the neurostimulator battery every day.

Note: If your physician has enabled the Alert

before the alarm time each day, an alarm will

sound to remind you that you must check the

Placing the shoulder strap and adjusting the antenna

1. Remove the shoulder strap from the packaging. Pass the left end of the

shoulder strap through

the white fastener.

2. Press the skin in the area where the neurostimulator is located. In this example, the

patient has the neurostimulator implanted on

the left side.

3. Put the shoulder strap on the left shoulder. Place the antenna in

the opening and secure it in position using the

adhesive strip.

4. Secure the buckle and tighten the shoulder strap. Adjust the belt so that the antenna is centred over the neurostimulator.

Note: For more information about an implant

located on the right side, see the instructions

for use on the RC antenna case.

Charge the neurostimulator battery

1. Place the belt or shoulder strap over the neurostimulator.

2. Place and secure the antenna in position.

3. Press the green START CHARGE/TEST button on the charger.

4. The charger display will show the Charger

Waiting screen, which indicates that the

neurostimulator and the charger are trying

to communicate.

Charger Waiting screen

Note: After placing the charger over the

neurostimulator, wait for at least 10 seconds to check for maximum eciency.

5. When charging begins, the Neurostimulator

Charging screen will appear. This screen:

■ Conrms the status and progress of

the neurostimulator charging session.

■ Shows you the status of the charger

battery.

■ Shows a blinking battery icon for the

neurostimulator, which indicates that the battery is recharging.
