HeartMate III Left Ventricular Assist System Instructions for Use
System Controller Backup Battery Power
An 11 Volt Lithium-Ion backup battery is installed post-implant inside the System Controller.
It provides at least 15 minutes of backup power to the LVAD if the in-use power source is
disconnected or fails. To provide backup power, the 11 Volt Lithium-Ion backup battery must be
properly installed and fully charged.
The 11 Volt Lithium-Ion backup battery is intended only for backup power during a power
emergency. Emphasize to patients that inappropriate use during non-emergencies may reduce the
power available to them in a true emergency. Backup battery use is automatically recorded by the
System Controller. This allows for follow-up training with patients, if needed, to reinforce that
usage should be limited to power emergencies. Refer to
4-43 for instructions on accessing 11 Volt Lithium-Ion backup battery usage records.
After proper installation, the rechargeable 11 Volt Lithium-Ion backup battery recharges
automatically any time the running System Controller is connected to a power source. It takes up
to three hours to charge a fully-depleted 11 Volt Lithium-Ion backup battery. Although
rechargeable, the backup battery has a limited lifespan. The lifespan of a backup battery is
36 months from manufacture date. Therefore, it may be necessary to install a replacement backup
battery if the current one expires, or if prompted by a Backup Battery Fault alarm.
Figure 2.23 Backup Battery Fault Alarm
The backup System Controller also has an 11 Volt Lithium-Ion backup battery. The sleeping
backup System Controller must be connected to power (put into Charge Mode) at least every
six months to charge the backup battery inside the backup System Controller. Refer to
Backup System Controller Readiness
WARNING !
The 11 Volt Lithium-Ion back up battery inside the System Controller will not by itself start a
HeartMate III LVAD if both of the System Controller's power cables are disconnected from
a power source. Always ensure that the power cables are connected to a power source to
ensure that the HeartMate III Pump will restart during a System Controller exchange.
