Overview – Power Module
The new GoGear System Components are designed to support a patient’s active
lifestyle, providing mobility and flexibility in a safe, secure manner.
• Flexible Power Source – The Power Module is a portable solution that powers the
HeartMate system safely and securely.
– One-third the weight of the Power Base Unit (PBU)
– Integrated backup battery provides emergency support for up to 30 minutes
– Simple, effective light indicators and audio alarms give immediate feedback on
system operation
– Automobile port offers patients the added convenience of “plugging in” while in the
car
– Powers the System Monitor and Display Module for system programming and
monitoring purposes

Overview – Universal Battery Charger
• Mobile Charging Capacity – The Universal Battery Charger is compact and lightweight
with rapid charging technology to complement an on-the-go lifestyle.
– Weighs only eight pounds – highly portable
– Rapid charging minimizes the number of batteries required for excursions –
reduces the burden of battery management
– Continuous diagnostic testing and automatic calibration delivers consistent battery
performance
– Intuitive light indicators provide readily-accessible battery status
44
Overview – Batteries / Clips
• Advanced Battery Technology – Light, long-lasting and smart – batteries have been
developed specifically for HeartMate patients’ active lifestyles.
– Weighs only one pound (14V Li-Ion batteries)
– Provides a full work day of support on a single charge (up to 10 hours)
– Smart technology affords optimal charging, accurately gauges charge level and
ensures battery lifespan (up to three years)

Overview – Smart HM II Controller
A new, upgraded HM II system controller is required to operate GoGear System
Components.
• The upgraded controller has embedded advanced “smart” technology.
– These smart controllers have the ability to communicate with the new HeartMate
batteries providing accurate fuel gauging during discharge.
• Old HM II controllers are not compatible with 14 V Li-ion batteries and clips.
– Physical “lock-outs” prevent old HM II controllers from being used with 14V Li-ion
battery clips.
• Smart controllers may be used with old batteries and clips.
• Smart controllers can be identified by new catalog #103696, white strain reliefs, white
belt clip and software label: V. 4.12.

Power Module – Overview
The Power Module (PM) performs four primary functions:
1. Provides electrical power to the LVAS during tethered operation, by
connecting to an AC power source
2. Provides electrical power to the Display Module or System Monitor when
either device is connected to the PM and the PM is plugged into AC power
3. Connects the Display Module / System Monitor to the System Controller for
monitoring purposes
4. Echoes System Controller alarms
Four components are required for tethered operation with the PM: 1) the PM
itself, 2) a PM patient cable, 3) a PM power cord, and 4) a HeartMate II or XVE
