The HeartMate II system
HeartMate II is an LVAD
that assists the heart in pumping oxygen-rich blood throughout the body, so the
organs and muscles can function properly. The HeartMate II system includes
parts that exist inside and outside the body.

- During routine use, the heart pump is powered by 1 of 2 power sources—batteries
or the power module
- The rechargeable batteries are light, weighing only 1 pound, and
they last a long time. A pair of wearable batteries provides 10 to 12 hours
of uninterrupted support, nearly twice as long as other devices. A battery charger
keeps your spare batteries ready to go whenever you are
- A power module is also provided which plugs into an electrical
outlet. It is designed to be used when you’re at rest, asleep, or when you’re in
the car on long trips
- A thin cable (called the driveline) goes through your abdomen.
It connects the Pocket Controller to the heart pump
- The driveline sends power and operating signals to the heart pump
- The device is placed just below the diaphragm in the abdomen. One end of the heart
pump connects to the left ventricle (the heart’s main pumping chamber).
The other end connects to the aorta (the large blood vessel that
sends blood through the body)
- The heart pump does not replace the heart. It assists the heart in sending oxygen-rich
blood to the rest of the body
- The easy-to-wear Pocket Controller weighs only 1 pound and can
discreetly slip into a front pocket. You can be confident knowing it includes 15
minutes of emergency backup power
- The Pocket Controller uses alerts to tell you how the system is working
“The equipment is a part of me, but it's not noticeable. It's not a burden,
even with the little extra weight. You know it's what's keeping you alive. It's
really NOT a big deal!”
