Using HeartMate 14 Volt Lithium-Ion Batteries
Using battery power for the HeartMate III LVAS allows for greater patient mobility than when the
patient is connected to the Power Module or Mobile Power Unit. When using battery power, a
patient can enjoy activities outdoors or away from home, such as gardening or shopping.
A pair of HeartMate 14 Volt Lithium-Ion batteries ( Figure 3.57 ) provides direct current (DC) to
the Pump. Both batteries are discharged together (not one, then the other).
Figure 3.57 HeartMate 14 Volt Lithium-Ion Battery
Each battery is inserted into a 14 Volt battery clip ( Figure 3.58 ). The batteries and attached
battery clips can be worn in holsters (one under each arm), or across the body (in a bag), or in a
pouch around the waist. The battery clips transfer power from the batteries to the
System Controller. Using battery clips is required with the batteries.
