What provides power to left ventricular assist devices (LVADs)?

Power to left ventricular assist devices (LVADs) is provided by batteries. The batteries are external and people normally have some sort of pack that they wear around their abdomen which contains the batteries. The batteries are connected to the device by a drive line, which goes through a small incision on the side of the abdomen.

People normally are given multiple packs of batteries and are educated in terms of the importance of how long the batteries last, how often they need to be recharged, and the importance of having fully charged batteries at all times. The batteries last for quite a long time, so people are able to go out without concerns of having to constantly change the batteries.

However, if they're going out for an extended period of time they may want to take extra batteries just to be on the safe side.
