DBS System Battery
Your St. Jude Medical Infinity™ DBS system has a component called an implantable pulse generator (IPG) that contains a battery. At each programming session, your doctor can check the status of your battery.
How long does the battery last?
How long the IPG battery lasts depends on how much therapy is required to manage your symptoms and the device’s settings. When your battery begins to run low, your doctor will recommend that you replace your IPG because the batteries are not removable from the system. There is warning before the battery runs low, so your doctor will advise when to schedule a replacement.
Replacing your IPG
When the battery begins to run low, your doctor will replace the IPG, and the procedure is usually shorter than the initial implant. This is because your doctor will leave the leads (wires) in place and connect them to your new IPG. Recovery time is often shorter than the initial system implant.
