Secondary power sources for implantable medical devices must satisfy the same general requirements as primary batteries, including safety, reliability, high energy density, and low self-discharge. Neurostimulators, which operate in the milliwatt power range, are one type of device for which secondary batteries have been developed.
Some applications having high power usage rates can benefit from the use of rechargeable batteries in order to improve implant lifetime and reduce size. Secondary power sources for implantable medical devices must satisfy the same general requirements as primary batteries, including safety, reliability, high energy density, and low self-discharge.
1. Introduction Batteries developed for implantable biomedical devices have helped enable the successful deployment of the devices and their treatment of human disease. The medical devices are permanently implanted to continually monitor a patient and provide therapy on a predetermined schedule or as needed.
Medical device batteries serve an important role in modern health care. They power the devices that allow patients to function more normally by managing and improving their health or even survive life threatening disease conditions. There are several ways to classify medical devices.
Pairing two different positive electrode materials – one possessing a high energy density, but a low rate capability and another capable of high rate output, but a lower energy density – is a concept that has been investigated for other applications. It is now starting to be applied to medical device batteries with diverse power requirements.
There is a focus on the batteries designed for a few of the more common applications – implantable cardiac rhythm management (cardiac pacemakers and defibrillators), pain management, and hearing loss devices. There are a substantial number of wearable and implantable medical devices powered by batteries.
