Abstract
An inductive charging antenna for charging the power source of an active implantable medical device (AIMD) is described. The charging antenna is supported on the body fluid side of the feedthrough insulator, on the device side of the insulator or it is embedded inside the insulator. The charging antenna is connected to electronic circuits housed inside the medical device to charge the power source so that the device can deliver electrical stimulation to a patient and receive sensed biological signals from body tissue, among other functionalities. If the charging antenna is supported on the insulator body fluid side, it is made from a biocompatible material such as platinum. However, if the charging antenna is embedded inside the feedthrough insulator or is supported on the device side of the insulator, it can be made from a less expensive material that is not biocompatible, for example, copper.
