Abstract
Systems, devices and methods allow inductive recharging of a power source located within or coupled to an implantable medical device while the device is implanted in a patient. The implantable devices in some examples include a multi-axis antenna having a plurality of coil windings arranged orthogonal to one another. The multi-axis antenna configured to generate at least a minimum level of induced current for recharging a power source of the implanted medical device regardless of the orientation of a direction of a magnetic field imposed on the multi-axis antenna relative to an orientation of the implanted medical device and the multi-axis antenna for a given energy level of the imposed magnetic field.
