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 medical device in some examples include a receive antenna configuration that may include at least one infinity shaped receive coil. One or more of the receive coils may be affixed to a ferrite sheet formed having a curved shape that conforms to a curvature on an inner surface of a portion of a housing of the implantable medical device so that the ferrite sheet and the receive coil or coils may be positioned adjacent to some portion of the curved inner surface with the ferrite sheet positioned between the inner surface and the receive coil or coils.
