Abstract
Devices, systems, and methods for coupling with an implantable neurostimulator for delivering one or more electrical pulses to a target region within a patient's body are disclosed herein. A device, such as a charger, can include: a power source for storing electrical energy; a resonant circuit that can have a plurality of selectable natural frequencies; a driver coupled to the power source and the resonant circuit; and a processor coupled to the resonant circuit to control the natural frequency of the resonant circuit. The processor can determine the natural frequency of the implantable neurostimulator, and can control the resonant circuit according to the determined natural frequency of the neurostimulator.
