US Patent 10994139 Devices, systems, and methods for stimulation therapy

Generally discussed herein are systems, devices, and methods for providing a therapy or data signal using an implantable device. A method of providing intermittent stimulation by a stimulation system can include providing, by an external device of the stimulation system, radio frequency first signals to an implantable device of the stimulation system, the implantable device including an electrode and the first signals causing the implantable device to provide electrical stimulation through the electrode for a first time duration, determining, at the external device, that the implantable device is out of range of a transmission from the external device, determining, at the external device, that the implantable device is within range of the transmission from the external device, and providing, by an external device of the stimulation system, radio frequency second signals to the implantable device of the stimulation system, the second signals causing the implantable device to provide electrical stimulation through the electrode for a third time duration.
