Radio frequency (RF) energy is transmitted through the application of a RF signal to an external RF energy interface, where the RF signal oscillates at a frequency in an energy transmission band. The transmitted RF energy is received at an implanted medical device, and energy derived from the received RF energy is stored in a direct current (DC) energy storage component of the device. A therapeutic output signal is generated from the stored energy and delivered by the implantable medical device to a patient through one or more electrodes. The therapeutic output signal is configurable to provide either one of RF stimulation therapy and RF ablation therapy, and comprises pulses of an RF signal oscillating at a frequency in a therapy band that is greater than the energy transmission band.
