Abstract
A leadless Deep Brain Stimulation system includes an implantable stimulator configured to convert incoming acoustic energy into an electric stimulation signal. The acoustic energy is provided by one or more external transmitters acoustically coupled to a head of the subject. To focus ultrasound energy onto the location of the stimulator, a wireless beacon (including a piezoelectric receiving transducer and an RF emitting antenna) is incorporated with the stimulator for providing an electromagnetic feedback signal to the external controller. The external controller is configured to send an initial unfocused acoustic signal towards the stimulator and receive the electromagnetic radiofrequency feedback signal generated by the receiving piezotransducer when affected by the acoustic signal after reverberation in the skull. This signal is then time-reversed and used to send a second signal towards the stimulator. This signal is inherently focused on the site of the stimulator and is configured to carry sufficient energy to operate the stimulator for DBS purposes.
