Publication number: 20230414954Abstract: A wireless multi-channel implantable device. In some embodiments, the system includes: a wireless reception element, for receiving power wirelessly through tissue of a subject; a power management and storage circuit, for storing a portion of the received power; and a control circuit for controlling the delivery of current from the power management and storage circuit to each of a plurality of stimulation electrodes individually, based on a modulation of the received power.Type: ApplicationFiled: June 27, 2023Publication date: December 28, 2023Applicant: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Jennifer BLAIN CHRISTEN, Shiyi LIU, Ahmed Abed BENBUK, Daniel GULICK

Patent number: 11464989Abstract: A system for providing neurostimulation includes an external device (“external exciter”) and an implanted device. The external exciter includes an energy source which inductively powers the implanted device. Examples of such external exciters include devices having at least one of: ultrasonic transducers, Radio Frequency (RF) transmitters, and solar cells. The implanted device includes circuitry that limits its maximum energy output to a predetermined saturation threshold such that excess stimulation from the external exciter does not raise the output of the implanted device beyond the saturation threshold. The output signal of the external exciter is then pulse-width modulated in order to produce a desired amount of output stimulation from the implanted device to stimulate the bioelectrically excitable tissue at a desired level.Type: GrantFiled: July 18, 2019Date of Patent: October 11, 2022Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Bruce C. Towe, Daniel Gulick

Patent number: 11400318Abstract: An apparatus, system, and method for neurostimulation by high frequency ultrasound. In one embodiment, an apparatus includes a pulse generator, an ultrasound transducer coupled to the pulse generator, and an implantable stimulator. The implantable stimulator may include a piezoelectric element configured to convert ultrasound signals from the ultrasound transducer into electrical signals, a rectifier configured to convert alternating current from the piezoelectric element to a monophasic current, a capacitor coupled to the rectifier, and a first electrode and a second electrode coupled to the rectifier and capacitor and configured to transmit the monophasic current to body tissue. In addition, the apparatus may include a current-limiting circuit configured to limit the amount of current transmitted to the body tissue.Type: GrantFiled: March 25, 2019Date of Patent: August 2, 2022Assignee: Arizona Board of Regents on Behalf of Arizona State UniversityInventors: Bruce C. Towe, Daniel Gulick
