Zi-Ping Fang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11883670
    Abstract: Systems and methods for producing asynchronous neural responses to treat pain and/or other patient conditions are disclosed. A method in accordance with a particular embodiment includes selecting a target stimulation frequency that is above a threshold frequency, with the threshold frequency corresponding to a refractory period for neurons of a target sensory neural population. The method can further include producing a patient sensation of paresthesia by directing an electrical signal to multiple sensory neurons of the target sensory neural population at the stimulation frequency, with individual neurons of the sensory neural population completing corresponding individual refractory periods at different times, resulting in an asynchronous sensory neuron response to the electrical signal.

  • Publication number: 20240001122
    Abstract: Methods and apparatuses for setting a therapeutic dose of a neuromodulator implanted into a patient. The therapeutic dose typically includes a therapeutic dose duration including a ramp-up time to reach a peak modulation voltage and a sustained peak modulation time during which the voltage is sustained at the peak modulation voltage. The methods and apparatuses may use a testing ramp to identify a peak modulation voltage that is patient-specific and provides a maximized therapeutic effect while remaining comfortably tolerable by the patient during the application of energy by the neuromodulator.
