  • Publication number: 20220176129
    Abstract: A method of applying a neural stimulus with an implanted electrode array involves applying a sequence of stimuli configured to yield a therapeutic effect while suppressing psychophysical side effects. The stimuli sequence is configured such that a first stimulus recruits a portion of the fibre population, and a second stimulus is delivered within the refractory period following the first stimulus and the second stimulus being configured to recruit a further portion of the fibre population. Using an electrode array and suitable relative timing of the stimuli, ascending or descending volleys of evoked responses can be selectively synchronised or desynchronised to give directional control over responses evoked.

  • Publication number: 20220168574
    Abstract: An automated method of controlling neural stimulation. A neural stimulus is applied to a neural pathway in order to give rise to an evoked action potential on the neural pathway, and the stimulus is defined by at least one stimulus parameter. A neural compound action potential response evoked by the stimulus is measured. From the measured evoked response a feedback variable such as observed ECAP voltage (V) is derived. A feedback loop is completed by using the feedback variable to control the at least one stimulus parameter value for a future stimulus. The method adaptively compensates for changes in a gain of the feedback loop caused by electrode movement relative to the neural pathway. A compensating transfer function is applied to the feedback variable, the compensating transfer function being configured to compensate for both (i) a distance-dependent transfer function of stimulation, and (ii) a distance dependent transfer function of measurement which is distinct from (i).

  • Publication number: 20220062939
    Abstract: A self-cleaning filter apparatus includes a filter unit and a plunger unit. The filter unit includes a screen device; and a filter unit housing that houses the screen device. The plunger unit includes a rod end housing coupled to the filter unit housing; a plunger rod with a first plunger rod end positioned within the rod end housing and a second plunger rod end within the filter unit housing; and a plunger assembly secured to the second plunger rod end. During a first filter cleaning event segment, the plunger rod is configured to translate between a nominal position in which the plunger assembly is proximate the first screen device end and a cleaning position in which the plunger assembly is proximate the second screen device end. The plunger rod is configured to dislodge, at least in part, debris from within the screen device during at least the first filter cleaning event segment.

  • Publication number: 20210315502
    Abstract: An implantable device for estimating neural recruitment arising from a stimulus, has a plurality of electrodes. A stimulus source provides stimuli to be delivered from the electrodes to neural tissue. Measurement circuitry obtains a measurement of a neural signal sensed at the electrodes. A control unit is configured to control application of a selected stimulus to neural tissue using the stimulus electrodes; and after the selected neural stimulus, apply a probe stimulus having a short pulse width. A remnant neural response evoked by the probe stimulus is measured; and the control unit estimates from the remnant neural response a neural recruitment caused by the selected neural stimulus.
