  • Patent number: 10188871
    Abstract: A flat optogenetic cuff interface (FOCI) is configured for functional optical stimulation of axons in a single fascicle of a peripheral nerve bundle in which the axons have been genetically modified to express light sensitive proteins for excitation or inhibition of the nerves. The FOCI is configured to gradually reshape the single fascicle to a final height between 0.2 mm and 0.5 mm by reorganizing the individual axons within the fascicle without reshaping (and damaging) the individual axons. The FOCI facilitates stimulation of axons over the entire cross-section of the reshaped fascicle within the power limitations for pulsed laser energy. An electrical interface may be included to sense nerve activity of either the stimulated axons to provide closed-loop feedback to control the optical sources or stimulated axons of a different modality to record the response.

  • Publication number: 20070244523
    Abstract: A method for selective electrical stimulation of a retina for application in a visual neuralprosthesis. The method includes application of an asymmetrical, charge-balance biphasic waveform to increase the receptivity of selected cells to a subsequent stimulus, and then electrically stimulating to those selected cells to induce either a punctuate phosphene (perceived spot of light in the visual field) or a streak phosphene (streak of light in the visual field). A waveform having a sub-threshold anodic pulse followed by a supra-threshold cathodic pulse induces the punctuate phosphene, and a sub-threshold cathodic pulse followed by a supra-threshold anodic pulse induces the streak phosphene.

  • Publication number: 20070112402
    Abstract: Electrode Systems and Related Methods for Providing Therapeutic Differential Tissue Stimulation. According to one aspect, an electrode system for providing therapeutic differential tissue stimulation includes an electrode body. A plurality of electrode segments are positioned along the electrode body. The electrode segments are predetermined shapes and sizes that produce a predetermined electrical field for stimulating predetermined portions of tissue, and each of the electrode segments includes an outer surface which is exposed from the electrode body for coupling to tissue. A lead is connected to each of the electrode segments for use in applying a common electrical signal to the electrode segments.

  • Publication number: 20060184208
    Abstract: Apparatus for control of physiological functions, including physiological functions of the urinary tract, using at least one electrode sized and configured to be located on, in, or near a targeted component of the pudendal nerve, and/or its branch(es), and/or its spinal root(s). The apparatus includes a controller coupled to the electrode to apply an electrical signal having an amplitude to the electrode at a selected frequency to stimulate the targeted component. The controller operates in a first mode to apply a first frequency or range of frequencies without substantially changing the amplitude for achieving a first physiologic response (e.g., controlling urinary continence) and the controller operates in a second mode to apply a second frequency or range of frequencies, different than the first frequency, for achieving a second physiologic response different than the first physiologic response (e.g., controlling micturition).

  • Publication number: 20050222636
    Abstract: Systems and methods selectively stimulate components of the pudendal nerve away from the sacral root to evoke desired physiologic responses in persons who lack the ability to otherwise produce these responses—e.g., maintain continence and/or produce micturition, and/or provide male/female sexuality responses, and/or provide bowel responses. The systems and methods use a multiple electrode array, or individual electrodes, placed on, in, or near the pudendal nerve. The electrode array, or individual electrodes, in association with a pulse generator, provide selective stimulation of individual fascicles within the pudendal nerve, to achieve different physiologic responses.
