Device and Method for Stimulation of Neuronal Tissue by Means of Optical Stimuli

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes an implantable device with multiple stimulation units and a control unit designed to treat neurological disorders by delivering optical (light-based) stimuli to reset the phase of abnormally oscillating neurons. The device coordinates the timing of light stimulation across different units to better control neuronal activity.

Use CasesContent extracted from patent full text and abstract with AI.

• Treatment of neurological disorders such as epilepsy, where abnormal neuronal synchrony occurs
• Therapy for movement disorders like Parkinson's disease
• Potential use in research for investigating and controlling brain oscillations
• Restoring normal brain function in cases of brain injury or dysfunction involving pathological neural synchrony

BenefitsContent extracted from patent full text and abstract with AI.

• Provides a precise, non-electrical method for neuromodulation using light
• Allows targeted and customizable stimulation of neuronal tissue
• Reduced risk of tissue damage compared to electrical stimulation methods
• May offer new treatment options for patients not responding to conventional therapies
• Improved control over abnormal brain activity by using phase-resetting stimuli at different times

Patent Abstract

A device with a control unit and a plurality of stimulation units configured to be implanted in the body of a patient and generate optical stimuli, wherein the optical stimuli reset the phase of the neuronal activity of the neurons during the stimulation of neurons exhibiting abnormally synchronous and oscillatory neuronal activity, and the control unit is configured to actuate the stimulation units such that at least two of the stimulation units reset the phases of the respectively stimulated neurons at different times.
