Stimulation Electrode

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

This invention relates to a stimulation electrode designed for use in medical devices that treat neurological or psychiatric conditions (such as Parkinson's disease or epilepsy) by delivering electrical stimulation to targeted areas in the brain or spinal cord. The electrode features a shaft with several ring-shaped stimulation contact surfaces that are closely spaced around its circumference, with the distance between adjacent contacts kept to less than 10% of the shaft's circumference. These contacts can be individually controlled to deliver precise, localized stimulation patterns, enabling a focused and flexible therapeutic effect.

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

• Deep brain stimulation for the treatment of movement disorders such as Parkinson’s disease, essential tremor, and dystonia.
• Neuromodulation therapy for epilepsy, OCD, depression, and other psychiatric or neurological disorders.
• Spinal cord stimulation for chronic pain management.
• Targeted electrical stimulation in research settings to study brain or nervous system function.
• Development of adaptive, closed-loop neurostimulation systems that adjust therapy in real-time based on neural signals.

BenefitsContent extracted from patent full text and abstract with AI.

• Allows very precise and localized delivery of electrical stimulation, minimizing unwanted side effects by targeting only specific neuron populations.
• Multiple contacts and the ability to independently control them offer flexibility to tailor the stimulation pattern to each patient's needs or specific disease targets.
• Reduces the risk of stimulating adjacent, non-target tissue, improving safety and therapeutic outcomes.
• Suitable for both open-loop and closed-loop stimulation setups, where feedback sensors can dynamically adjust stimulation parameters.
• Enables the creation of complex stimulation patterns to desynchronize pathological neuronal activity, potentially offering more effective long-term therapies.

Patent Abstract

The invention relates to a stimulation electrode (11) having an electrode shaft (14) and a plurality of stimulation contact surfaces (15) disposed in a first segment (17) of the electrode shaft (14) as ring segments at a distance from each other, wherein the distance between any two adjacent stimulation contact surfaces (15) of the first segment (17) is not greater than 10% of the circumference of the electrode shaft (14) in the first segment (17).
