Legal Citation
Summary of the Inventive Concept
An advanced neurostimulation system that dynamically adjusts stimulation parameters in response to real-time MRI/EMI interference detection, ensuring optimal therapy delivery and patient safety.
Background and Problem Solved
The original patent addresses the challenge of regulating current to provide active emulation of passive discharge in the presence of MRI/EMI interference. However, it relies on fixed stimulation parameters, which may not be effective in mitigating interference in dynamic environments. The new inventive concept solves this problem by introducing adaptive stimulation parameters that respond to real-time interference detection.
Detailed Description of the Inventive Concept
The adaptive neurostimulation system comprises a plurality of electrodes, including an active electrode and an anode electrode, positioned within a patient. The system detects MRI/EMI interference in real-time using a sensor and adjusts stimulation parameters of the active electrode accordingly. This is achieved through a neural network trained to predict optimal stimulation parameters based on historical interference patterns. The regulator circuit adjusts the stimulation parameters in real-time based on the predicted optimal parameters, ensuring optimal neurostimulation therapy delivery. The system can also incorporate a controller that adjusts stimulation parameters based on detected changes in a patient's neural activity in response to MRI/EMI interference.
Novelty and Inventive Step
The new inventive concept introduces a paradigm shift in neurostimulation technology by incorporating real-time interference detection and adaptive stimulation parameters. This is a significant departure from the original patent, which relies on fixed stimulation parameters. The use of a neural network to predict optimal stimulation parameters and the regulator circuit's real-time adjustments are novel and non-obvious features that provide a significant improvement over existing technologies.
Alternative Embodiments and Variations
Alternative embodiments of the adaptive neurostimulation system could include using different types of sensors or neural networks to detect MRI/EMI interference. Additionally, the system could be integrated with other medical devices, such as MRI machines, to provide real-time feedback and optimization. Variations of the system could also be designed for specific medical applications, such as deep brain stimulation or spinal cord stimulation.
Potential Commercial Applications and Market
The adaptive neurostimulation system has significant commercial potential in the medical device industry, particularly in the areas of neurology, neurosurgery, and psychiatry. The system's ability to provide optimal neurostimulation therapy in dynamic environments could lead to improved patient outcomes and reduced healthcare costs. The market for this technology is expected to grow as the demand for advanced neurostimulation systems increases.
