Solution Overview
Problem
Current methods for modulating neural activity in peripheral neural structures lack the ability to control conduction effectively during different activity states, leading to undesired effects such as numbness, discomfort, and interference with autonomic functions.
Innovation Solution
A method and system that produce reversible conduction blocks in peripheral neural structures using electrical fields, distinguishing between activity states to apply blocking stimuli and reverse them as needed, allowing for controlled modulation of neural activity to achieve desired effects like immune or inflammatory response modulation without inconvenient side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous blocking stimulus is applied to peripheral neural structures, then conduction block is achieved, but numbness and discomfort occur
Solution Approach 1:
The patent applies periodic blocking stimuli synchronized with the subject's activity states rather than continuous stimulation. The system detects activity states and delivers blocking stimuli only during appropriate periods, creating a rhythmic on-off pattern that maintains conduction block effectiveness while allowing neural recovery periods that prevent numbness and discomfort
Solution Approach 2:
The system dynamically adjusts the blocking stimulus delivery based on real-time detection of activity states. The stimulus parameters (timing, duration, intensity) are modified according to the subject's physiological state, transitioning from static continuous blocking to dynamic state-dependent blocking, thereby maintaining effectiveness while reducing harmful side effects
2Reliability
If blocking stimulus is applied during all activity states, then conduction block is maintained, but autonomic functions are interfered with
Solution Approach 1:
The patent applies blocking stimuli selectively to specific activity states rather than uniformly to all states. Different quality of stimulus application is used depending on the local physiological context - blocking during sensory/motor activity states while preserving conduction during autonomic activity states, thereby achieving localized control that prevents autonomic interference
Solution Approach 2:
The system changes the parameter of stimulus application timing based on activity state detection. By monitoring physiological parameters and adjusting when blocking stimuli are delivered, the system modifies the temporal parameters of neural modulation to coincide with appropriate activity states, avoiding periods when autonomic functions are active
3Reliability
If blocking stimulus is applied without activity state discrimination, then conduction block is achieved, but desired precision in immune or inflammatory response modulation is lost
Solution Approach 1:
The system incorporates feedback from activity state detection to control blocking stimulus delivery. By continuously monitoring physiological signals and using this feedback to determine when to apply blocking stimuli, the system achieves precise temporal control over neural conduction, enabling accurate modulation of immune or inflammatory responses based on real-time physiological state
Solution Approach 2:
The system performs preliminary detection of activity states before delivering blocking stimuli. By anticipating the appropriate timing for stimulus application based on detected physiological state transitions, the system prepares and delivers blocking stimuli at optimal moments, enhancing the precision of immune or inflammatory response modulation
