Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neurostimulation systems face challenges in predicting and mitigating side effects, particularly latent or delayed effects, which can occur after brief testing and may not be immediately observable.
Innovation Solution
A system comprising one or more processors and memory devices that obtain neurostimulation programming parameters and source data defining treatment effects in an anatomical area. The system models the use of these parameters to predict side effects, outputting information on their characteristics, and can update programming based on observed side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If brief testing of programming parameters is performed in clinical settings, then productivity is improved, but reliability deteriorates due to undetected latent side effects
Solution Approach 1:
The system performs preliminary computational modeling of side effects before actual neurostimulation treatment begins. By using pre-collected source data and computational models to predict potential side effects of programming parameters, the system identifies risky parameter combinations in advance, allowing clinicians to avoid them without extensive brief testing that would still carry risks of missing latent side effects.
2Reliability
If comprehensive testing of all programming parameter combinations is performed, then reliability is improved, but productivity deteriorates due to time and resource constraints
Solution Approach 1:
Instead of performing exhaustive testing of all possible programming parameter combinations, the system uses computational models to predict side effects for all parameters and then focuses clinical testing only on those parameters with high predicted side effect risk. This partial action approach achieves sufficient reliability by concentrating resources on the most problematic parameters while avoiding the impracticality of comprehensive testing of all parameters.
Solution Approach 2:
The system creates computational models that replicate and predict the effects of neurostimulation programming parameters without requiring actual physical testing of each parameter combination. These virtual models serve as copies that can be tested extensively in silico, identifying risky parameters that then guide limited physical testing in clinical settings.
3Reliability
If neurostimulation programming parameters are optimized for treatment efficacy, then the therapeutic effect is improved, but harmful factors increase due to potential side effects in adjacent anatomical areas
Solution Approach 1:
The system applies preliminary anti-action by using computational models to predict and identify potential side effects in adjacent anatomical areas before optimizing neurostimulation programming parameters for treatment efficacy. By anticipating harmful effects in advance through modeling, the system can adjust parameter optimization strategies to avoid configurations that would cause side effects while still achieving therapeutic goals in the target area.
Solution Approach 2:
The system applies local quality by differentiating between the target anatomical area requiring treatment and adjacent areas that may experience side effects. The computational modeling approach allows for spatially-resolved prediction of stimulation effects, enabling optimization of programming parameters to maximize therapeutic effect in the target area while minimizing activation of adjacent anatomical structures that would cause side effects.
