Solution Overview
Problem
Identifying suitable stimulation parameters for implantable electrical stimulation systems is challenging due to the complexity of programming multiple electrodes and the need for precise targeting of therapeutic effects while minimizing side effects, particularly in applications like deep brain stimulation.
Innovation Solution
Generating a clinical effects map that displays therapeutic and side effect results using a radius of the stimulation field, allowing for precise programming by mapping clinical responses to spatial regions around the lead, facilitated by three-dimensional or two-dimensional representations with graphical anatomical features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple electrodes are programmed to provide comprehensive stimulation coverage, then the therapeutic effectiveness is improved, but the complexity of programming and the risk of side effects increase
Solution Approach 1:
The stimulation field is segmented into multiple radial zones around the lead, with each zone corresponding to a specific anatomical structure or functional region. This segmentation allows the system to independently control and optimize stimulation parameters for each zone, thereby achieving comprehensive therapeutic coverage while simplifying the programming process through structured regional control rather than managing multiple electrodes independently.
Solution Approach 2:
The patent introduces a radial dimension to the stimulation field representation, organizing the stimulation space into concentric zones around the lead rather than traditional linear or planar arrangements. This dimensional transformation enables more intuitive mapping of stimulation effects to anatomical structures, reducing programming complexity while maintaining comprehensive coverage through three-dimensional spatial organization.
2Measurement precision
If stimulation parameters are optimized to target specific therapeutic regions, then the precision of therapeutic effects is improved, but the difficulty of detecting and measuring clinical responses increases
Solution Approach 1:
The patent introduces clinical effect maps as an intermediary visual representation that bridges the gap between stimulation parameters and clinical responses. These maps serve as a mediator that translates complex physiological responses into intuitive visual patterns, allowing clinicians to detect and measure clinical effects more easily while maintaining precise control over stimulation parameters through the mapped representation.
Solution Approach 2:
The patent employs color-coded representations in the clinical effect maps to indicate different types and intensities of clinical responses. By using color changes to encode therapeutic effects, side effects, and their intensities, the system transforms difficult-to-measure physiological data into visually intuitive information, thereby reducing the difficulty of detecting and measuring clinical responses while preserving targeting precision.
3Measurement precision
If a three-dimensional representation of the stimulation field is used to map clinical responses to spatial regions, then the precision of therapeutic targeting is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The three-dimensional stimulation field is segmented into discrete radial zones and angular sectors, creating a modular representation that reduces computational complexity. This segmentation allows the system to process and display clinical effect data in manageable portions while maintaining the precision benefits of three-dimensional spatial mapping, thereby reducing overall system complexity without sacrificing measurement precision.
