Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices, particularly cochlear implants, face challenges in accurately determining the optimal insertion and positioning of electrode arrays within the cochlea, leading to potential complications and suboptimal performance due to factors like air bubbles, open electrodes, and electrode extrusion, which current methods struggle to address effectively.
Innovation Solution
The method involves obtaining and analyzing impedance values at different temporal locations within the cochlea using a cochlear implant electrode array, comparing these values over time, and implementing treatments or adjustments based on the analysis to ensure proper electrode positioning and function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional implantation methods are used for cochlear implants, then the procedure can be completed with standard techniques, but accurate determination of optimal electrode positioning is not achieved, leading to complications and suboptimal performance
Solution Approach 1:
The patent applies preliminary action by measuring impedance values at multiple temporal locations (first temporal location and second temporal location after the first) to predict future complications before they occur. This allows the system to identify electrodes at risk of extrusion or malfunction early in the implantation process, enabling preventive measures to be taken to ensure optimal positioning and performance.
Solution Approach 2:
The patent implements feedback by continuously monitoring impedance values over time and using this information to evaluate electrode performance. The system compares impedance measurements taken at different temporal locations and uses this feedback to determine whether complications are developing, allowing for real-time adjustments or interventions to maintain optimal implant performance.
2Reliability
If impedance values are measured at multiple temporal locations, then predictive capability for complications is improved, but the complexity of data collection and analysis increases
Solution Approach 1:
The patent applies segmentation by dividing the temporal monitoring period into distinct measurement points (first temporal location and second temporal location after the first). This segmentation allows the system to collect impedance data at specific intervals rather than continuously, making the data collection process more manageable while still providing sufficient information for predictive analysis of complications.
Solution Approach 2:
The patent implements self-service by using the cochlear implant's own impedance measurement capabilities to monitor its own performance and predict complications. The system leverages existing components (electrode array, signal processor) to conduct impedance measurements without requiring external diagnostic equipment, thereby reducing overall system complexity while maintaining predictive accuracy.
