Solution Overview
Problem
Current cardiac rhythm management (CRM) devices face confusion in programming and data interpretation when implanted electrodes are positioned at non-standard locations, leading to incorrect recording and display of cardiac data.
Innovation Solution
A medical device system that downloads data from implanted devices, uses electrode location identification rules to determine actual electrode placements, and displays this information to users, allowing for accurate programming and data interpretation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrodes are placed at standard locations, then programming and data interpretation are straightforward, but the ability to achieve optimal therapeutic outcomes is limited
Solution Approach 1:
The system automatically detects and adapts to changes in electrode placement parameters by analyzing ECG morphology. When non-standard placement is detected, the system modifies its interpretation parameters and display labels to match the actual electrode locations, thereby maintaining ease of operation while enabling placement flexibility.
Solution Approach 2:
The system performs self-identification of electrode placement locations by automatically analyzing the ECG data morphology without requiring manual input from the operator. The processing circuitry autonomously determines electrode locations and configures the display accordingly, eliminating the need for manual setup while supporting both standard and nonstandard placements.
2Reliability
If electrodes are placed at alternate locations to achieve better outcomes, then therapeutic effectiveness improves, but confusion in programming and ECG interpretation occurs
Solution Approach 1:
The system dynamically changes its interpretation parameters based on detected electrode placement. When nonstandard placement is identified through ECG morphology analysis, the system adjusts its data interpretation algorithms and modifies display labels to accurately reflect the actual electrode locations, preventing information loss and maintaining clarity.
Solution Approach 2:
The system uses feedback from ECG morphology analysis to automatically determine electrode placement locations. This feedback mechanism allows the system to adapt its programming and display interpretation to match the actual physical electrode positions, ensuring that therapeutic effectiveness is maintained while avoiding confusion in data interpretation.
3Device complexity
If the system assumes standard electrode placement, then programming is simplified, but incorrect data interpretation occurs when nonstandard placement is used
Solution Approach 1:
The system automatically identifies electrode placement locations by analyzing ECG morphology without requiring manual configuration or simplifying assumptions. This self-service approach maintains low programming complexity while achieving high measurement precision in electrode location identification.
Solution Approach 2:
The system changes its operational parameters based on detected electrode placement. Rather than assuming standard placement, the system automatically adjusts its interpretation parameters to match the actual electrode locations identified through ECG analysis, thereby maintaining simplicity while improving accuracy.
