Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If invasive catheter-based ablation is used to treat cardiac arrhythmias, then treatment effectiveness can be achieved, but procedural risks and complications increase significantly
Solution Approach 1:
The patent replaces the mechanical invasive catheter-based system with a noninvasive acoustic system using focused ultrasound waves to ablate arrhythmogenic tissue, eliminating the need for physical catheter insertion through blood vessels while maintaining treatment effectiveness
Solution Approach 2:
The patent introduces a noninvasive imaging and mapping system as an intermediary to precisely locate arrhythmogenic substrates before applying focused acoustic energy, enabling accurate targeting without direct mechanical access to the heart tissue
2Measurement precision
If invasive mapping procedures are performed to identify arrhythmia targets, then diagnostic accuracy improves, but procedural complexity and patient risk increase
Solution Approach 1:
The patent replaces invasive mechanical mapping catheters with noninvasive electrocardiographic imaging (ECGI) and acoustic mapping techniques that reconstruct cardiac electrical activity and identify arrhythmogenic substrates through mathematical algorithms and surface electrode arrays
Solution Approach 2:
The patent creates a virtual three-dimensional model (copy) of the heart's electrical activity and anatomical structure through noninvasive imaging, allowing precise identification and targeting of arrhythmogenic tissue without physical intrusion into the cardiac chambers
3Reliability
If traditional invasive ablation procedures are used, then arrhythmia treatment can be achieved, but procedure duration and patient recovery time increase
Solution Approach 1:
The patent performs noninvasive three-dimensional mapping and precise localization of arrhythmogenic substrates before treatment delivery, allowing for optimized treatment planning and reduced procedure time when compared to intra-procedural mapping required in invasive approaches
