Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrophysiological diagnostic systems face limitations in accurately mapping complex heart rhythms, particularly unstable and intermittent arrhythmias, due to manual editing requirements, inaccurate geometry, and inability to simultaneously map bi-chamber or whole heart, especially during procedures like atrial fibrillation.
Innovation Solution
An integrated system that analyzes non-invasive electroanatomic data with intracardiac electrical data to identify and characterize arrhythmogenic zones, generating hybrid graphical maps that integrate distinct arrhythmogenic electrical activity with intracardiac signal characteristics, enabling precise diagnosis and treatment planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual editing of activation times is performed, then individual trace display is achieved, but mapping accuracy and stability deteriorate
Solution Approach 1:
The patent replaces manual mechanical editing operations with automated computer-based processing. The system automatically processes electrophysiological signals to generate activation times and maps, eliminating the need for manual editing while improving accuracy through algorithmic computation and digital signal processing.
2Object-affected harmful factors
If non-invasive signals alone are used, then patient safety is improved, but mapping precision and diagnostic accuracy deteriorate
Solution Approach 1:
The patent merges non-invasive body surface electrocardiographic signals with invasive intracardiac electrophysiological signals into a unified integrated mapping system. This combination allows the system to maintain patient safety benefits of non-invasive monitoring while achieving the diagnostic precision of invasive measurements through data fusion and correlation algorithms.
3Adaptability or versatility
If invasive catheters are placed at multiple locations, then comprehensive heart mapping is achieved, but procedure complexity and time increase
Solution Approach 1:
The patent implements a universal integrated mapping system that can perform both non-invasive body surface mapping and invasive intracardiac mapping through a single unified platform. The system is designed to handle multiple catheters simultaneously, processing signals from various heart chambers concurrently, thereby reducing overall procedure complexity despite comprehensive mapping capabilities.
Solution Approach 2:
The patent introduces a computer-based processing system as an intermediary that automatically manages and coordinates multiple catheter signals. This intermediary system handles signal acquisition, processing, and integration, reducing the manual coordination burden and simplifying the overall procedure while enabling comprehensive bi-chamber or whole-heart mapping.
4Ease of operation
If traditional EP recording systems are used, then individual trace display is achieved, but ability to map complex rhythms deteriorates
Solution Approach 1:
The patent transitions from traditional two-dimensional individual trace displays to multi-dimensional integrated maps that combine spatial information from multiple heart chambers with temporal electrophysiological data. This dimensional expansion allows simultaneous visualization of complex rhythms across the entire heart, providing comprehensive mapping capability for atrial fibrillation and other complex arrhythmias while maintaining ease of interpretation through graphical user interface displays.
