Solution Overview

Problem

Current medical systems lack an effective method to present and process electrophysiological information in a way that enhances diagnosis and treatment efforts, particularly in interventional procedures, by correlating imaging and physiological data to provide actionable insights for clinicians.

Innovation Solution

A medical system that obtains three-dimensional anatomical renderings, calculates values from monophasic action potential signals, and displays graphical indicators to suggest treatment locations, integrating this information with electrocardiogram signals for real-time alerts and enhanced visualization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If electrophysiological information is obtained through multiple imaging modalities and physiological monitoring, then the quantity and quality of diagnostic information is improved, but the device complexity and difficulty of information integration increases

Engineering Contradiction:
Improveelectrophysiological information completenessVSAvoidsystem integration complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines multiple imaging modalities (fluoroscopy, CT, MRI) with electrophysiological monitoring systems into a single integrated platform. The system merges anatomical imaging data with electrical signal data, allowing simultaneous visualization of both structural and functional information on unified displays with synchronized timing, thereby reducing information loss without proportionally increasing operational complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated system serves multiple functions: it performs anatomical imaging, electrophysiological signal acquisition, real-time data correlation, and synchronized display across multiple modalities. This multi-functional approach consolidates what would otherwise require separate systems, addressing the contradiction by providing comprehensive information while managing system complexity through unified architecture

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If real-time electrophysiological monitoring is implemented during interventional procedures, then diagnostic accuracy and treatment precision are improved, but the ease of operation and information accessibility deteriorates

Engineering Contradiction:
Improveelectrophysiological measurement accuracyVSAvoidinformation accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent transforms complex electrophysiological data into visual representations by mapping electrical signals onto three-dimensional anatomical models. This dimensional transformation allows clinicians to view electrophysiological information in the spatial context of anatomical structures, making precise measurements accessible through intuitive visual displays rather than requiring interpretation of raw electrical signals

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The system creates visual copies or representations of electrophysiological data overlaid on anatomical images. By generating synchronized visual representations of electrical activity that mirror anatomical structures, the system makes precise measurements easily accessible through visual inspection of correlated displays, eliminating the need for complex signal interpretation while maintaining measurement accuracy

Inventive Principle:
Principle #26Copying

3Reliability

If multiple physiological parameters are monitored and correlated, then the quality of clinical decision-making is improved, but the loss of time for data processing and analysis increases

Engineering Contradiction:
Improveclinical decision-making qualityVSAvoiddata processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system continuously monitors and correlates multiple physiological parameters in real-time during interventional procedures. By maintaining continuous data acquisition and correlation across imaging and electrophysiological modalities without interruption, the system ensures that clinical decisions are based on the most current and comprehensive data available, improving reliability while minimizing time loss through automated real-time processing

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The integrated system provides real-time feedback by continuously correlating and displaying multiple physiological parameters together. The synchronized presentation of imaging and electrophysiological data creates immediate feedback loops that allow clinicians to observe relationships between anatomical changes and electrical activity in real-time, enabling rapid clinical decision-making without significant time loss for separate analysis

Inventive Principle:
Principle #23Feedback
