3D Ablation Tag Mapping for Multi-Electrode Session Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The visualization of ablation sessions using multi-electrode catheters, such as bipolar Pulsed-Field Ablation catheters, results in a cluttered display of ablation tags in a 3D space, making it difficult for physicians to understand the relationship between tags and correlate them to specific ablation sessions, hindering holistic analysis.
Innovation Solution
A 3D graphical representation is generated that connects pairs of adjacent electrodes with distinct indications for delivered and undelivered ablation energy, using different distinguishing features for each type of indication, along with additional information like ablation count, session order, and timing, to provide clear visualization and organization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple ablation tags are displayed in 3D space to represent ablation sessions, then complete ablation information is captured, but the display becomes cluttered and difficult to analyze
Solution Approach 1:
The patent segments the continuous ablation procedure into discrete, numbered ablation sessions. Each session is visually separated and organized in the 3D display, allowing physicians to analyze individual sessions without being overwhelmed by the complete set of tags. This segmentation transforms the cluttered mass of tags into organized, analyzable units.
Solution Approach 2:
The patent utilizes the third dimension (depth/z-axis) to organize ablation sessions vertically or spatially separated. By stacking or arranging session representations in 3D space rather than flattening them, the system maintains complete information while preventing visual clutter through spatial distribution across multiple dimensions.
2Quantity of substance
If all ablation tags are displayed without differentiation, then complete data is shown, but relationship between tags and sessions cannot be correlated
Solution Approach 1:
The patent applies different colors to represent different ablation sessions or states. Each session or tag type is assigned a distinct color code, enabling physicians to quickly correlate tags with their respective sessions and understand the spatial distribution of different ablation applications without losing any data.
Solution Approach 2:
The patent segments the display into session-specific groups or layers, where each session's tags are visually clustered or labeled with session identifiers. This segmentation preserves complete tag data while adding organizational structure that maintains the relationship between individual tags and their parent sessions.
3Loss of information
If detailed information about each ablation tag is provided, then complete procedural data is available, but overall holistic analysis becomes difficult
Solution Approach 1:
The patent merges multiple individual tag representations into consolidated session views or summary displays. By combining detailed tag information into aggregated session representations, the system preserves complete procedural data while providing a higher-level overview that enables holistic analysis of the entire ablation procedure.
Solution Approach 2:
The patent organizes detailed tag information along additional dimensional axes (such as time, session number, or spatial coordinates) rather than presenting it in a flat, overwhelming format. This multi-dimensional organization allows physicians to drill down into specific details when needed while maintaining an overview capability for holistic analysis.

AI summary
A method may comprise receiving, by a processor from one or more sensors, a three-dimensional (3D) position of each of a plurality of electrodes of a catheter during an ablation session, generating, by the processor, a 3D graphical representation identifying a position of each of the plurality of electrodes with a first indication, and connecting, by the processor, pairs of adjacent first indications with a second indication in the constellation-like 3D graphical representation. The second indications may indicate locations between electrodes where energy was delivered. The method may comprise displaying, by the processor on a display device, the 3D graphical representation comprising the first indications and the second indications. The method may comprise identifying pairs of adjacent first indications, that are not connected by a second indication, with a third indication, which may indicate locations between electrodes where energy was not delivered.
