Electrogram Set Determination for Atrial Fibrillation Lesion Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intravascular or percutaneous medical procedures for treating atrial fibrillation are complex due to the difficulty in creating accurate lesions within the heart, and the excessive amount of information and electrograms presented to physicians during these procedures, making it time-consuming and risky to understand the efficacy of lesion patterns.
Innovation Solution
A medical system that includes a data processing device system, an input-output device system, and a memory device system, which configures the data processing device to select a first transducer set for tissue ablative energy transmission and determine a second transducer set for electrogram recording, allowing for the efficient display of relevant electrogram information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple transducers are used to record electrograms during intravascular or percutaneous procedures, then the amount of information available to physicians increases, but the complexity of interpreting the data and the time required to assess lesion efficacy increases
Solution Approach 1:
The patent segments the large set of electrogram signals from multiple transducers into smaller, manageable subsets for display. The system divides and conquers the information overload by showing only relevant portions of electrogram data at any given time, allowing physicians to assess lesion efficacy without being overwhelmed by excessive information.
Solution Approach 2:
The system extracts and displays only the most relevant electrogram information needed for assessing lesion efficacy. By selectively presenting critical data subsets rather than all available electrogram signals, the system removes unnecessary information complexity while preserving essential diagnostic value.
2Manufacturing precision
If multiple transducers are deployed for tissue ablation and electrogram recording, then the capability to create accurate lesion patterns improves, but the difficulty of managing and interpreting electrogram data increases
Solution Approach 1:
The system applies local quality by providing customized, location-specific electrogram displays based on transducer position and lesion target. Different regions of interest receive tailored information presentation, showing electrograms most relevant to each specific lesion site rather than uniform displays of all signals, thereby reducing interpretation difficulty while maintaining lesion placement accuracy.
Solution Approach 2:
The system performs preliminary organization and filtering of electrogram data before presentation to the physician. By pre-processing and arranging electrogram signals in clinically relevant configurations based on transducer positions and lesion targets, the system reduces the cognitive load required for interpretation while preserving the precision needed for accurate lesion creation.
3Reliability
If comprehensive electrogram monitoring is performed during percutaneous procedures, then the ability to assess lesion efficacy improves, but the time required to review data and make clinical decisions increases
Solution Approach 1:
The system employs partial action by displaying only the necessary subset of electrogram data required for reliable lesion efficacy assessment. Rather than requiring review of all available electrogram signals, the system presents sufficient information to make accurate clinical decisions, reducing procedure time while maintaining assessment reliability.
Solution Approach 2:
The system performs preliminary organization and prioritization of electrogram data before clinical review. By pre-arranging electrograms in clinically relevant sequences and highlighting key signals, the system enables rapid assessment of lesion efficacy without requiring time-consuming review of all available data, thus reducing procedure time while maintaining reliability.

AI summary
A medical system may be configured to determine, at least in response to a selection or activation of a first transducer set, a second transducer set satisfying a determined positional relationship with respect to the first transducer set, each transducer in the second transducer set configured to record a respective electrogram, and the second transducer set mutually exclusive with the first transducer set. The medical system may be configured to visually display or increase a visual prominence of a portion of an electrogram set derived from or corresponding to the determined second transducer set.
