Cardiac Map Segmentation for Automated Ablation Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cardiac ablation systems require physicians to manually set and manage multiple parameters during procedures, which is time-consuming and error-prone, especially when dealing with varied ablation equipment and individual patient anatomy.
Innovation Solution
A cardiac ablation system that includes an ablation probe with a tracking module and processing circuitry to segment heart chamber maps into regions, retrieve and apply default ablation-parameter sets based on the tracked position, allowing for user input and updates to optimize ablation procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physicians manually set and manage ablation parameters during procedures, then they can customize parameters for each specific case, but the process becomes time-consuming and error-prone
Solution Approach 1:
The system performs self-service by automatically segmenting the heart chamber map into anatomical regions and retrieving appropriate ablation parameter sets based on the ablation element's tracked position and type, eliminating the need for physicians to manually set each parameter while ensuring consistent, accurate parameter application
Solution Approach 2:
The system performs preliminary actions by pre-segmenting the heart chamber map into anatomical regions before the ablation procedure begins, and pre-storing multiple ablation parameter sets corresponding to different regions and equipment types, so that during the procedure parameters are immediately available without manual configuration
2Productivity
If default ablation parameter sets are automatically applied based on tracked position, then procedural time is reduced and errors are minimized, but the system complexity increases
Solution Approach 1:
The system achieves universality by designing a single integrated platform that handles multiple functions: automatic map segmentation into anatomical regions, tracking of ablation element position, identification of equipment type, retrieval of appropriate parameter sets, and automatic application of parameters, replacing multiple separate manual processes with one unified system
Solution Approach 2:
The processing circuitry acts as an intermediary between the tracking module and the ablation parameter storage, automatically matching the tracked position and equipment type to retrieve the appropriate parameter set from stored data, thereby simplifying the interface the physician must manage while handling complex matching logic in the background
3Measurement precision
If region-specific default parameter sets are used, then ablation precision is enhanced, but the quantity of data to be managed increases
Solution Approach 1:
The system applies segmentation by dividing the heart chamber map into distinct anatomical regions (such as left atrium, right ventricle, etc.), with each region having its own optimized ablation parameter set, allowing precise parameter selection based on the specific anatomical location while organizing data in a structured, manageable way

AI summary
One embodiment includes a cardiac ablation system, including an ablation probe including at least one ablation application element to ablate tissue in a chamber of a heart of a living subject, a tracking module to track a position of the at least one ablation application element within the heart, a memory to store a map of the chamber of the heart and store a different, respective default ablation-parameter set for each different region of the chamber, and processing circuitry to segment the map of the chamber into the different regions, receive a user input indicative of commencement of an ablation procedure, identify, responsively to the tracked position, a region of the chamber with which the at least one ablation application element is in contact, retrieve the respective default ablation-parameter set assigned to the identified region, and apply the retrieved default ablation-parameter set in controlling the ablation procedure.
