Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical procedures using intrabody probes for navigating body cavities face challenges in accurately determining anatomical identities, leading to potential complications due to reliance on incomplete geometrical information and the risk of misidentification, especially in complex interventions like trans-septal passage.
Innovation Solution
A method and apparatus that utilize a combination of anatomical schemas, machine learning, and real-time data from intrabody probes to determine anatomical identities by selecting rules based on operational contexts and applying them to measured properties, enabling accurate identification and guiding navigation or actions within body cavities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If geometrical information alone is used for anatomical identification, then the navigation process is simple, but the accuracy of anatomical identification deteriorates leading to potential misidentification
Solution Approach 1:
The patent combines multiple information sources including geometrical information, electrical properties, and operational context into a unified anatomical identification system. This integration allows the system to leverage diverse data types to improve identification accuracy while managing complexity through systematic combination of measurement modalities.
Solution Approach 2:
The patent introduces an anatomical schema as an intermediary framework that organizes and integrates multiple measurement types. The schema acts as a mediator between raw measurement data and final anatomical identification, providing a structured approach to combining geometrical and electrical properties with operational context.
2Reliability
If multiple measurement types are integrated for anatomical identification, then the reliability of identification improves, but the device complexity increases
Solution Approach 1:
The patent segments the anatomical identification process into distinct functional components: geometrical measurement, electrical property measurement, operational context tracking, and integrated analysis. This segmentation allows each component to be optimized independently while maintaining overall system reliability through their coordinated integration.
Solution Approach 2:
The patent creates a multi-functional identification system that can process multiple measurement types (geometrical, electrical, contextual) through a unified analytical framework. The anatomical schema serves as a universal structure that accommodates diverse measurement modalities, enabling the system to adapt to different measurement combinations without requiring separate processing paths.
3Measurement precision
If real-time operational context is considered in identification, then the precision of anatomical identification improves, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary organization of operational context data and measurement data before final anatomical identification. By pre-processing and structuring the data according to the anatomical schema framework, the system reduces the complexity of the final integration step while maintaining high identification precision through comprehensive data consideration.
Data Source
AI summary
Methods and systems for position determination of an intrabody probe, targets of an intrabody probe, and or actions to be performed using an intrabody probe are described. In some embodiments, an anatomy being navigated and/or mapped is described by a rule-based schema relating different anatomically identified structures to one another according to their ability to help identify and/or locate one another. Additionally, in some embodiments, data recorded from the intrabody probe is processed according to schema rules in order to provide anatomical identification of the anatomical region which the intrabody probe is sampling, optionally without performing detailed mapping, and/or prior to the availability of detailed mapping of anatomical geometry.
