Legal Citation
Summary of the Inventive Concept
An improved system for finding the origin of a single-source arrythmia, utilizing advanced mapping, LAT-derived distance calculations, and real-time probe adjustments to provide more accurate and efficient localization.
Background and Problem Solved
The original patent disclosed a method for finding the origin of an arrythmia, but it had limitations in terms of accuracy and efficiency. The new inventive concept addresses these limitations by introducing advanced mapping and LAT-derived distance calculations, enabling more precise localization of the arrythmia origin.
Detailed Description of the Inventive Concept
The enhanced system comprises a mapping module to generate a detailed map of the heart chamber where the single-source arrythmia is present. A processing module calculates local activation times (LATs) over the surface of the chamber and determines the origin of the arrythmia based on LAT-derived distances from at least two pairs of points on the surface. The system can also incorporate machine learning algorithms to optimize the origin location. Additionally, the probe is adapted to adjust its position in real-time based on the calculated origin location, ensuring more accurate and efficient localization.
Novelty and Inventive Step
The new inventive concept introduces the use of advanced mapping, LAT-derived distance calculations, and real-time probe adjustments, which are not present in the original patent. These features provide a more accurate and efficient method for localizing the origin of a single-source arrythmia.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include the use of different mapping modalities, such as MRI or CT scans, or the integration of additional sensors to provide more accurate LAT measurements. Variations of the system could also be designed for use in different heart chambers or for localizing origins of other types of arrythmias.
Potential Commercial Applications and Market
The enhanced system for localizing cardiac arrythmia origins has significant commercial potential in the medical device industry, particularly in the field of cardiac electrophysiology. The system could be marketed to hospitals and medical centers, providing a more accurate and efficient method for treating cardiac arrythmias.
