This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,263.

Summary of the Inventive Concept

An improved system for personalized atrial fibrillation ablation, providing more precise and effective treatment through advanced 3D modeling, real-time feedback, and adaptive ablation patterns.

Background and Problem Solved

The original patent disclosed a personalized atrial fibrillation ablation device utilizing a 3D model of the patient's heart. However, the device had limitations in accommodating variations in pulmonary vein anatomy and lacked real-time feedback to adjust the ablation process. The new inventive concept addresses these limitations by introducing an adjustable ablation panel and a real-time feedback system.

Detailed Description of the Inventive Concept

The enhanced system comprises a three-dimensional model generator, an ablation catheter custom-designed based on the model, and a real-time feedback system to monitor and adjust the ablation process. The ablation panel is adjustable to accommodate variations in pulmonary vein anatomy, ensuring a more precise and effective treatment. The real-time feedback system includes a sensor array to detect changes in the patient's heart rhythm during ablation and a control unit to adjust the ablation pattern in response to the detected changes.

Novelty and Inventive Step

The new claims introduce the concept of an adjustable ablation panel and a real-time feedback system, which are not present in the original patent. These features provide a more adaptive and effective treatment, making the new inventive concept novel and non-obvious.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of sensors or imaging modalities to generate the 3D model, or incorporating machine learning algorithms to optimize the ablation pattern. Variations could also include using the system for treating other cardiac arrhythmias or integrating it with other medical devices.

Potential Commercial Applications and Market

The enhanced personalized atrial fibrillation ablation system has significant commercial potential in the medical device industry, particularly in the cardiac electrophysiology market. It could be marketed as a premium product for hospitals and clinics, offering improved treatment outcomes and reduced procedure times.
