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 advanced personalized atrial fibrillation ablation system that incorporates adaptive ostial fitment elements, real-time machine learning optimization, and robotic navigation to improve treatment efficacy and efficiency.

Background and Problem Solved

The original personalized atrial fibrillation ablation device, while innovative, still faces limitations in accommodating variations in pulmonary vein anatomy and ensuring precise ablation patterns. The new inventive concept addresses these limitations by introducing adaptive ostial fitment elements, real-time optimization using machine learning algorithms, and robotic navigation to ensure precise placement and orientation of the ablation elements.

Detailed Description of the Inventive Concept

The enhanced personalized atrial fibrillation ablation system comprises a patient-specific customized ablation catheter with adaptive ostial fitment elements that dynamically adjust to accommodate variations in pulmonary vein anatomy during the ablation procedure. The system also incorporates real-time machine learning algorithms that optimize the ablation pattern using data from the patient's three-dimensional heart model and electroanatomical mapping. Furthermore, the system utilizes a robotic navigation system that integrates real-time imaging data and electroanatomical mapping to ensure precise placement and orientation of the ablation elements. The system may also include a database of three-dimensional heart models and associated ablation patterns, allowing for optimal ablation patterns to be suggested for a patient based on similarities with previously treated patients.

Novelty and Inventive Step

The new claims introduce adaptive ostial fitment elements, real-time machine learning optimization, and robotic navigation, which are not present in the original patent. These innovations provide a significant improvement in treatment efficacy and efficiency, making the new inventive concept novel and non-obvious compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include using different types of adaptive ostial fitment elements, such as shape-memory alloy or inflatable elements. Additionally, the system may be adapted for use in other cardiac arrhythmia treatments, such as ventricular tachycardia or atrial flutter.

Potential Commercial Applications and Market

The enhanced personalized atrial fibrillation ablation system has significant commercial potential in the electrophysiology and cardiology markets, offering improved treatment outcomes and reduced procedure times. The system may be marketed to hospitals, clinics, and medical centers, and may also be used in conjunction with other cardiac arrhythmia treatments.
