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. 11,857,418.

Summary of the Inventive Concept

The present disclosure introduces a novel system and method for aligning annuloplasty rings with natural fiducials at an annular target, utilizing real-time imaging data to dynamically adjust the alignment process and improve the accuracy of engagement, thereby enhancing the efficiency and effectiveness of annuloplasty procedures.

Background and Problem Solved

The original patent, 'Annuli engagement and reshaping using natural fiducials', introduced a method for aligning annuloplasty rings with natural fiducials present at or near an annular target. However, this approach had limitations, including the potential for inaccurate engagement and inefficient reshaping. The present inventive concept addresses these limitations by incorporating real-time imaging data and adaptive alignment capabilities, ensuring more accurate and efficient annuloplasty procedures.

Detailed Description of the Inventive Concept

The enhanced system comprises an annuloplasty ring, a sensor array for detecting changes in the annular target's geometry, and a real-time imaging module for dynamically adjusting the alignment process. The system utilizes machine learning algorithms to analyze historical data on annular target geometries and predict the optimal alignment configuration for a given patient. Additionally, the system includes micro-anchors for securely fastening the ring to the annulus, designed to minimize tissue damage and promote efficient healing.

Novelty and Inventive Step

The new claims introduce the novel concept of utilizing real-time imaging data and adaptive alignment capabilities to enhance the accuracy and efficiency of annuloplasty procedures. This represents a significant improvement over the original patent, which relied solely on natural fiducials for alignment. The incorporation of machine learning algorithms and micro-anchors further distinguishes the present inventive concept from the prior art.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different imaging modalities, such as ultrasound or MRI, or the incorporation of additional sensors to detect changes in the annular target's geometry. Variations of the system could also include different types of micro-anchors or alternative materials for the annuloplasty ring.

Potential Commercial Applications and Market

The enhanced annuli engagement and reshaping system has significant commercial potential in the medical device industry, particularly in the field of cardiovascular surgery. The system's ability to improve the accuracy and efficiency of annuloplasty procedures could lead to increased adoption and market share, as well as improved patient outcomes.
