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. 11,857,412.

Summary of the Inventive Concept

An improved prosthetic valve with an expandable frame, incorporating advanced features such as controlled expansion, real-time performance monitoring, and enhanced tissue integration, providing enhanced safety, efficiency, and effectiveness in transcatheter delivery and implantation procedures.

Background and Problem Solved

The original prosthetic valve with an expandable frame, as described in the original patent, has inherent limitations, including the risk of valve failure, limited tissue integration, and lack of real-time performance monitoring. The new inventive concept addresses these limitations by introducing advanced features that improve the valve's overall performance, safety, and efficiency.

Detailed Description of the Inventive Concept

The enhanced prosthetic valve features an expandable frame comprising interconnected nodes, allowing for controlled expansion and contraction. The valve is designed for transcatheter delivery and implantation, with a retractable sheath catheter facilitating compact delivery and deployment. The valve is equipped with sensors that monitor its performance in real-time, providing valuable feedback to the user. Additionally, the frame is coated with a bio-compatible material that enhances tissue integration and reduces the risk of valve failure.

Novelty and Inventive Step

The new inventive concept introduces a novel combination of features, including controlled expansion, real-time performance monitoring, and enhanced tissue integration, which are not present in the original patent. The inventive step lies in the integration of these advanced features, which provide a significant improvement over the existing prosthetic valve design.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the frame design, such as using different materials or geometries, or incorporating additional features, such as anti-calcification coatings or shape-memory alloy components. Other variations could include different sensor configurations or data analysis algorithms to enhance real-time performance monitoring.

Potential Commercial Applications and Market

The enhanced prosthetic valve with advanced features has significant commercial potential in the medical device industry, particularly in the areas of transcatheter heart valve replacement and minimally invasive cardiac surgery. The target market includes hospitals, clinics, and medical research institutions, with potential for widespread adoption and revenue growth.
