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. 11,857,413.

Summary of the Inventive Concept

An advanced prosthetic heart valve system featuring variable stiffness zones, protective coatings, integrated sensors, and modular designs to improve durability, functionality, and customization for individual patient needs.

Background and Problem Solved

The original patent disclosed a stented prosthetic heart valve with methods of use. However, the existing design has limitations in accommodating diverse anatomical locations, ensuring valve durability, and facilitating real-time performance monitoring. The new inventive concept addresses these limitations by introducing adaptive features that enhance the overall performance and adaptability of the prosthetic heart valve system.

Detailed Description of the Inventive Concept

The enhanced prosthetic heart valve system comprises a stent frame with variable stiffness zones achieved through differential strut thickness or material selection, allowing for optimal deployment in various anatomical locations. A protective coating is incorporated on the valve structure to reduce wear and tear from repeated valve closure, thereby enhancing valve durability. An integrated sensor is configured to detect changes in valve function and provide real-time feedback to physicians. Additionally, a novel catheter design with an adjustable stiffness section enables smooth navigation through tortuous anatomical pathways. The modular design allows for interchangeable valve structures and stent frames, enabling customization and adaptability to individual patient needs.

Novelty and Inventive Step

The new claims introduce non-obvious improvements over the original patent, including variable stiffness zones, protective coatings, integrated sensors, and modular designs. These features collectively provide a novel and inventive solution that addresses the limitations of the existing prosthetic heart valve system.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different materials or geometries for the variable stiffness zones, incorporating additional sensors or monitoring systems, or developing alternative modular designs. These variations would ensure broad conceptual coverage and adaptability to diverse clinical scenarios.

Potential Commercial Applications and Market

The enhanced prosthetic heart valve system has significant commercial potential in the medical device industry, particularly in the cardiovascular segment. The target market includes hospitals, clinics, and medical centers performing heart valve replacement surgeries, as well as patients requiring prosthetic heart valves. The adaptive features and improved performance of the new inventive concept are expected to drive market adoption and growth.
