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 enhanced prosthetic valve system featuring an expandable frame with improved durability, flexibility, and conformability, designed to reduce the risk of frame fracture, paravalvular leakage, and improve hemodynamic performance.

Background and Problem Solved

The original prosthetic valve patent has limitations in terms of frame durability, flexibility, and conformability, which can lead to frame fracture, paravalvular leakage, and compromised hemodynamic performance. The new inventive concept addresses these limitations by introducing novel frame designs, materials, and manufacturing processes that improve the overall safety and performance of the prosthetic valve system.

Detailed Description of the Inventive Concept

The enhanced prosthetic valve system features an expandable frame comprising a plurality of frame members designed to reduce the risk of frame fracture during deployment. The frame members have a unique geometry that allows for increased flexibility and conformability to the native valve orifice, improving the overall fit and performance of the prosthetic valve. The system also includes leaflets designed to have improved coaptation and reduced leaflet stress, thereby improving the overall durability and longevity of the prosthetic valve system. The novel material or process used in manufacturing the prosthetic valve further enhances frame durability and reduces material fatigue.

Novelty and Inventive Step

The new claims introduce novel frame designs, materials, and manufacturing processes that are not obvious from the original patent. The unique geometry of the frame members, the improved coaptation and reduced leaflet stress, and the novel material or process used in manufacturing the prosthetic valve are all new and non-obvious features that provide significant improvements over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the frame geometry, material, or manufacturing process to further optimize the prosthetic valve's performance and durability. Additional variations could include modifying the leaflet design or incorporating sensors or other features to enhance the prosthetic valve's functionality.

Potential Commercial Applications and Market

The enhanced prosthetic valve system has significant commercial potential in the medical device industry, particularly in the fields of cardiovascular disease treatment and minimally invasive surgical procedures. The improved safety and performance of the prosthetic valve system could lead to increased adoption and market share, as well as opportunities for expansion into new markets and applications.
