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. 11,857,411.

Summary of the Inventive Concept

An improved prosthetic heart valve with novel features that enhance its performance, durability, and implantation procedure, addressing the limitations of existing prosthetic heart valves.

Background and Problem Solved

The original patent disclosed a prosthetic heart valve with an annular frame and a leaflet structure. However, the existing design has limitations, such as the need for precise suture placement, risk of calcification, and potential for turbulence. The new inventive concept addresses these limitations by introducing an adjustable suture system, anti-calcification coating, and novel leaflet geometry.

Detailed Description of the Inventive Concept

The enhanced prosthetic heart valve comprises an annular frame with an inflow end and an outflow end, radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration. The leaflet structure is positioned within the frame and secured thereto with a novel, adjustable suture system, allowing for post-implantation adjustments to optimize valve performance. Additionally, the leaflet structure may be treated with an anti-calcification coating to reduce calcification and improve durability. Alternatively, the leaflet structure may be designed with a novel, asymmetrical leaflet geometry that improves blood flow and reduces turbulence. The valve may be delivered using a novel, expandable sheath that facilitates smooth, low-friction delivery to a target site within a patient's heart.

Novelty and Inventive Step

The new claims introduce novel features that are not obvious from the original patent, including the adjustable suture system, anti-calcification coating, and novel leaflet geometry. These features provide significant improvements over the existing design, enhancing the valve's performance, durability, and implantation procedure.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include different materials for the leaflet structure, varying thicknesses for the anti-calcification coating, or modified geometries for the leaflet structure. Additionally, the valve may be designed for use in different anatomical locations or for pediatric applications.

Potential Commercial Applications and Market

The enhanced prosthetic heart valve has significant commercial potential in the cardiovascular medical device industry, offering improved performance, durability, and implantation procedure. The target market includes cardiologists, cardiothoracic surgeons, and medical device companies focused on heart valve replacement and repair.
