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

This inventive concept discloses a novel prosthetic heart valve with integrated sensors for real-time monitoring of fluid flow and pressure, advanced self-lubricating materials for enhanced durability, and a bio-absorbable outer skirt for improved tissue integration.

Background and Problem Solved

The original prosthetic heart valve patent has limitations in terms of durability, tissue integration, and real-time monitoring. The new inventive concept addresses these limitations by incorporating advanced materials and sensors, enhancing the overall performance and lifespan of the valve.

Detailed Description of the Inventive Concept

The prosthetic heart valve comprises an annular frame with an integrated sensor for monitoring fluid flow and pressure within the valve. The sensor is embedded within the perivalvular sealing means and communicates with an external device for real-time monitoring. The leaflet structure is made of a self-lubricating material, reducing friction and wear, and enhancing the valve's durability. The outer skirt is bio-absorbable, allowing for improved tissue ingrowth and integration with the surrounding anatomy. The valve is deployable via a delivery catheter with a retractable sheath, providing precise control of valve expansion.

Novelty and Inventive Step

The new claims introduce novel features such as integrated sensors, self-lubricating materials, and bio-absorbable outer skirts, which are not present in the original patent. These features provide a significant improvement over the existing prosthetic heart valve design, addressing the limitations of durability, tissue integration, and real-time monitoring.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the type of sensor used, incorporating additional features such as anti-calcification treatments, or using different materials for the leaflet structure and outer skirt. These variations could provide further enhancements to the valve's performance and lifespan.

Potential Commercial Applications and Market

The enhanced prosthetic heart valve has significant commercial potential in the medical device industry, particularly in the areas of cardiovascular disease treatment and replacement therapy. The target market includes hospitals, medical research institutions, and patients requiring prosthetic heart valve implantation.
