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. 11,857,699.

Summary of the Inventive Concept

This inventive concept envisions next-generation vascular prostheses with advanced features such as real-time porosity control, self-healing coatings, and 3D printing-based manufacturing. These innovations enable more effective and durable prostheses, improving patient outcomes and reducing healthcare costs.

Background and Problem Solved

The original patent disclosed textile products with selectively applied sealing layers or coatings, but these designs have limitations in terms of adaptability, durability, and manufacturing complexity. The new inventive concept addresses these limitations by introducing dynamic porosity control, self-healing coatings, and 3D printing-based manufacturing, enabling more advanced and effective vascular prostheses.

Detailed Description of the Inventive Concept

The new inventive concept comprises several key components: 1) a sensor for monitoring fluid flow through the prosthesis, 2) a control unit for adjusting the porosity of the prosthesis in response to changes in fluid flow, 3) a self-healing coating that can repair damage in response to environmental changes, and 4) a 3D printing-based manufacturing process for creating complex prosthesis geometries. These components enable the prosthesis to adapt to changing physiological conditions, reducing the risk of complications and improving patient outcomes.

Novelty and Inventive Step

The new claims introduce several novel features, including real-time porosity control, self-healing coatings, and 3D printing-based manufacturing. These innovations represent a significant departure from the original patent, which did not contemplate such advanced features. The inventive step lies in the combination of these features, which enables more effective, durable, and adaptable vascular prostheses.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different sensor types, control unit algorithms, or self-healing coating materials. Variations could also include the application of this technology to other types of prostheses or medical devices, such as cardiac assist devices or ventricular assist devices.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in the medical device industry, particularly in the areas of vascular prostheses, cardiac assist devices, and ventricular assist devices. The market for these devices is expected to grow significantly in the coming years, driven by an aging population and increasing demand for advanced medical technologies.
