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 adapts textile products, such as vascular prostheses, for use in specific, narrow markets or unique operational environments, including high-security needs, disaster relief, and extreme weather conditions.

Background and Problem Solved

The original patent disclosed textile products with selectively applied sealing layers or coatings. However, these products may not be suitable for use in specialized environments, where specific properties, such as enhanced durability, water resistance, or adaptability to extreme temperatures, are required. The new inventive concept addresses these limitations by providing textile products tailored to meet the demands of these unique environments.

Detailed Description of the Inventive Concept

The inventive concept comprises textile products, such as vascular prostheses, having selectively applied sealing layers or coatings adapted for use in specific, narrow markets or unique operational environments. For example, in disaster relief applications, the sealing layer or coating may be designed to withstand extreme weather conditions, such as high winds, heavy rainfall, or earthquakes. In high-security environments, the sealing layer or coating may be formulated to provide enhanced durability and resistance to tampering or unauthorized access. The inventive concept also encompasses methods of manufacturing, kits of parts, and methods of implanting these textile products in patients.

Novelty and Inventive Step

The new inventive concept is novel and non-obvious compared to the original patent, as it specifically addresses the needs of specialized environments, which were not considered in the original patent. The adaptation of the textile products to these unique environments, including the development of new sealing layers or coatings, represents an inventive step beyond the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include textile products adapted for use in other specialized environments, such as space exploration, extreme cold or heat, or high-altitude environments. Variations of the inventive concept could also include the use of different materials, such as nanomaterials or biodegradable materials, to create the textile products and sealing layers or coatings.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including healthcare, disaster relief, and security. The market for these specialized textile products is expected to grow as the demand for adaptable, durable, and high-performance materials increases in these industries.
