Advanced Textile Products with Enhanced Biocompatibility and Performance

This inventive concept relates to improved textile products, such as vascular prostheses, with selectively applied sealing layers or coatings that exhibit enhanced biocompatibility, reduced risk of adverse reactions, and improved performance. The novel combination of a hydrophilic polymer and a bioabsorbable material in the sealing layer or coating, along with advanced manufacturing methods and minimally invasive delivery systems, provides a significant advancement in the field of textile products.

The original patent disclosed textile products with selectively applied sealing layers or coatings, but had limitations in terms of biocompatibility, risk of adverse reactions, and manufacturing complexity. This inventive concept addresses these limitations by introducing novel materials, manufacturing methods, and delivery systems that improve the overall performance and safety of the textile products.

The inventive concept comprises a textile product having a selectively applied sealing layer or coating formed from a novel combination of a hydrophilic polymer and a bioabsorbable material. This unique material combination enhances the biocompatibility of the textile product, reducing the risk of adverse reactions and promoting tissue ingrowth. The manufacturing process involves applying a masking agent to the textile substrate, depositing the sealing layer or coating, and removing the masking agent, resulting in a uniform and precise deposition of the sealing layer or coating. Additionally, the inventive concept includes a novel, automated application device that ensures consistent deposition of the sealing layer or coating. The textile product can be used in various applications, including vascular prostheses, and can be implanted using a minimally invasive delivery system that reduces trauma to the patient and promotes faster recovery.

The novel combination of a hydrophilic polymer and a bioabsorbable material in the sealing layer or coating, along with the advanced manufacturing methods and minimally invasive delivery systems, provides a significant inventive step over the original patent. The use of a biodegradable masking agent, novel antimicrobial agents, and automated application devices are also new and non-obvious features that distinguish this inventive concept from the prior art.

Alternative embodiments of the inventive concept could include the use of different hydrophilic polymers or bioabsorbable materials, varying the composition and structure of the sealing layer or coating, or incorporating additional features such as sensors or drug-eluting capabilities. The manufacturing process could also be modified to include additional steps or use different deposition techniques.

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of vascular prostheses, cardiac assist devices, and tissue engineering. The improved biocompatibility, reduced risk of adverse reactions, and enhanced performance of the textile products could lead to increased adoption and market share in these industries.
