Enhanced Textile Products with Bio-Absorbable Sealants and Advanced Manufacturing Techniques
Legal Citation
Summary of the Inventive Concept
This inventive concept improves textile products, such as vascular prostheses, by introducing novel, bio-absorbable sealants and advanced manufacturing techniques, enhancing biocompatibility, reducing inflammation, and increasing efficiency.
Background and Problem Solved
The original patent disclosed textile products with selectively applied sealing layers or coatings, but these products had limitations in terms of biocompatibility and manufacturing efficiency. This new inventive concept addresses these limitations by introducing bio-absorbable materials and advanced manufacturing techniques.
Detailed Description of the Inventive Concept
The new inventive concept comprises textile products with selectively applied sealing layers or coatings made from novel, bio-absorbable materials that enhance biocompatibility and reduce inflammation. The manufacturing process involves applying sealants or coatings to textile substrates using ultrasonic-assisted deposition, increasing uniformity and efficiency. Additionally, the textile tubular walls can have nanostructured surfaces that enhance blood compatibility and reduce thrombogenicity.
Novelty and Inventive Step
The use of bio-absorbable materials, ultrasonic-assisted deposition, and nanostructured surfaces represents a significant departure from the original patent, providing a non-obvious solution to the limitations of the prior art.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include using different bio-absorbable materials, modifying the ultrasonic-assisted deposition process, or incorporating additional features to enhance the textile products' performance. Variations could also include applying the inventive concept to different types of textile products or medical devices.
Potential Commercial Applications and Market
The enhanced textile products with bio-absorbable sealants and advanced manufacturing techniques have significant commercial potential in the medical device industry, particularly in the areas of vascular prostheses, cardiac assist devices, and biological heart valves.
