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. 11,857,403.

Summary of the Inventive Concept

An advanced segmented skirted surgical mesh designed to enhance the repair of soft tissue defects, offering improved stability, reduced tissue irritation, and increased efficiency in surgical procedures.

Background and Problem Solved

The original segmented skirted surgical mesh patent, while effective, has limitations in terms of stability, tissue compatibility, and deployment complexity. The new inventive concept addresses these limitations by introducing reinforced central zones, bio-absorbable materials, built-in tensioning systems, and hydrophilic coatings to improve the overall performance and safety of the mesh.

Detailed Description of the Inventive Concept

The enhanced segmented skirted surgical mesh comprises a base layer with a reinforced central zone, providing increased stability and reduced tissue irritation. The mesh features a segmented skirt secured to the base layer only at or adjacent to the outer edge, allowing for improved conformability to the defect's geometry. Additionally, the mesh may incorporate bio-absorbable materials, built-in tensioning systems, or hydrophilic coatings to facilitate tissue integration, reduce inflammation, and enhance the overall repair process. The mesh can be deployed using a specialized tool, ensuring accurate placement and minimizing surgical complications.

Novelty and Inventive Step

The new claims introduce a reinforced central zone, bio-absorbable materials, built-in tensioning systems, and hydrophilic coatings, which are not present in the original patent. These novel features provide a significant improvement over the prior art, offering enhanced stability, reduced tissue irritation, and increased efficiency in surgical procedures.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include variations in the mesh material, geometry, and deployment mechanisms. For example, the mesh could be designed with adjustable tensioning systems, or incorporate sensors to monitor tissue integration. Additionally, the mesh could be adapted for use in different surgical procedures, such as hernia repair or tissue reconstruction.

Potential Commercial Applications and Market

The enhanced segmented skirted surgical mesh has significant commercial potential in the medical device industry, particularly in the areas of soft tissue defect repair and surgical mesh technology. The target market includes hospitals, surgical centers, and medical device manufacturers, with potential applications in hernia repair, abdominal wall reconstruction, and other soft tissue defect repair procedures.
