Single-Layer Hernia Patch With Peripheral Locating Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hernia repair patch implants for open ventral hernia repairs face challenges such as difficulty in handling, poor visibility during mesh handling and fixation, and the need for dual or multiple layers, which complicate the procedure and increase foreign body mass, making them expensive and complex to manufacture.
Innovation Solution
The development of novel tissue repair patches with a substantially flat or planar base member, featuring a closure member and a locating structure, such as an engagement ring, that allows for single-layer mesh implantation and secure fixation using a single or multiple crown technique, facilitating easier placement and reduced foreign material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual or multiple layers of mesh are used to provide affixation capability, then the mesh can be secured to the abdominal wall, but the foreign body mass increases and manufacturing complexity increases
Solution Approach 1:
The patent combines the mesh body and affixation layer into a single integrated structure. The affixation layer is formed as part of the same continuous piece of prosthetic material as the mesh body, eliminating the need for separate layers while maintaining both reinforcement and fixation functions. This is achieved by forming the affixation layer as a peripheral extension of the mesh with appropriate mechanical properties for tissue engagement.
Solution Approach 2:
The single-layer mesh is designed to perform multiple functions simultaneously: providing structural reinforcement of the abdominal wall, enabling secure fixation through its peripheral affixation layer, and facilitating surgical handling. The affixation layer itself serves dual purposes as both a securing mechanism and a handling feature during implantation.

3Ease of operation
If conventional mesh implants without locating structures are used, then the mesh can be implanted, but visibility during mesh handling and fixation is poor
Solution Approach 1:
The patent incorporates visual indicators such as colored dyes or pigments into the affixation layer or peripheral regions of the mesh. These color changes or variations allow surgeons to easily distinguish the edges and orientation of the mesh during implantation, improving visibility and handling without affecting the functional properties of the prosthetic material.
