Single Plane Tissue Repair Patch with Bioabsorbable Barrier
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.
Innovation Solution
A novel tissue repair patch with a substantially flat or planar base member, featuring a polymeric layer on at least one side and a bioabsorbable adhesion barrier member, which can be secured using a single or multiple crown technique without requiring a mesh anchoring layer, facilitating easier implantation and fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual or multiple layers of mesh are used to provide mesh anchoring and tissue separation functions, then the reliability of hernia repair is improved, but the device complexity and foreign body mass increase
Solution Approach 1:
The patent combines multiple functions (mesh anchoring, tissue separation, adhesion prevention) into a single mesh layer by integrating polymeric coatings and bioabsorbable adhesion barrier members directly onto the mesh structure, eliminating the need for dual or multiple separate mesh layers while maintaining repair reliability
Solution Approach 2:
The single mesh layer is designed to perform multiple functions simultaneously: providing structural support for hernia repair, anchoring to tissue through polymeric coatings, separating viscera from the prosthetic layer, and preventing adhesion formation, thereby replacing what traditionally required multiple specialized layers
2Reliability
If dual or multiple layers of mesh are used to provide mesh anchoring and tissue separation functions, then the reliability of hernia repair is improved, but the foreign body mass increases
Solution Approach 1:
The patent combines multiple functions (mesh anchoring, tissue separation, adhesion prevention) into a single mesh layer by integrating polymeric coatings and bioabsorbable adhesion barrier members directly onto the mesh structure, eliminating the need for dual or multiple separate mesh layers while maintaining repair reliability
Solution Approach 2:
The bioabsorbable adhesion barrier member is designed to degrade over time after serving its protective function, converting from a permanent foreign body into a temporary protective layer that is naturally absorbed by the body, thereby reducing long-term foreign body mass
3Reliability
If conventional mesh handling and fixation procedures are used, then the repair function is achieved, but the ease of operation deteriorates due to poor visibility and handling difficulty
Solution Approach 1:
The polymeric coating on the mesh can be designed with specific optical properties or color characteristics that enhance visibility during surgery, allowing surgeons to better see and manipulate the mesh material under various lighting conditions and through tissue layers
4Reliability
If additional treatment layers are added to separate viscera from prosthetic layer, then adhesion prevention is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent combines the adhesion prevention function with the mesh structure itself by integrating bioabsorbable adhesion barrier members directly onto the mesh during manufacturing, creating a single combined component that prevents adhesions without requiring separate additional treatment layers
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The novel patch design enhances the ease of handling and fixation during open hernia repair procedures, reduces foreign body mass, and simplifies the manufacturing process, while providing effective tissue integration and minimizing post-operative adhesions.
Implementation Method 1
a bioabsorbable adhesion barrier member attached about its periphery to the periphery of the bottom side of the base member to form a pocket accessible through the opening
Data Source
AI summary
A novel single plane tissue repair device such as a patch is disclosed. The device has a base member with an opening therethrough, and a closure member associated with the opening. The mesh has a biaborbable polymeric adhesion barrier attached to the bottom side of the base member about its periphery to form a pocket that is accessible through the opening. The mesh may be used in open surgical procedures for hernia repairs and other repairs of body wall defects.
