Single Plane Tissue Repair Patch with Integrated Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hernia repair patches for open ventral hernia repairs face challenges such as difficulty in handling, poor visibility during mesh handling and fixation, and poor ergonomics, especially during laparoscopic procedures, often requiring dual or multiple layers of mesh that increase foreign body mass and complexity.
Innovation Solution
The development of novel tissue repair patches with a substantially flat or planar base member and a closure member, which can be secured using a single or multiple crown technique without the need for an additional anchoring layer, featuring a polymeric layer on at least one side to prevent adhesions and improve usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual or multiple layers of mesh are used to provide anchoring and prevent adhesions, then reliability of repair is improved, but device complexity and foreign body mass increase
Solution Approach 1:
The patent combines the anchoring function and adhesion prevention function into a single mesh layer. The mesh includes integrated anchoring elements (such as protrusions or fixation structures) that provide secure attachment, while simultaneously incorporating a non-adhesive coating or barrier layer on the tissue-contacting surface. This merging eliminates the need for separate anchoring layers and adhesion barrier layers, reducing overall device complexity and foreign body mass while maintaining repair reliability.
Solution Approach 2:
The single mesh layer is designed to perform multiple functions simultaneously: providing structural reinforcement, enabling secure anchoring to tissue, and preventing adhesion formation. The mesh incorporates both mechanical anchoring features and a non-adhesive surface treatment, allowing one component to fulfill roles that traditionally required multiple separate layers, thereby simplifying the overall device structure.
2Reliability
If additional treatment layers are added to prevent adhesions, then reliability is improved, but ease of operation deteriorates due to increased complexity
Solution Approach 1:
The adhesion prevention function is merged directly into the single mesh layer through surface coating or integrated barrier structures. This eliminates the need for separate adhesion barrier layers that would complicate handling. The mesh maintains a streamlined, single-layer configuration that is easier to manipulate during surgery while still providing reliable adhesion prevention through its integrated non-adhesive surface.
3Device complexity
If single layer mesh is used, then device complexity and foreign body mass are reduced, but reliability may deteriorate due to insufficient anchoring
Solution Approach 1:
The single mesh layer incorporates localized anchoring elements at specific regions where fixation is needed. These anchoring protrusions or fixation structures are strategically positioned on the mesh to provide secure attachment to surrounding tissue. This local concentration of anchoring functionality ensures reliable fixation while maintaining the overall simplicity and single-layer structure of the mesh, avoiding the need for multiple layers.
