Wound Closure Meshes with Detachable Tabs for Laparoscopic Incisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wound closure systems, such as EXOFIN FUSION®, are primarily designed for larger incisions and are not optimized for laparoscopic or minimally invasive surgical procedures that involve smaller incisions.
Innovation Solution
A wound closure device and kit that includes self-adhering mesh patches and a liquid skin adhesive, where the mesh patches are held on a release liner with detachable tabs, allowing for easy application and handling over small wounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wound closure system is designed for larger incisions (up to 20-58 cm), then it provides adequate coverage for large wounds, but it is not optimized for smaller incisions used in laparoscopic procedures
Solution Approach 1:
The wound closure device is divided into multiple separate mesh patches, each suitable for different incision sizes. The kit includes several meshes of varying dimensions that can be selected and applied individually to small laparoscopic incisions, rather than using a single large mesh designed for bigger incisions.
2Ease of operation
If mesh patches are held securely to the release liner for storage and handling, then the device maintains stability during storage, but the mesh patches are difficult to remove and apply to the wound
Solution Approach 1:
Tabs are pre-attached to the release liner in specific positions and configurations before the mesh patches are applied to the wound. These tabs remain attached to the release liner during storage and handling, providing stability, and are removed only when needed for mesh application, making the removal process easier and more controlled.
3Strength
If the wound closure system provides a strong seal for larger wounds, then it ensures adequate closure strength, but it is not optimized for the specific requirements of small laparoscopic incisions
Solution Approach 1:
The device provides different mesh patch sizes and configurations optimized for specific incision types. Small laparoscopic incisions receive appropriately sized meshes with dimensions and structural properties tailored to those specific wound characteristics, rather than using a one-size-fits-all approach designed for larger incisions.
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 solution provides a strong, watertight seal for small wounds, allowing patients to resume normal activities quickly, while preventing skin gaps and promoting healing.
Implementation Method 1
the liquid, topical skin adhesive is applied over the exposed surface of the mesh patch and allowed to polymerize, which may take in some uses approximately 45-60 seconds
Implementation Method 2
The mesh patches are coated on a single side with a pressure-sensitive adhesive (PSA), and in use, the PSA-coated side directly contacts the skin to temporarily adhere the mesh patch(es) to the skin

AI summary
Wound closure devices and related methods. In one example, a wound closure device includes a release liner and several wound closure meshes held in a removable fashion to the release liner. The release liner includes a main body and several tabs, with the tabs secured in a detachable fashion to the main body. Each wound closure mesh is held in a removable fashion to the main body of the release liner and at least one of the tabs, with the tab including a portion that extends outwardly from an outer perimeter of the mesh to which it is held.
