Magnetic Bioabsorbable Ventral Hernia Closure Without Mesh
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for closing ventral abdominal hernias often result in complications such as incisional hernias, fascial dehiscence, and primary or recurrent hernias, and require mesh reinforcement, which can lead to long-term complications and risks to underlying viscera.
Innovation Solution
The use of bioabsorbable tissue anchors with magnetic distraction and adjustable connecting members to gradually restore abdominal wall edges to their normal position, avoiding mesh and other intraperitoneal components, and allowing for easy disengagement if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mesh reinforcement is used to prevent hernia recurrence, then the strength and reliability of the closure is improved, but the risk of long-term complications and harm to underlying viscera increases
Solution Approach 1:
The patent removes mesh and other intraperitoneal components from the closure system, extracting the harmful element while maintaining closure reliability through alternative means (sutures and external support)
Solution Approach 2:
The patent introduces an external support device that acts as an intermediary, providing reinforcement from outside the abdomen rather than placing foreign material directly against the viscera, thus maintaining strength while reducing harm
2Productivity
If high tension closure is used to close the abdominal wall, then the productivity of the surgical procedure is improved, but the risk of fascial dehiscence and hernia formation increases
Solution Approach 1:
The patent applies progressive tensioning over time through adjustable sutures and external support, performing the tensioning action gradually rather than all at once, allowing tissue adaptation while maintaining closure integrity
Solution Approach 2:
The patent transforms the static high-tension closure into a dynamic system with adjustable tensioning mechanisms that can be modified over time to match tissue healing and adaptation
3Shape
If component separation is performed to normalize abdominal wall anatomy, then the anatomical restoration is improved, but the complexity of the surgical procedure increases
Solution Approach 1:
The patent divides the abdominal wall into segments that can be independently positioned and secured, allowing anatomical restoration through stepwise approximation rather than complex component separation
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
This method effectively normalizes abdominal wall anatomy without high tension closure or mesh reinforcement, reducing the risk of complications and maintaining tissue health during healing.
Implementation Method 1
The components may include magnetic components that attract one another across the tissue

AI summary
A combined magnetic and bioabsorbable device for ventral hernia closure and/or tension distribution for maintenance of tissue apposition for healing, while avoiding a long-term footprint of foreign material and precluding materials spanning the interior layer of the abdominal closure where risk to visceral structures exists.
