Lumen Reinforcement Embedment Anchoring Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures for anchoring medical devices in biological lumens are complex and risky, often causing tissue trauma and device migration due to pushing or pulling forces within the lumen.
Innovation Solution
A method of reinforcing the tissue wall by embedding a reinforcement material or structure, such as a wire coil or mesh, using an embedment device that applies outward force to secure the anchor device, preventing migration and enhancing anchoring stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hooks are used to puncture through the wall of the lumen for anchoring, then the device can be anchored, but the procedure becomes more complicated and presents higher risk of tissue trauma and negative outcomes
Solution Approach 1:
The patent introduces a reinforcement material as an intermediary element that is embedded within the tissue wall to provide anchoring support. This mediator material allows the anchoring device to be secured without requiring complex hook puncture procedures, thereby reducing surgical complexity while maintaining anchoring reliability.
Solution Approach 2:
The reinforcement material is embedded into the tissue wall in advance to create a prepared anchoring structure. This preliminary action of embedding the reinforcement material before device implantation allows for simpler, less traumatic anchoring procedures while ensuring reliable device fixation.
2Reliability
If hooks are used for internal anchoring, then the device can be secured, but the procedure presents higher risk of tissue trauma
Solution Approach 1:
The reinforcement material serves as a mediator that distributes anchoring forces throughout the tissue wall, eliminating the need for traumatic hook punctures. This intermediary material provides a trauma-free method of securing devices while maintaining anchoring reliability.
Solution Approach 2:
The patent changes the anchoring mechanism from sharp, localized hook punctures to distributed embedding of reinforcement material. This parameter change in the anchoring approach transforms the interaction with tissue from traumatic to gentle, reducing tissue damage while ensuring secure device fixation.
3Reliability
If outwardly directed force is applied to embed the reinforcement material, then anchoring stability is improved, but the risk of the body migrating to exterior side increases
Solution Approach 1:
The reinforcement material is strategically positioned at specific locations within the tissue wall where it provides maximum anchoring benefit. By concentrating the reinforcement at local key points rather than uniformly throughout, the system achieves high anchoring stability while minimizing migration risk through precise spatial placement.
Solution Approach 2:
The system combines the reinforcement material with the tissue wall to create a composite structure. This composite approach integrates the anchoring function into the tissue itself, providing stable anchoring while the integrated nature prevents migration of the reinforcement body to the exterior.
4Force
If the cross-section dimension of the embedment device body is made greater than the lumen, then outward force is applied to embed, but the device may migrate to exterior side
Solution Approach 1:
The embedment device applies outward force locally at the tissue wall interface rather than uniformly throughout the entire device. This localized force application enables effective embedding while the overall device geometry and material properties prevent migration to the exterior side.
Solution Approach 2:
The embedment device is designed with dynamic characteristics that allow it to expand sufficiently to apply embedding force during installation, then stabilize in the embedded state. The device transitions from a high-force application state during embedding to a stable, migration-prevented state once embedded, managing the contradiction between force application and position stability.

AI summary
A tissue wall of a biological lumen may be reinforced by embedding a material or structure into the tissue wall. The reinforcement material or structure may embed by application of outwardly directed force along an interior side of the tissue wall, threading, or injection. The reinforcement material or structure may act as an embedded scaffold that limits expansion or contraction of the tissue wall to pushing or pulling forces. An anchor device, such as a medical device, may anchor to the reinforced portion of the tissue wall.
