Vascular Implant Anchoring Threads for Telescopic Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vascular implants face issues with secure attachment of distal and proximal sections, leading to potential dislocation, increased diameter, and reduced maneuverability due to stiffeners, necessitating large-caliber catheters.
Innovation Solution
An anchoring system using threads and/or sutures formed from threads, located inside the vascular implant, provides secure fixation points without increasing diameter or stiffness, enhancing maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stiffeners are used to secure attachment of distal and proximal sections, then reliability of attachment is improved, but device diameter increases and maneuverability deteriorates
Solution Approach 1:
The patent uses a flexible membrane structure with integrated anchoring elements instead of rigid stiffeners. The membrane remains thin and flexible, allowing the device to be maneuvered through catheters while the anchoring elements provide secure attachment when deployed in the vascular system.
Solution Approach 2:
The anchoring system is segmented into discrete anchoring elements distributed along the membrane rather than using continuous rigid structures. This segmentation allows flexibility in the overall device while providing localized secure attachment points.
2Reliability
If stiffeners are used to secure attachment of distal and proximal sections, then reliability of attachment is improved, but catheter size must be larger
Solution Approach 1:
The flexible membrane construction allows the device to pass through smaller catheters while maintaining the ability to provide secure attachment in the target vascular location, eliminating the need for large-caliber catheters.
Solution Approach 2:
The anchoring elements are integrated within or attached to the membrane structure in a nested configuration, allowing compact packaging that can be delivered through smaller catheters while expanding functionality at the deployment site.
3Strength
If conventional anchoring methods are used, then attachment strength is improved, but device complexity increases
Solution Approach 1:
The patent combines the anchoring function directly into the membrane structure by integrating anchoring elements during manufacturing. This merging of functions eliminates the need for separate, complex anchoring mechanisms and reduces overall device complexity.
Solution Approach 2:
The anchoring elements are designed to self-deploy and secure attachment automatically upon insertion into the vascular system, eliminating the need for complex manual anchoring procedures or additional complex components.
