Arcuate Filament Platform Insert for Endovascular Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endovascular filament bowls struggle to securely store and manage multiple filaments without entanglement, leading to prolonged surgical procedures and potential contamination risks due to the stiffness of filaments causing them to uncoil and press against the bowl walls, resulting in spilling.
Innovation Solution
A filament platform insert with alternating stages and recesses forming arcuate channels and raceways, allowing for secure storage and easy extraction of individual filaments, preventing entanglement and facilitating smooth handling during surgical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple endovascular filaments are stored in a single conventional bowl, then the container can hold multiple filaments, but the filaments become entangled with one another
Solution Approach 1:
The bowl is divided into multiple separate compartments, each capable of holding a single filament. This segmentation prevents filaments from contacting each other and becoming entangled, while still allowing multiple filaments to be stored in the same bowl container.
Solution Approach 2:
Each compartment is designed with specific local characteristics including curved surfaces that guide filament placement, barriers that prevent rising, and optimized geometries that accommodate the stiffness of individual filaments. These localized features ensure each filament is retained independently without interference from others.
2Ease of operation
If endovascular filaments are stored in a conventional bowl, then they can be readily accessed, but the stiffness of filaments causes them to uncoil and press against the bowl wall, resulting in spilling
Solution Approach 1:
Barriers are positioned within each compartment at strategic locations to prevent filaments from rising along the wall and spilling over the rim. These barriers create preliminary opposition to the uncoiling force, containing the filaments within the compartment boundaries while maintaining accessibility.
Solution Approach 2:
The compartments utilize curved surfaces and arcuate geometries that conform to the natural shape of coiled filaments. The curved bottom and wall surfaces guide filaments into stable positions, reducing the tendency to press against rigid flat surfaces and spill.
3Reliability
If conventional bowls with barriers are used to prevent filament spilling, then filament containment is improved, but the complexity of the bowl structure increases
Solution Approach 1:
Rather than adding complex barriers to a single large compartment, the solution segments the bowl into multiple simpler compartments. Each compartment has its own simple barrier structure, but the overall system achieves better containment with less total complexity by distributing the containment function across separate zones.
Solution Approach 2:
Each compartment serves multiple functions simultaneously: it contains a single filament, provides barriers to prevent spilling, guides filament placement through curved surfaces, and maintains accessibility. This multi-functionality reduces the need for additional specialized components.

AI summary
A filament platform insert for insertion into a bowl includes a plurality protruding stages and a plurality of recesses that are each formed in arcuate shapes to form a plurality of arcuate filament channels. An access channel extending along the platform insert, between a top and bottom, and between a rear and front, provides access for insertion of a finger or tool for manipulating an endovascular filament stored in the filament channel. The platform insert is dimensioned such that alignment of multiple such platforms will form filament raceways within a bowl for the coiled reception and storage of multiple endovascular filaments, with each filament reliably isolated from one another. In an alternative configuration, an endovascular filament bowl may be made to have the filament platform as a monolithic component thereof.
