Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vascular occlusion devices require multiple coils for effective occlusion, leading to increased time, cost, and risk of coil migration during medical procedures.
Innovation Solution
A vascular occlusion device comprising a hub with anchoring struts and a central strut, along with an extracellular matrix material, which is deployed through a catheter to engage and occlude the body vessel, reducing the need for multiple coils and minimizing migration risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple coils are used to occlude a body vessel, then effective occlusion of fluid flow is achieved, but procedural time and cost increase
Solution Approach 1:
The patent combines multiple coil functions into a single integrated occlusion device. The device includes a framework with multiple arms that can be deployed in one procedure, eliminating the need to pack and deploy multiple separate coils. This merging approach achieves effective occlusion while reducing procedural time and complexity.
2Reliability
If multiple coils are packed within each other, then effective cross sectional occlusion is achieved, but device complexity increases
Solution Approach 1:
The occlusion device is segmented into multiple independent arms or struts that can be deployed separately from a single framework. Each arm can be positioned and secured independently, providing effective occlusion without requiring complex packing of multiple coils. The segmented design simplifies deployment while maintaining occlusion effectiveness.
3Reliability
If multiple coils are deployed, then sufficient occlusion is achieved, but risk of coil migration increases
Solution Approach 1:
The device incorporates anchoring features such as hooks, bars, or other securing elements that are deployed beforehand to prevent migration. These anchoring structures are integrated into the framework and positioned to engage with the vessel wall before the occlusion material is deployed, thereby preventing coil migration while maintaining occlusion effectiveness.

AI summary
A vascular occlusion device for occluding a body vessel is disclosed. The device comprises a hub having proximal and distal ends and a plurality of anchoring struts. Each anchoring strut has a first end and a second end. The first ends are connected together at the hub. Each of the second ends extends freely from the first end to engage the body vessel for anchoring the device therein. The device further comprises a central strut attached to the proximal end of the hub. The device further comprises a proximal and distal members and an extracellular matrix material. The proximal and distal members are slidibly disposed about the central strut. The extracellular matrix material is disposed about the central strut between the proximal and distal members.
