Multi-Section Aneurysm Coil for Fast Stable Vascular Occlusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implant devices for treating vascular aneurysms and other anatomical conditions face challenges in accurate and stable placement, requiring improved methods for quick and reliable occlusion.
Innovation Solution
A wire implant with multiple sections of varying stiffnesses is designed, allowing for rapid deployment and secure anchoring at the treatment site, with a stiffer first section securing the implant and a softer section packing into the vessel to occupy the aneurysm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple coils are used to treat an aneurysm, then the treatment can be performed with different functional sections, but the treatment time increases significantly
Solution Approach 1:
The patent combines multiple coils with different functional properties (framing coil, filling coils, finishing coil) into a single multi-sectional wire implant. Each section of the wire is configured to perform a specific function that would traditionally require a separate coil, thereby merging multiple devices into one unified implant that can treat aneurysms more efficiently in a single deployment procedure.
Solution Approach 2:
The wire implant is designed with multi-functionality, where a single device performs multiple roles: the first section acts as a framing coil to provide structural support, the second section functions as filling coils to occlude the aneurysm, and the third section serves as a finishing coil to refine the treatment. This universal design eliminates the need for multiple separate coils and reduces procedural time.
2Loss of time
If a single wire implant is used to treat an aneurysm, then the treatment time is reduced, but the implant must perform multiple functions that traditionally required separate devices
Solution Approach 1:
The wire implant is segmented into multiple distinct sections, each with specific functional characteristics. The first section is configured for framing with appropriate stiffness and geometry, the second section is designed for filling with different mechanical properties, and the third section is structured for finishing. This segmentation allows each part to perform its designated function while maintaining the overall simplicity of a single-wire deployment system.
Solution Approach 2:
Different sections of the wire implant possess locally optimized properties tailored to their specific functions. The framing section has structural characteristics suited for providing scaffolding, the filling section has properties optimized for packing and occlusion, and the finishing section has features designed for precise placement and refinement. This local quality differentiation enables the single implant to perform multiple functions effectively.

AI summary
An implant for vascular treatment may include a wire having three or more sections, with adjacent sections having different stiffnesses and/or other properties to facilitate treating an aneurysm with a single instance of the wire. As compared to treating aneurysms using multiple coils, the wire having three or more sections may reduce the time required for treatment of the aneurysm.
