Guide Wire-Integrated Stent Structure for Faster Thrombus Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endovascular devices require multiple steps and time-consuming procedures for positioning at the target location, particularly in time-critical treatments like thrombus removal, and often fail to completely remove thrombi without risking further embolization.
Innovation Solution
An endovascular device with a stent structure that is temporarily released in a blood vessel and introduced through a microcatheter, connected to a guide wire extending beyond its distal end, allowing simultaneous advancement and deployment without separate manipulation steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate manipulation steps are used for positioning the endovascular device, then the device can be precisely placed, but the procedure becomes time-consuming and complex
Solution Approach 1:
The patent combines the guide wire and stent structure into a single integrated device. The guide wire serves dual functions: as a positioning guide and as a deployment mechanism for the stent. This eliminates the need for separate manipulation steps where a guide wire would be positioned first, then a separate stent would be deployed, thereby reducing procedure time while maintaining positioning precision through the integrated design.
2Reliability
If multiple separate devices are used for thrombus removal, then the treatment can be thorough, but the procedure becomes more complex and time-consuming
Solution Approach 1:
The patent integrates the stent structure with thrombus removal functionality into a single device. The stent can be deployed to support the vessel wall while simultaneously capturing or compressing thrombi against the vessel wall. This combined function eliminates the need for separate thrombus removal devices, reducing procedural complexity while maintaining effective thrombus removal through the integrated stent-thrombus interaction mechanism.

AI summary
The invention relates to an endovascular device with a stent structure and a guide wire. The stent structure has a substantially cylindrical main portion, and at least one point of connection with a guide wire, wherein the guide wire runs along the periphery of the stent structure and extends distally beyond the stent structure. According to an alternative embodiment, the stent structure connects to a tube through which a guide wire extends distally beyond the stent structure. The device according to the invention permits the simultaneous introduction of guide wire and stent structure into the blood vessel together with a microcatheter without there having to be, in the interim, a change between the guide wire, the microcatheter and the stent structure.
