AI Technical Summary

Technical Problem

The lack of efficient embolization tools specifically designed for mouse middle cerebral artery embolism-reperfusion models in the current technology leads to vascular damage and difficulty in embolization during the embolization process, affecting experimental efficiency and model success rate.

Method used

A tool comprising a guide tube, guidewire, balloon, inflation tube, and suction tube has been designed. Through guidewire guidance, balloon expansion, and clamp positioning mechanism, the tool is ensured to move stably and be precisely positioned within the blood vessel, avoiding vascular damage. Furthermore, a sealing component is used to prevent gas leakage from affecting operational stability.

Benefits of technology

It improved the stability and accuracy of thrombectomy, reduced the risk of vascular injury, and increased experimental efficiency and model success rate.

Abstract

This invention discloses a tool for facilitating embolization in a mouse middle cerebral artery embolism-reperfusion model, relating to the field of medical device technology. It includes a guide tube with a guidewire fixedly connected inside. A balloon is located on one side of the guidewire, and a support is provided on the outer surface of the balloon. One side of the balloon is fixedly connected to one side of the guide tube. An inflation tube is fixedly connected to the side of the guide tube away from the balloon, and an suction tube is fixedly connected to the opposite side of the guide tube. This invention, using the above structure, provides stable guidance for the tool's movement within the blood vessel through the cooperation of the guide tube and guidewire, avoiding unnecessary contact and damage to the vessel wall due to tool deviation or shaking. The balloon can be inflated through the inflation tube, providing a suitable channel for the embolus to pass through, effectively solving the problem of difficult embolus passage and reducing the risk of blood vessel rupture.
