Problems solved by technology

However, when the ends are welded in pairs or when a single wire is folded and welded, there are more welding spots, which will increase the size of the stent in the conveyor when it is compressed, and affect the delivery performance of the stent
And the above-mentioned various designs are relatively complicated
Moreover, the ends of the above-mentioned brackets have no developing design

Abstract

The invention relates to a woven stent. The woven stent is formed by weaving a plurality of wires, and is characterized in that: the wires at the end of the woven stent are divided into a plurality of strands according to the number of the wires of the woven stent, wherein all the wires in each strand of wires are fixed together. By the woven stent, the wires at the end of the woven stent can be effectively prevented from being scattered, and adherence to the wall and infusion performance of the stent are improved.

Description

technical field [0001] The invention relates to the medical field of vascular intervention, in particular, the invention relates to a braided mesh-like stent. Background technique [0002] At present, common cardiovascular and cerebrovascular diseases mainly include arterial stenosis and aneurysm. If these diseases are not treated in time, they may lead to blood vessel blockage and tumor rupture, which will seriously endanger human life. [0003] For the treatment of aneurysms, surgical procedures such as surgical resection or clipping were mainly used in the early stage. With the progress of the times, at present, minimally invasive interventional surgery is mainly used, such as stent closure or coil, liquid embolism and other treatment methods. This kind of method has little trauma to the patient, high safety, and good therapeutic effect, so it has made great progress in technology. At present, the methods used in minimally invasive interventional surgery have their own ...
