AI Technical Summary
Traditional ureteral stents have problems with reflux and displacement, especially in patients with ureteral stricture. Existing metal stents cannot simultaneously meet the requirements for axial and radial support forces and are prone to wear and breakage.
A braided ureteral stent with anti-reflux and anti-migration is designed. The stent body is composed of multiple metal wire braided units, including a first anti-migration section, a radial support section, an anti-reflux section, and a second anti-migration section. Each metal wire braided unit is fixed by locking components. A funnel-shaped structure and metal wire anchors are set to enhance the support and anti-reflux effect.
It significantly enhances the axial and radial support capacity of the support, reduces the risk of displacement, improves the anti-backflow effect, and has a simple structure, low cost, and can be adapted to different lengths and diameters.
