Endovascular stents, essential in treating vascular circumstances, are available numerous designs, with slotted tube and woven configurations being two outstanding sorts. A slotted tube stent is usually manufactured from a single piece of nitinol tubing. Exact cuts, or slots, are laser-etched into the tube, creating an outlined sample. This sample permits the stent to broaden radially and conform to the vessel wall. A woven stent, conversely, is constructed by braiding a number of nitinol wires collectively. The interwoven construction varieties a mesh-like cylinder able to radial growth.
The selection between these stent designs usually depends upon the precise scientific software. Slotted tube stents are sometimes favored for his or her larger radial pressure, which supplies sturdy assist to the vessel and resists collapse. Woven stents, resulting from their versatile nature, could also be most well-liked in tortuous or extremely curved vessels. The choice should additionally think about elements like fracture resistance and conformability to the vessel wall. The evolution of stent expertise displays a steady effort to optimize these traits for improved affected person outcomes in treating circumstances like arterial stenosis and aneurysms.
