Endovascular stents, essential in treating vascular situations, are available in numerous designs, with slotted tube and woven configurations being two distinguished varieties. 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 develop radially and conform to the vessel wall. A woven stent, conversely, is constructed by braiding a number of nitinol wires collectively. The interwoven construction types a mesh-like cylinder able to radial growth.
The selection between these stent designs typically will depend on the precise scientific utility. Slotted tube stents are sometimes favored for his or her better radial drive, which gives robust help 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 contemplate 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 situations like arterial stenosis and aneurysms.
