Product Benefits

The WEB® Embolization System is first-in-class intrasaccular technology offering a single-device treatment alternative to endovascular coils and complex stenting procedures. The intrasaccular embolization system minimizes the need for a dual antiplatelet regimen required of intraluminal therapies.

  • Proprietary Microbraid technology bridges the aneurysm neck to create an optimal surface for aneurysm healing, allowing the WEB device to provide complete, long lasting treatment of wide-neck bifurcation aneurysms with a single device.

  • The low-profile delivery system and extensive range of device size options offers broad versatility for treating a wide range of ruptured and unruptured aneurysms.

  • The WEB Embolization System is highly effective, demonstrating 82% adequate occlusion and 98% occlusion stability at 1 year1
