Woven EndoBridge (WEB) devices used in the US WEB-IT Study. Woven EndoBridge (WEB) devices used in the US WEB-IT Study. Three WEB devices were used: Double Layer (DL), Single Layer (SL), and Single Layer Sphere (SLS). The WEB DL EV is a mesh sphere composed of two layers of braided nitinol/platinum wires. The inner and outer layers of braid are joined by proximal, middle, and distal platinum/iridium markers. The WEB SL EV and WEB SLS EV models are composed of single layers of braided nitinol. The braids are joined at the proximal and distal ends of the device by radiopaque platinum/iridium markers. David Fiorella et al.
