Lay abstract The Woven EndoBridge device recently received approval by the US FDA for use in certain types of difficult to treat brain aneurysms. This article is primarily a descriptive and technical article aimed at doctors who use catheter-based techniques to treat problems of the blood vessels. Initial studies show that the device is at least as effective as previously existing methods, though more research needs to be done regarding long-term outcomes.
