Patent attributes
The present invention provides a braided implant with a retractable dual proximal layer and methods for administering the braided implant to treat aneurysms. The implant can include a tubular braid that can be set into a predetermined shape, compressed for delivery through a microcatheter, and implanted in at least one implanted position that is based on the predetermined shape and the geometry of the aneurysm in which the braid is implanted. The implant can also have a retractable dual layer at the proximal end of the device made of the same braid to provide additional coverage at the neck of the aneurysm. The dual layer can be pressed distally into a first implanted portion of the tubular braid, moving the first portion of the tubular braid towards the distal portion of an aneurysm wall so that the implant can partially or completely occlude an aneurysm neck.
