Abstract
This is a device for bridging the neck of a wide-necked or narrow-necked aneurysm in the vasculature. In general, it is a device used to stabilize aneurysms found in the vasculature by at least partially closing the opening to that aneurysm with consequent limiting of the amount of blood flowing into and out of the chamber. The device is generally made of a metallic or polymeric sheet and is of a shape which may be deployed using a catheter. The device typically has three major components: the central closure area, the centrifugal stabilizers, and the axial stabilizers. The device is intended to be a permanent implant and may be used with or without occlusive devices and materials placed inside the aneurysm volume.
