Minimally occlusive flow disruptor stent for bridging aneurysm necks
First Claim
1. An aneurysm closure device deliverable through the vasculature comprising a single-piece sheet having a generally central closure region sized to cover at least most of an opening in a selected vascular aneurysm, at least two circumferential struts extending in generally opposite directions from said closure region, and at least two longitudinal struts extending in generally opposite directions from said closure region, generally orthogonal to said circumferential struts, and together of a length sufficient to stabilize said aneurysm closure device from movement when positioned to cover said at least most of an opening in a vascular aneurysm in cooperation with said circumferential struts.

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.
