摘要：Devices and methods are disclosed for placing a barrier across the neck of avascular aneurysm, and specifically across the neck of a cerebrovascular aneurysm. Thebarrier is a stent or neck bridge that completely or partially blocks the flow of blood

into the aneurysm and, further, prevents the migration of embolic coils out of theaneurysm and into the parent vessel. The neck bridge or stent of the present inventioncomprises elements for superior flexibility and stability when placed within the parentvessel. The neck bridge or stent of the present invention is loaded into the catheter byeither being rolled tightly and sheathed or stretched to permit loading into the deliverycatheter in a small, highly flexible configuration that may be advanced through thecerebrovasculature to pathological aneurysms.
