Flow Diversion Device In 2011, the Food and Drug Administration (FDA) approved a new endovascular device called the Pipelineā„¢ Embolization Device (PED). The PED is a flexible mesh tube made of platinum and nickel-cobalt alloy. Using an endovascular approach like Pipelineā„¢ Embokization Devie (PED) that used in coiling (via a catheter in an artery in the groin), the doctor places the device in the artery from which the aneurysm protrudes (the parent artery), covering the neck of the aneurysm. The device directs blood flow past the aneurysm, which causes clotting and prevents it from expanding or rupturing. This may also cause the aneurysm to shrink over time. The PED can be useful for the treatment of very large or wide-necked aneurysms, which often cannot be effectively treated with coiling. Investigations are currently under way at many medical centers to determine whether the PED may also be safe and effective to use in other types of aneurysms. 22
