Surpass NeuroEndoGraft (SJN1301): Device and the State in Japan

The flow diverter was developed with great expectations as a therapeutic device for intracranial aneurysms that have been difficult to treat to date. Placed in the parent artery of an intracranial aneurysm, it covers its neck, promotes complete occlusion, and prevents rupture of the aneurysm by reducing the blood flow to the aneurysm, inducing its thrombosation, serving as a scaffold for newly formed intimal tissue covering the neck of the aneurysm, and separating the aneurysm from the circulation of the parent artery.
