Instructions for use


1. Semi -custom-made
Najuta is a semi-custom-made stent graft having a variety of three-dimensional structures, which enables to provide a suitable stent graft matching with a patient’s anatomy of the aorta.
Pre-shaped structuring prevents mal-sealing adhesion on lesser curvature (Bird Beak).

2. Fenestrations
Najuta has single or multiple fenestrations created along its greater curvature to secure blood supply via the arch vessels. It enables to obtain enough sealing / landing zone and enlarge applicable zone on lesser curvature where aneurysms often occur.
