The use of a novel short dilator tip on the distal bifurcated component during fenestrated aortic repair to avoid reno-visceral bridging stents.

The use of a custom short dilator introducer tip on the bifurcated device during FEVAR reduces the need to cross the fenestration bridging stent-grafts and may result in less fenestration related adverse events. However, the reno-visceral segment is still frequently crossed by the iliac extension which may lead to adverse events. This could likely be avoided by a similar adaptation on the iliac extension delivery system.
