Aorfix™ gives you technology that conforms to patient anatomy, optimising both procedure and post-operative performance.
The Anatomy of Technology Durable, Flexible & AdaptableAorfix™ gives you the opportunity for single-intervention success by adapting to anatomy during and after the implantation.

“Aorfix™ is likely to increase the number of patients considered suitable for EVAR who were previously excluded from this type of treatment and also reduce the risk of endoleaks.”Horrocks,M.RetrospectiveAorfix™DatARetrievalRegistry(RADAR)Presentation.CharingCrossSymposium2009
“The device’s flexible design allows safe and accurate aneurysm sac exclusion in patients with highly challenging anatomy.”Balasubramaniam,K.,Hardman,J.,Horrocks,M.,Bulbulia,R.2009.TheadvantagesofAorfix™forendovascularrepairofabdominalaorticaneurysm.JournalofCardiovascularSurgery,50,2,139-143.
