Treat complex aneurysms with
Contour Neurovascular System™
With 6 key clinical studies and counting, the Contour Neurovascular System is proven to be effective in the treatment of aneurysms.
"The findings demonstrate that the Contour Neurovascular System is a promising technology for the endovascular embolization of cerebral aneurysms.
With its high occlusion rates and safety profile, Contour could be considered a viable alternative to existing intrasaccular devices."
Contour Neurovascular System for endovascular embolization of cerebral aneurysms: a multicenter cohort study of 10 European neurovascular centers
___________
Method:
Retrospective review of utilizing prospectively collected cases from 10 European neurovascular centers, gathered between February 2017 and October 2022.
