Six million people in the developed world are currently living with an aortic aneurysm and every year 750,000 new cases are diagnosed. Left untreated, aortic aneurysms tend to get larger and eventually rupture and when they do immediate death follows in up to 75% of cases.
Patients typically have no symptoms and, when they are diagnosed, they often undergo complex open surgical repair. Treating aortic aneurysms endovasculary, first reported in 1991 by Parodi and colleagues, offers a less invasive alternative.
The current endovascular approach to treating aortic aneurysm relies on the use of covered stents that mechanically blocks the aneurysm in an effort to eliminate it from circulation.
Despite going through several generational improvements covered stents, or stent grafts, are still bulky, difficult to deploy and are prone to leaks which tend to increase pressure within the aneurismal sac. Over 35% of aneurysms treated with covered stents continue to enlarge.
By creating an active barrier based on the laws of fluid dynamics Cardiatis Multilayer technology platform challenges the covered stent mechanical barrier concept and introduces a new paradigm for treating aortic aneurysms.
The space-age 3D geometrical design of a Cardiatis stent modifies flow within the aorta in a way that reduces pressure within the aneurysm thus collapsing the aneurismal sac while preserving any vital collateral circulation.
Cardiatis uncovered multilayer braided stent is low profile, easy to deploy and its hemodynamic modulating effects have been proven in-silico, in-vitro as well as clinically.
