Blisters in arteries of the brain, called aneurysms, can pop causing a stroke and even death. Aneurysms in the middle of branching points, called bifurcation aneurysms, are difficult to treat and are typically treated with open brain surgery. Our solution is to place a spiral device inside the artery to spin the blood before it gets to the aneurysm. This pushes the blood against the side of the artery wall instead of letting it shoot straight down the middle at the aneurysm. We’re the only device that modifies the flow upstream to lower the risk of aneurysms popping.
