About

EndoStream Medical is an Israeli medical device company dedicated to developing safe and effective solutions that significantly improve clinical outcomes for patients suffering from brain aneurysms. The company's aneurysm devices utilize self-conforming scaffolds that adapt to an aneurysm's unique shape and provide maximal neck metal coverage. Their flagship product, Nautilus™, is an a-traumatic, self-conforming intrasaccular flow diverter that maximizes neck coverage and enhances coil stability to optimize intrasaccular thrombosis and enable progressive occlusion. The technology eliminates the need for blood thinners and anticoagulants, offering a safer and more effective alternative.
