Intraluminal Bypass: A Device for Ruptured Aortic Aneurysm

Abstract

A novel device was constructed and used to bypass a ruptured aortic aneurysm internally in vitro. Three human aortas each containing an abdominal aneurysm were used for the production of transparent silicons rubber replicas. A pulsatile flow within the range of physiological parameters was employed. The aortic aneurysms were ruptured iatrogenically. After positioning the device in the aneurysm, complete control of fluid leakage through the ruptures was achieved. Normal flow through aortic abdominal branches and distal to the aneuryms was maintained.
