INTRALUMINAL BYPASS - A DEVICE FOR RUPTURED AORTIC-ANEURYSM

A novel device was constructed and used to bypass a ruptured aortic an eurysm internally in vitro. Three human aortas each containing an abdo minal aneurysm were used for the production of transparent silicons ru bber replicas. A pulsatile flow within the range of physiological para meters was employed. The aortic aneurysms were ruptured iatrogenically . After positioning the device in the aneurysm, complete control of fl uid leakage through the ruptures was achieved. Normal flow through aor tic abdominal branches and distal to the aneuryms was maintained.
