ABSTRACT:
In a method in aortic surgery where the aorta of a patient is cut longitudinally to insert a prosthetic vessel or graft to bypass or remove an aneurysm, a plurality of closure elements or plugs are inserted into respective arterial tributaries, and particularly into their openings in the aortic wall, to stop blood backflow from the tributaries, thereby stemming blood loss during the surgery. The closure elements are provided with catch elements such as screw threads or shoulders for prventing inadvertant removal of the plugs from the tributaries. A recess or other element is provided at one end of the closure elements for receiving the operative head of a screwdriver or other tool to facilitate insertion of the closure elements into the branching blood vessels.
