Publication number: 20100224668Abstract: A system is provided for joining two tubular structures by a surgical stapling procedure. The system includes a series of sizers, a specifically designed graft, a loading unit, a wand, a tourniquet, and a stapling instrument. The sizers are for determining the diameter of a target aorta and the availability of a sufficient transected aortic length to perform a stapling procedure.
