| 1. A method for releasing an aortic prosthesis, which comprises:
positioning an introducer in femoral arteries of a patient;
providing guiding balloon catheters with depth graduations and balloons;
positioning the guiding catheters through the introducers to locate the balloons in terminal parts of common iliac arteries;
clamping the proximal aorta, inflating the balloons of the guiding catheters, and opening the aorta for access from outside
the vessel;
threading distal ends of releasing balloon catheters through the guiding catheters and recovering the distal ends of the release
catheters outside the patient;
connecting distal ends of releasing catheters to distal portions of a prosthesis;
moving the prosthesis until distal portions of the releasing catheters contact the guiding catheters;
suturing a proximal part of the prosthesis to the aorta;
inflating the balloons of the releasing catheters to fix the distal portions of the prosthesis;
deflating the balloons of the releasing catheters and removing the releasing catheters;
deflating the balloons of the guiding catheters and removing the guiding catheters;
suturing the aorta; and
removing the introducers.
