Abstract
A method for releasing an aortic prosthesis includes positioning an introducer in femoral arteries of a patient. Guiding balloon catheters are positioned through the introducers to locate balloons thereof in terminal parts of common iliac arteries. The proximal aorta is clamped, balloons of the guiding catheters are inflated, and the aorta is opened for outside access. Distal ends of releasing balloon catheters are threaded through the guiding catheters and are recovered outside the patient through the introducers. Distal ends of the releasing catheters are connected to distal portions of the prosthesis, which is moved by the catheters until distal portions thereof contact the guiding catheters. The proximal part of the prosthesis is sutured to the aorta. The balloons of the releasing catheters are inflated to fix the distal portions of the prosthesis. Balloons are deflated, catheters are removed, the aorta is sutured, and the introducers are removed.
