Claim:
1. A method for performing a medical procedure using direct percutaneous access of an aorta, the method comprising: forming an incision through skin above a suprasternal notch; inserting a main sheath through the incision and positioning the main sheath against a posterior portion of a sternum; forming a purse-string suture in a wall of the aorta using instruments passed through the main sheath; forming an opening in the wall of the aorta in a region encircled by the purse-string suture; passing a distal end of an introducer sheath through the main sheath and through the opening into the aorta; delivering a replacement aortic valve through the introducer sheath into the aorta; withdrawing the introducer sheath from the opening; and while withdrawing the introducer sheath, applying tension to free ends of the purse-string suture, thereby tightening the purse-string suture to close the opening.
