1. A graft delivery system comprising:
- a first elongated instrument that is insertable into a patient'"'"'s vascular system, wherein said first elongated instrument comprises an aortic catheter and an aortic guide device capable of navigating said aortic catheter to said patient'"'"'s aorta at a predetermined location and is capable of protruding outside of said aorta;
a second elongated instrument that is insertable into said patient'"'"'s vascular system, wherein said second elongated instrument comprises a coronary catheter and a coronary guide device capable of navigating said coronary catheter to a coronary artery at a pre-determined location and is capable of protruding outside of said coronary artery;
a retrieving device capable of retrieving said aortic guide device and said coronary guide device and extracting said aortic guide device and said coronary guide device through a thoracic aperture in said patient; and
a third elongated instrument that is insertable from said exterior of said patient'"'"'s thoracic region into said patient through said thoracic aperture and is capable of being navigated by said coronary or said aortic guide device.

99. A method for installing a graft in a patient comprising;
-
a) protruding an aortic guide device from the aorta of said patient, thereby creating an aorta aperture;
b) protruding a coronary guide device to the outside of a coronary artery, thereby creating a coronary aperture;
c) navigating a third elongated instrument with said graft to said coronary aperture and attaching said graft to said coronary aperture; and
d) inserting the distal end of an aortic catheter into the proximal end of said graft and navigating the proximal end of said graft to said aorta aperture and attaching said graft to said aorta aperture.

100. A method for installing a mammary artery as a graft in a patient comprising:
-
a) navigating the distal end of a mammary guide device to protrude out of the severed end of a mammary artery;
b) protruding a coronary guide device to the outside of the coronary artery of said patient, thereby creating a coronary aperture;
c) navigating the distal end of a thoracic elongated instrument through the severed end of the mammary artery such that the distal end of the thoracic elongated instrument exits the patient; and
d) inserting the distal end of the coronary guide device into the proximal end of the thoracic elongated instrument and navigating the severed end of said mammary artery with the thoracic elongated instrument to the coronary aperture and attaching severed end to the coronary aperture.
