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

75. A method for installing a graft in a patient comprising;
-
a) inserting an aortic guide device into an aorta from a thoracic region of said patient;
b) extracting said aortic guide device from said aorta to outside of a peripheral artery;
c) creating a coronary aperture to outside of a coronary artery with a coronary guide device;
d) navigating a third elongated instrument with said graft to said coronary aperture and attaching said graft to said coronary aperture; and
e) inserting the distal end of an aortic catheter that protrudes through the aorta aperture into the proximal end of said graft and navigating said proximal end of said graft to an aortic aperture and attaching said graft to said aortic aperture.

76. A method for installing a mammary artery as a graft in a patient comprising:
-
a) navigating the distal end of a mammary guide device from a thoracic region of said patient to and into an end of a mammary artery;
b) extracting said mammary guide device to outside of a peripheral artery;
c) creating a coronary aperture to outside of a coronary artery with a coronary guide device;
d) navigating one end of a thoracic elongated instrument through said end of said mammary artery; and
e) inserting the distal end of said coronary guide device into an end of said thoracic elongated instrument and navigating said end of said mammary artery with said thoracic elongated instrument to said coronary aperture and attaching said end of said mammary artery to said coronary aperture. - View Dependent Claims (93)
