METHOD OF IMPLANTING AN AORTIC STENT

摘要

A method of implanting an aortic stent comprising steps of: putting a main tube on a metal guide wire; moving the main tube along the metal guide wire to the descending aorta, the main tube is constrained by a first cover, and first and second tube bifurcations are branched from the main section; removing the first cover; inserting a second and third metal guide wire through the first tube bifurcation into the ascending aorta and branchiocephalic artery respectively; a first and a second tube branch moving into the ascending aorta and the branchiocephalic artery respectively; inserting a fourth and fifth metal guide wire through the first tube bifurcation into the ascending aorta and branchiocephalic artery respectively; a third and a fourth tube branch moving into left common carotid artery and the left subclavian artery respectively; removing a second cover constraining said tube branches.

1. A method of implanting an aortic stent including a main tube and a plurality of tube branches comprising steps of:
putting a main tube on a metal guide wire, the metal guide wire is attached to one end of a needle which is disposed in the aorta; moving the main tube along the metal guide wire to the descending aorta, the main tube is constrained by a first cover, and the main tube is bifurcated and comprises a main section having an outer diameter about equal to an inner diameter of a blood vessel of a descending aorta, and first and second tube bifurcations are branched from the main section; the first tube bifurcation includes a first membrane for dividing inside of the first tube bifurcation into a first space and a second space; the second tube bifurcation includes a second membrane for dividing inside of the second tube bifurcation into a third space and a fourth space ; the first space has an outer diameter, and said outer diameter of said first space, which corresponds to an inner diameter of an ascending aorta, is larger than outer diameters of the second space, the third space and the fourth space; removing the first cover; inserting a second metal guide wire through the first space into the ascending aorta, and a first tube branch moving along the second metal guide into the ascending aorta; inserting a third metal guide wire through the second space into the branchiocephalic artery, and a second tube branch moving along the third metal guide into the branchiocephalic artery; inserting a fourth metal guide wire through the third space into the left common carotid artery, and a third tube branch moving along the fourth metal guide into the left common carotid artery; inserting a fifth metal guide wire through the fourth space into the left subclavian artery, and a fourth tube branch moving along the fourth metal guide into the left subclavian artery; removing a second cover constraining said tube branches, wherein blood is configured to travel from the descending aorta and then to the main tube, the first space, the second space, the third space, and the fourth space.
